Use GSlice to allocate all types of segments:
- char
- toggle
- mark
- pixbuf
- child widget
Char segments are a bit more complicated because the length of the text
is determined at run time and stored in the 'byte_count' field. If the
text is long, GSlice will call the system malloc() anyway, so it's
better to always use GSlice for GtkTextLineSegment.
Toggle segments are also freed in gtktextbtree.c, hence the function
_gtk_toggle_segment_free() (for a later commit it would be nice to
rename those functions with the _gtk_text prefix).

This commit was created using a script that searched for all docstrings
containing a parameter and the string 'or %NULL'.
Gdk backends and demos excluded as they are not part of a public API
https://bugzilla.gnome.org/show_bug.cgi?id=610474
The Gtk-custom.c file in gir-repository contained a number of
introspection annotations. Merge those into the GTK source files.
Some documentation was moved from the tmpl/ files to accomodate
the addition of annotations.

unnecessary copies.
2005-03-20 Matthias Clasen <mclasen@redhat.com>
Make PLT-reduction work with gcc4, and don't include
everything in gdkalias.h:
* gtk/grk.symbols: Group symbols by header and source file.
* gtk/makegtkalias.pl: Protect definitions by the same
preprocessor symbols used to guard the headers. Move
the alias declarations to a separate file which is
produced when calling makegtkalias.pl -def

this file.
* gtk/*.c: Include gtkalias.h after the other headers,

Add hidden aliases for exported symbols which are
used internally in order to get rid of many PLT
entries. (#145519, Arjan van de Ven)

The file can be processed by cpp to filter out certain
subsets of symbols.
* gtk/abicheck.sh: New file. Script to check the actually
symbols exported from libgtk-x11.2.0.so against the symbols
found in gtk.symbols.
* gtk/makegtkalias.pl: New file. Perl script to generate the
header containing the alias definitions for internally used
exported symbols from a list of symbols.
* gtk/gtkinternals.h: New file. An uninstalled header listing
symbols which must be exported for some reason and do not appear
in any other header.

* docs/README.linux-fb: note that this file is obsolete
* docs/Changes-2.0.txt, docs/Changes-1.2.txt: Add notes to these
files that they should not be edited and look in the reference
manual instead. Probably these files should just be replaced by
the note, and their main contents deleted.
* gtk/gtktextview.c: docs
* gtk/gtktextmark.c: docs
* gtk/gtktextchild.c: docs
* gtk/gtktextbuffer.c: docs stuff
* gtk/gtkclipboard.c (gtk_clipboard_get): fool with docs to maybe
give people more leads in sorting out PRIMARY vs. CLIPBOARD
2001-10-22 Havoc Pennington <hp@redhat.com>
* gtk/gtktextlayout.h: add a #error unless you define
GTK_TEXT_USE_INTERNAL_UNSUPPORTED_API, so people don't use this accidentally
* gtk/gtktext*.c: #define GTK_TEXT_USE_INTERNAL_UNSUPPORTED_API as appropriate.
Thu Aug 23 16:26:47 2001 Tim Janik <timj@gtk.org>
* gtk/gtktreeviewcolumn.c (gtk_tree_view_column_finalize):
* gtk/gtktextmark.c (gtk_text_mark_finalize): chain parent class
handlers, pointed out by Joshua N Pritikin <vishnu@pobox.com>.
2001-01-12 Havoc Pennington <hp@redhat.com>
* gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): offset the
current invalid region, fixes redraw bug while scrolling the
text widget
* gtk/gtktextview.c, gtk/gtktextview.h:
Rearrange the scrolling/validation/etc. code in a major way,
so it seems to make sense to me. Probably isn't genuinely that
much better, but...
* gtk/gtktexttag.c (set_fg_color): fix name of property used for
notifies

dangling pointers to the appearance attributes from the
line display
* gdk/gdkdraw.c (gdk_drawable_get_image): allow negative
width/height to mean "full width/height of drawable"

