/**
* SECTION:gtkeditable
* @Short_description: Interface for text-editing widgets
* @Title: GtkEditable
*
* The #GtkEditable interface is an interface which should be implemented by
2011-11-28 15:23:00 +00:00
* text editing widgets, such as #GtkEntry and #GtkSpinButton. It contains functions
* for generically manipulating an editable widget, a large number of action
* signals used for key bindings, and several signals that an application can
* connect to to modify the behavior of a widget.
*
* As an example of the latter usage, by connecting
2011-11-28 15:23:00 +00:00
* the following handler to #GtkEditable::insert-text, an application
* can convert all entry into a widget into uppercase.
*
* ## Forcing entry to uppercase.
*
* |[<!-- language="C" -->
* #include <ctype.h>;
*
* void
* insert_text_handler (GtkEditable *editable,
* const char *text,
* int length,
* int *position,
* gpointer data)
* {
* char *result = g_utf8_strup (text, length);
*
* g_signal_handlers_block_by_func (editable,
* (gpointer) insert_text_handler, data);
* gtk_editable_insert_text (editable, result, length, position);
* g_signal_handlers_unblock_by_func (editable,
* (gpointer) insert_text_handler, data);
*
* g_signal_stop_emission_by_name (editable, "insert_text");
*
* g_free (result);
* }
* ]|
*
* ## Implementing GtkEditable
*
* The most likely scenario for implementing GtkEditable on your own widget
* is that you will embed a #GtkText inside a complex widget, and want to
* delegate the editable functionality to that text widget. GtkEditable
* provides some utility functions to make this easy.
*
* In your class_init function, call gtk_editable_install_properties(),
* passing the first available property ID:
*
* |[
* static void
* my_class_init (MyClass *class)
* {
* ...
* g_object_class_install_properties (object_class, NUM_PROPERTIES, props);
* gtk_editable_install_properties (object_clas, NUM_PROPERTIES);
* ...
* }
* ]|
*
* In your interface_init function for the GtkEditable interface, provide
* an implementation for the get_delegate vfunc that returns your text widget:
*
* |[
* GtkEditable *
* get_editable_delegate (GtkEditable *editable)
* {
* return GTK_EDITABLE (MY_WIDGET (editable)->text_widget);
* }
*
* static void
* my_editable_init (GtkEditableInterface *iface)
* {
* iface->get_delegate = get_editable_delegate;
* }
* ]|
*
* You don't need to provide any other vfuncs. The default implementations
* work by forwarding to the delegate that the #GtkEditableInterface.get_delegate()
* vfunc returns.
*
* In your instance_init function, create your text widget, and then call
* gtk_editable_init_delegate():
*
* |[
* static void
* my_widget_init (MyWidget *self)
* {
* ...
* self->text_widget = gtk_text_new ();
* gtk_editable_init_delegate (GTK_EDITABLE (self));
* ...
* }
* ]|
*
* In your dispose function, call gtk_editable_finish_delegate() before
* destroying your text widget:
*
* |[
* static void
* my_widget_dispose (GObject *object)
* {
* ...
* gtk_editable_finish_delegate (GTK_EDITABLE (self));
* g_clear_pointer (&self->text_widget, gtk_widget_unparent);
* ...
* }
* ]|
*
* Finally, use gtk_editable_delegate_set_property() in your set_property
* function (and similar for get_property), to set the editable properties:
*
* |[
* ...
* if (gtk_editable_delegate_set_property (object, prop_id, value, pspec))
* return;
*
* switch (prop_id)
* ...
* ]|

(Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_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_cursor, kill_word, etc, etc, etc). removed the time argument from gtk_editable_cut/copy/paste_clipboard (source but not binary incompatible...) Instead get time from gtk_get_current_event (). * gtk/gtktext.c gtk/gtkentry.c: Support the new editable signals. Thu Jun 18 02:52:09 1998 Owen Taylor <otaylor@gtk.org> Patches from Damon Chaplin <DAChaplin@email.msn.com>: gtk/gtkfontsel.h: Fixed GtkFontSelectionClass - I forgot to change parent class to GtkNotebookClass when splitting the widget in two. Also updated some comments. gtk/gtkfontsel.c: Fixed bug when toggling 'Allow scaled bitmaps' button without a font selected. Fixed bug in set_font_name - I hadn't updated the code to search for the style in the font_style clist - it was still assuming the style row was equal to its index, but it isn't any more. Changed 'Reset' button on filter page to 'Clear Filter'. Deleted old code relating to the old 'Filter Fonts' toggle Updated some comments. Cleared 'Actual Fontname' if no font is set. gtk/testgtk.c: Fixed problem when 'OK' button is pressed - it was destroying the GtkFontSelection instead of the GtkFontSelectionDialog. Thu Jun 18 02:15:31 1998 Owen Taylor <otaylor@gtk.org> * gtk/gtkmain.c (gtk_init): Added --g-fatal-warnings flag to make all warnings fatal errors. * gtk/testthreads.c: moved <pthreads.h> include inside #ifdef USE_PTHREADS Thu Jun 18 01:37:31 1998 Owen Taylor <otaylor@gtk.org> * gtk/gtkenums.h gtk/gtkcontainer.[ch] gtk/gtkwidget.c gtk/gtkmenu.c gtk/gtkviewport.c gtk/gtkwindow.c: - Added new function gtk_container_set_resize_mode() for fine-grained control of where resize-queueing is done. - Removed GtkContainer::need_resize and GtkWindow::move_resize - Added GtkContainer::check_resize to replace need_resize. - Added function gtk_container_check_resize() to trigger queued resizes, and gtk_container_resize_children() to Figure which children need to be size-allocated. (logic moved from gtkwindow.c) - Reorganized code in gtkwindow.c - Set the resize-mode for viewports so that resizes within a viewport don't propagate out of it.
