ac79c0e799 textbuffer: Improve some get_iter apis
Make these functions return FALSE if they did not
return the exact position that was requested.

Adapt tests.

8282698201 textview: Use paintables instead of textures, and fix the support
This changes gtk_text_buffer_insert_texture() to
gtk_text_buffer_insert_paintable() which is strictly more useful
(as textures are paintables). It also fixes the code to actually
support drawing the paintables (as well as tracking changes
to the paintables.

a52757874e textbuffer: Add a content provider api
We need a content provider for the selection,
to implement DND, and the text buffer already
has one. Just add an api to get it.

15b3c0f563 textview: add undo/redo support to GtkTextView
This builds upon the GtkTextHistory helper to provide undo and redo support
for the GtkTextView widget and GtkTextBuffer object.

You can undo/redo using familiar shortcuts such as Primary+Z,
Primary+Shift+Z, ad Primary+Y.

Developers that wish to disable undo, should set the
GtkTextBuffer:enable-undo property to FALSE.

You can wrap irreversible actions
gtk_text_buffer_begin_irreversible_action() and
gtk_text_buffer_end_irreversible_action(). This will cause the undo stack
to drop all undo/redo actions and the changes made between them will be
the "initial state" of the buffer.

Calling gtk_text_buffer_set_text() will do this automatically for you.

4c150d8eb5 The big versioning cleanup
Remove all the old 2.x and 3.x version annotations.
GTK+ 4 is a new start, and from the perspective of a
GTK+ 4 developer all these APIs have been around since
the beginning.

gtk_text_buffer_insert_pixbuf and GtkTextBuffer::insert-pixbuf,
which have all been replaced by texture equivalents.

Update all callers.

fde91c3bec Revert "textbuffer: nicer get_iter functions"
This reverts commit a9a1c00cc9.

Unfortunately, adding the boolean return broke both the python
and javascript bindings, since they now return a tuple consisting
of the boolean and the out argument.

a9a1c00cc9 textbuffer: nicer get_iter functions
Avoid crashes when passing an invalid location to a
gtk_text_buffer_get_iter_at_*() function.

A boolean is returned to know if @iter has been set to the exact
location.

Unit tests are added.

2008-05-28  Michael Natterer  <mitch@imendio.com>

	* gtk/gtk.h: define __GTK_H_INSIDE__ around including all other
	headers.

	* gtk/gtktypebuiltins.h.template
	* gtk/gtkversion.h.in
	* gtk/gtk*.h: add single-include guards that #error out if
	GTK_DISABLE_SINGLE_INCLUDES is defined and any of these files is
	included individually.

	* gtk/gtkprinter-private.h
	* gtk/gtktextlayout.h
	* gtk/gtktexttagprivate.h
	* gtk/gtktexttypes.h
	* gtk/gtktreedatalist.h: include <gtk/gtk.h> instead of individual
	headers in these private or semi-private headers.

	* gtk/gtkimmodule.h: also here because it's not in gtk.h.

	* gtk/gtkpagesetupunixdialog.h

	* gtk/gtkprintjob.h
	* gtk/gtkprintunixdialog.h: likewise in the gtkunixprint headers.

	instead of individual headers in these deprecated headers. They
	don't get included at all when GTK_DISABLE_DEPRECATED is defined,
	so if an app needs them anyway, it must undef GTK_DISABLE_DEPRECATED
	and include them individually, which should continue to work.

	* gtk/gtkclist.c: include "gtkctree.h" because of the change
	above.

6c1d990adc Add infrastructure for copy/paste and DND of rich text for GtkTextBuffer.
2006-03-07  Michael Natterer  <mitch@imendio.com>

	Add infrastructure for copy/paste and DND of rich text for
	GtkTextBuffer. Fixes bug #324177.

	* gtk/gtktextbufferrichtext.[ch]: new files implementing a
	per-buffer registry of rich text formats.

	* gtk/gtk.h: #include gtktextbufferrichtext.h

	* gtk/gtktextbufferserialize.[ch]: new files implementing an
	internal serialization format that can handle all of a text
	buffer's tags and pixbufs. It's not useful for anything except
	tranfer between instances of GtkTextBuffer (Anders Carlsson).

	* gtk/Makefile.am: build the new files.

	* gtk/gtkclipboard.[ch]: added convenience APIs for rich text,
	just as they exist for plain text and pixbufs.

	* gtk/gtkselection.[ch]: added rich text convenience APIs here
	too.  Return the target list from gtk_target_list_ref(). Register
	GtkTargetList as boxed type. Added
	gtk_target_table_new_from_list() and gtk_target_table_free(),
	which make converting between GtkTargetList and arrays of
	GtkTargetEntry considerably easier.

	* gtk/gtktextutil.[ch]: added _gtk_text_util_create_rich_drag_icon()
	which creates a fancy rich text icon (Matthias Clasen).

	* gtk/gtktextbuffer.[ch]: use all the new stuff above and
	implement copy and paste of rich text. Added APIs for getting the
	target lists used for copy and paste. Added public enum
	GtkTextBufferTargetInfo which contains the "info" IDs associated
	with the entries of the target lists.

	* gtk/gtktextview.c: use the new rich text APIs and
	GtkTextBuffer's new target list API to enable DND of rich text
	chunks.

	* gtk/gtk.symbols: export all the new symbols added.

	* tests/testtext.c: added rich text testing stuff.

	* pixops/pixops.c (pixops_process): merge fix from stable: Patch
	 from hoshem@mel.comcen.com.au to fix nonzero X offsets.  Fixes
	 bug #50371.

        * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest): merge
	from stable: Patch from OKADA Mitsuru <m-okada@fjb.co.jp> to fix
	confusion of using "src" instead of "p".
        (pixops_composite_color_nearest): Use a more accurate (and
	correct, to begin with) compositing method.  This cures checks
	showing through on images with no alpha.

	* gdk-pixbuf.c (gdk_pixbuf_fill): fix bug that left some trailing
	bytes unfilled.

	* gdk-pixbuf-io.h: fix UpdatedNotifyFunc to use signed ints

	* gdk-pixbuf-loader.h (struct _GdkPixbufLoaderClass): Change
	area_updated signal to use signed ints.  Removed animation-related
	signals.

	* io-gif.c, io-gif-animation.h, io-gif-animation.c: Massive
	rewrite action

	* gdk-pixbuf-animation.c: Add GdkPixbufAnimationIter to abstract
	all the pesky details. Remove old frame-based API. Make
	GdkPixbufAnimation an abstract base class, derived by the loaders.