when getting log attrs. Get a slice, so that pixmaps and stuff
are properly handled.
* gtk/gtktextbuffer.c (paste): Fix pasting to work properly if you
paste into the selection (replaces selection now, previously
crashed or added to selection). Reveals longstanding btree bug -
select multiple lines, middle-click on the selection, boom. This
isn't related to my changes though.
* gtk/gtkentry.c (gtk_entry_move_forward_word): Update to reflect
PangoLogAttrs changes
(gtk_entry_move_backward_word): ditto
* gtk/gtktextlayout.h, gtk/gtktextlayout.c: Make the iter motion
functions return bool whether the iter moved onto a
dereferenceable position.
* gtk/gtktextview.h, gtk/gtktextview.c: Add a bunch of public
functions for motion in terms of display lines.
* gtk/gtktextmark.c (gtk_text_mark_get_buffer): Add function to
get the buffer a mark is inside

ensure_char_offsets() in front of code placing the iter in an
invalid state.
* gtk/gtktextbuffer.c (gtk_text_buffer_paste_primary):
make override_location arg const
(paste): Replace the selection if we paste into the
current selection
* gtk/gtkselection.h: Remove "GtkSelectioData"
(struct _GtkSelectionData): move the definition here.

Export the GTK_TEXT_BUFFER_CONTENTS target for in-process copies
* gtk/gtktextiter.c (gtk_text_iter_get_tags): New function
* gtk/gtktextbuffer.c (gtk_text_buffer_insert_range): implement
(gtk_text_buffer_insert_range_interactive): implement
(gtk_text_buffer_get_tags): Remove, replaced by
gtk_text_iter_get_tags()
* gtk/gtktextiter.c (gtk_text_iter_forward_search): Add a search
limit parameter, to avoid infinite linear scan.
(gtk_text_iter_backward_search): Add search limit

* gtk/gtktextview.c: Write API docs for all functions.
* gtk/gtktextview.h: add GTK_TEXT_WINDOW_PRIVATE as return value
for gtk_text_view_get_window_type() called on one of the private
windows.
* gtk/gtktextview.c: Instead of accessing text_view->buffer
directly, call get_buffer() which demand-creates a default
buffer. So gtk_text_view_new() can be used to create a view with a
default buffer in it, if you just want an empty text box users can
put data in. Useful for GUI builders also.
Wed Oct 25 20:47:41 2000 Tim Janik <timj@gtk.org>
* gtk/gdk-pixbuf-loader.c (gdk_pixbuf_loader_class_init): urg, removed
implementation of gtk_marshal_VOID__INT_INT_INT_INT. if people do that,
couldn't they at least give it a non-standard name?
* gtk/gtktextlayout.c: arg! yet another implementation of
gtk_marshal_VOID__INT_INT_INT_INT(), is this a conspiracy?
* gtk/gtktextbuffer.c: gotcha! captured a vagabonding
gtk_marshal_VOID__INT_POINTER_INT() implementation, braught it back
home. now i know this _is_ a conspiracy.
* gtk/gtkwidget.c (gtk_widget_class_init): marshaller fixups for
::state-changed.
* gtk/gtkaccelgroup.c (gtk_accel_group_create_remove):
(gtk_accel_group_create_add): marshaller signature fixups.
* gtk/gtklistitem.c (gtk_list_item_class_init): signal creation fixups,
pass in GTK_TYPE_SCROLL_TYPE instead of GTK_TYPE_ENUM.
* gtk/gtkobject.[hc]: removed GTK_CONNECTED flag, it's not valid
anymore.
Tue Oct 24 23:59:21 2000 Tim Janik <timj@gtk.org>
* docs/reference/Makefile.am: disabled SUBDIRS for the moment, since
due to the signal system changes, it wouldn't build currently. to
be fixed soon.
* docs/Changes-2.0.txt: GtkSignal/GSignal updates.
* gtk/gtkwidget.c: ::direction_changed takes an enum as argument,
so it needs gtk_marshal_VOID__ENUM() instead of
gtk_marshal_NONE__UINT().
* gdk/gdk*.c: adapted type registration functions.
* gtk/gtkbindings.c:
* gtk/gtkaccelgroup.c: operate on GSignalQuery, GtkSignalQuery is
gone.
* gtk/gtkenums.h: define GtkSignalRunType in terms of GSignalType.
* gtk/gtkobject.c:
(gtk_object_destroy):
(gtk_object_shutdown): fixed recursion guards. basically we have to
catch the case where any of GObject.shutdown() or gtk_object_destroy()
is called during ::destroy, and avoid recursion there.
* gtk/gtktypeutils.c:
* gtk/maketypes.awk: awk-script hackup to provide gtk_type_init() with
boxed_copy/boxed_free. this needs a more general solution based on a
publically installed code-generator utility.
* gtk/gtktypeutils.[hc]: compat aliased GTK_TYPE_BOXED to G_TYPE_BOXED,
glib's gobject has support for that now.
define GtkSignalMarshaller in terms of GSignalCMarshaller.
Mon Oct 23 09:36:42 2000 Tim Janik <timj@gtk.org>
* gtk/gtksignal.[hc]:
* gtk/gtkmarshal.[hc]:
* gtk/Makefile.am: generate marshallers with glib-genmarshal and don't
compile gtkmarshal.c on its own anymore, just include it in gtksignal.c.
removed #include <gtkmarshal.h>s all over the place, gtksignal.h takes
care of that.
* *.c: marshaller name fixups.
* gtk/gtkmarshal.list: added a comment briefing the format.
Sun Oct 22 23:14:39 2000 Tim Janik <timj@gtk.org>
* gtk/gtksignal.[hc]: nuked old implementation. we mostly have
compatibility macros here now. more specifically, most of
the API is preserved (yes, _most_, nonwithstanding the
following exceptions listed, the API is stil lHUGE ;)
things that got removed completely:
GtkSignalQuery, gtk_signal_query(), gtk_signal_n_emissions(),
gtk_signal_n_emissions_by_name(), gtk_signal_handlers_destroy(),
gtk_signal_set_funcs(), gtk_signal_handler_pending_by_id(),
gtk_signal_add_emission_hook(), gtk_signal_add_emission_hook_full(),
gtk_signal_remove_emission_hook().
non-functional functions variants:
gtk_signal_add_emission_hook(), gtk_signal_remove_emission_hook().
the GtkCallbackMarshal argument to gtk_signal_connect_full() is
not supported anymore.
(gtk_signal_compat_matched): new internal function to aid
implementation of the compatibility macros, it provides
functionality to block/unblock/disconnect handlers based
on func/data.
* gtk/gtkenums.h: define GtkSignalRunType in terms of GSignalType,
* *.c: adaptions to new type registration API signatures.
Fri Oct 20 15:26:33 2000 Tim Janik <timj@gtk.org>
* gtk/gtktypeutils.[hc]: removed G_TYPE_GTK_POINTER cludge.
2000-10-24 Havoc Pennington <hp@redhat.com>
* gtk/gtktextview.c (gtk_text_view_scroll_to_mark_adjusted): make
it a static function
* gtk/gtktextbtree.c (gtk_text_btree_tag): Gee, maybe we should
redraw text when a tag is applied to it.
* gtk/gtktexttag.c (gtk_text_tag_affects_size)
(gtk_text_tag_affects_nonsize_appearance): private functions to
see if a tag requires various kinds of redraw/layout to be queued
up.
* gtk/gtktexttag.h (struct _GtkTextTag): Remove relief crackrock
* gtk/testtext.c (fill_example_buffer): Put the cursor
at the start of the buffer, so search works by default

* gtk/gtktextbuffer.c (gtk_text_buffer_get_iter_at_line_index): New
function, get iter at a line + a byte index
* gtk/gtktextiter.c (gtk_text_iter_set_line_index): New function,
to set byte position within a line
(gtk_text_iter_check): remove leftover G_BREAKPOINT thing
2000-10-02 Havoc Pennington <hp@pobox.com>
* gtk/gtktextview.c: text_window_* weren't static and should have
been.
Start work on child widgets; not yet complete,
syncing to
office computer.
* gtk/gtktextchild.h: change this to contain a public interface,
starting work on child interfaces.
* gtk/gtktextchildprivate.h: move private interfaces here
* gtk/Makefile.am: update to reflect gtktextchildprivate.h
* gtk/gtktextview.h, gtk/gtktextview.c, gtk/gtktextbuffer.h,
gtk/gtktextbuffer.c, gtk/gtktextiter.h, gtk/gtk/textiter.c,

front of
internal functions
* gtk/gtktextchild.c (_pixbuf_segment_new): put _ in front of
internal function
* gtk/gtktextlayout.c (gtk_text_layout_get_line_display):
Reformatting
2000-09-30 Havoc Pennington <hp@pobox.com>
* gtk/gtktextbtree.c (gtk_text_btree_get_selection_bounds): Handle
NULL start/end pointers
* gtk/gtktextbuffer.c: Write some docs
(gtk_text_buffer_get_selection_bounds): Allow start/end to be
NULL, so you can just check whether there's a selection.
* gtk/gtktextbtree.c (gtk_text_btree_remove_mark): No need to
cleanup_line or segments_changed ourselves, it gets done
in unlink_segment
* gtk/gtktextmark.h:
s/gtk_text_mark_deleted/gtk_text_mark_get_deleted/
* gtk/gtktextsegment.h: Clean up some indentation and naming mess
* gtk/gtktextmark.c: delete some more old Tk cruft
* gtk/gtktextbuffer.c (gtk_text_buffer_delete_mark): add ref to
mark before removing it, so we can emit MARK_DELETED with a valid
pointer.
(gtk_text_buffer_mark_set): hold ref across signal emission
* gtk/gtktextbtree.c (gtk_text_btree_remove_mark): improve
whining about attempts to delete special marks
* gtk/gtktextbuffer.c (_gtk_text_buffer_spew): Prepend with
underscore, since it's internal.
* gtk/gtktextbuffer.h: Remove find_string prototype, this is
now implemented in terms of iterators in gtktextiter.h
* gtk/gtktextbuffer.c (gtk_text_buffer_set_text):
New function, destructively sets contents of buffer. Also
a convenient way to clear the buffer by setting text to ""
* gtk/gtktextiter.c (gtk_text_iter_make_surreal): reformat
multiline string literal
* gtk/testtext.c (text_changed_callback): Redraw line numbers if
text changes.
* gtk/gtktextiter.c (forward_char): Return FALSE if new location
is not dereferenceable
(gtk_text_iter_forward_lines): fix return value
2000-09-29 Havoc Pennington <hp@redhat.com>
* gtk/gtktexttag.c (gtk_text_tag_set_priority): fix indentation
* gtk/gtktextview.c: Implement drag thresholding; change functions
that set border window size to have nicer name
(gtk_text_view_mark_set_handler): Fix this to have the
right signature.
* gtk/testtextbuffer.c (fill_buffer): Update with pixbuf changes
* gtk/testtext.c: Update with API changes, put line numbers on
both sides.
* gtk/gtktextiter.c (gtk_text_iter_get_pixbuf): Replace get_pixmap
with this
* gtk/gtktextchild.h, gtk/gtktextchild.c: replace all pixmap with
pixbuf; delete a big block of #if 0 Tk code
* gtk/gtktextbuffer.c (gtk_text_buffer_insert_pixbuf): Replace
insert_pixmap with insert_pixbuf
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
2000-06-02 Havoc Pennington <hp@pobox.com>
* gtk/testtextbuffer.c: Test program to make sure GtkTextBuffer
is in working order.
* gtk/testtext.c: Change to reflect anonymous mark API
* gtk/gtktextview.c: Convert from mark names to GtkTextMark*.
* gtk/gtktexttag.h (struct _GtkTextTag): remove the affects_size
field, which was unused.
* gtk/gtktextmarkprivate.h (GTK_IS_TEXT_MARK): add this macro,
saves some typing.
* gtk/gtktextbuffer.c: Switch from mark names to GtkTextMark*
* gtk/gtktextbtree.c (gtk_text_btree_new): set the not_deleteable
flag on the insertion point and selection bound
Throughout, use GtkTextMark instead of GtkTextLineSegment, and
make mark-manipulation functions take a GtkTextMark* instead of a
mark name.
* gtk/gtktextmarkprivate.h: Add a "not_deleteable" flag to
GtkTextMarkBody; will be used to detect attempts to delete
the permanent marks (insert and selection bound)
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.
