Wed Jun 21 11:41:43 2000  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtkentry.c gtk/gtkimcontextsimple.c gtk/gtklabel.c
	gtk/gtktexttypes.c gtk/testtext.c modules/linux-fb/basic.c:
	Remove use of libunicode in favor of new GLib functions.

	* gtk/gtkcolorsel.c: Remove conditional includes for FB, win32,
	nano-x, framebuffer. The X11 include is just a hack until we get
	the necessary functions in gdkcolor.h, so there is no reason to
	add other includes of platforms.

	* gtk/gtkwindow.c (gtk_window_compute_default_size): Revert 
	window bigger than the screen change.

        * gtk/testgtk.c: Revert some random changes from Elliot
	that had no particular point and were causing testgtkrc
	not to function correctly.
	
	* gdk/gdkregion-generic.h: Revert change from Elliot. Just
	because GdkSegment and GdkRegionBox have the same fields,
	it doesn't mean that 'typedef GdkSegment GdkRegionBox'
	results in clearer code.

	* gdk/x11/gdkinput-x11.c (gdk_input_common_select_events,
	gdk_input_translate_coordinates): Fix missed GdkObjectification

	* gdk/Makefile.am, gdk/*/Makefile.am: Fix conditionality to work the "right" way.
	* gtk/gtk{plug,socket}.h: Missed commits from previous.

2000-06-20  Havoc Pennington  <hp@redhat.com>

	* modules/linux-fb/Makefile.am: Make this compile
	without framebuffer enabled

	* gdk/linux-fb/Makefile.am: Add conditional to not build
	framebuffer unless specified in configure

	* gdk/gdkdraw.c (gdk_draw_drawable): Fix bug where I was getting
	the size of the target instead of source if -1 was passed for
	width/height

	* gdk/x11/gdkgeometry-x11.c (gdk_window_compute_position): Fix 
	width/height confusion.

2000-06-19  Havoc Pennington  <hp@redhat.com>

	* gdk/x11/gdkx.h (GDK_WINDOW_XWINDOW): change this to be
	GDK_DRAWABLE_XID. In the future, we probably want to make it
	faster with G_DISABLE_CHECKS turned on.

2000-06-14  Havoc Pennington  <hp@redhat.com>

        * gdk/Makefile.am: add gdkpixmap.c

	* gdk/gdk.c: s/gdk_window_init/_gdk_windowing_window_init/
	s/gdk_image_init/_gdk_windowing_image_init

	* gdk/gdkcolor.c: make ref/unref compat wrappers for GObject
	ref/unref

	* gdk/gdkcolor.h: make GdkColormap a GObject subclass

	* gdk/gdkcompat.h: remove GdkWindowType compat, since
	GdkWindowType is now non-deprecated; 
	change gdk_window_get_type() compat to be
	gdk_window_get_window_type().

	* gdk/gdkdnd.h: make GdkDragContext a GObject.

	* gdk/gdkdraw.c, gdk/gdkdraw.h: Convert GdkDrawable to a pure
	virtual GObject. Make all functions call into the vtable.
	Move gdk_image_put() guts in here. Remove GdkDrawableType
	and gdk_drawable_get_type(), these are now GdkWindow-specific.
	draw_image, get_depth, get_size, set_colormap, get_colormap,
	get_visual added to the vtable.
	
	* gdk/gdkgc.h, gdk/gdkgc.c: Convert GdkGC to a pure virtual 
	GObject. Virtualize everything. 
	(gdk_gc_new_with_values): remove check for destroyed window,
	because now GdkWindow::create_gc will check this.
	(gdk_gc_set_values): New function to set GC values, this 
	was already implemented but wasn't in the header

	* gdk/gdkimage.h, gdk/gdkimage.c: Convert GdkImage to a GObject.

	* gdk/gdkinternals.h: Remove _gdk_window_alloc(), remove
	_gdk_window_draw_image(), remove _gdk_windowing_window_class,
	remove _gdk_window_class; add _gdk_window_impl_get_type() and
	_gdk_pixmap_impl_get_type(). Rename gdk_window_init to
	_gdk_windowing_window_init, rename gdk_image_init to
	_gdk_windowing_image_init.
	
	* gdk/gdkpango.c: Reflect GObject-ification of PangoContext.
	(gdk_draw_layout): Remove check for destroyed window, 
	because all the drawable methods already check it.
	
	* gdk/gdkpixmap.h, gdk/gdkpixmap.c: Convert GdkPixmap to GObject.
	Add gdkpixmap.c which contains implementation of GdkDrawable
	virtual table (by chaining to a platform-specific implementation
	object).
	
	* gdk/gdkprivate.h: Remove GDK_IS_WINDOW, GDK_IS_PIXMAP, 
	GDK_DRAWABLE_DESTROYED. Add GDK_WINDOW_DESTROYED. Replace
	GDK_DRAWABLE_TYPE with GDK_WINDOW_TYPE. Remove GdkDrawablePrivate,
	GdkWindowPrivate, GdkImageClass, GdkImagePrivate, GdkGCPrivate,
	GdkColormapPrivate. 

	* gdk/gdktypes.h: #include <glib-object.h>

	* gdk/gdkwindow.h, gdk/gdkwindow.c: Convert GdkWindow to GObject.
	Move most functionality to platform-specific implementation
	object. GdkWindow itself now handles the backing store, then
	chains to the platform-specific implementation.
	(gdk_window_get_window_type): return GdkWindowType of the window.
	(gdk_window_peek_children): New routine, returns the children of 
	a GdkWindow
	(gdk_window_get_children): Was in X11-specific code and did 
	XQueryTree. Changed to simply return a copy of window->children; 
	so it can go in cross-platform code.
	
	* gdk/x11/Makefile.am: fix broken MKINSTALLDIRS path

	* gdk/x11/gdkcolor-x11.c: implement X-specific parts of 
	GdkColormap; just changed to use the new private data instead
	of casting to GdkColormapPrivate.

	* gdk/x11/gdkcursor-x11.c: added a couple typechecks to 
	gdk_cursor_new().

	* gdk/x11/gdkdnd-x11.c: Change the way we access private fields 
	(private data member in the GObject). 
	(xdnd_manager_source_filter): Function had broken 
	error handling, fix it (use gdk_error_trap_push).

	* gdk/x11/gdkdrawable-x11.c: This file now implements
	a base class for GdkWindowImplX11/GdkPixmapImplX11. This 
	base class is purely for the convenience of the X port,
	and not part of the interface to cross-platform GDK.

	* gdk/x11/gdkevents-x11.c: Reflect various renamings.
	
	* gdk/x11/gdkgc-x11.c: Implement a subclass of GdkGC that's
	specific to X, and returned by the create_gc virtual method
	of GdkDrawableImplX11. 
	(gdk_x11_gc_set_dashes): Change this to take an array of gint8
	rather than gchar, this was also changed in the GdkGC vtable.
	(gdk_x11_gc_values_to_xvalues): If GdkGCValues is NULL, or the
	mask is 0, return immediately, instead of checking every flag.
	This is faster, and keeps us from segfaulting if values is NULL
	and the mask contains some nonzero flags.

	* gdk/x11/gdkgeometry-x11.c: deal with all the rearranging of
	GdkWindow.

	* gdk/x11/gdkglobals-x11.c: change type of grab window, since 
	GdkWindowPrivate is gone.

	* gdk/x11/gdkim-x11.c: rename things that got renamed.

	* gdk/x11/gdkimage-x11.c: implement in terms of GObject, and 
	remove the image_put stuff that got transferred to GdkDrawable.
	
	* gdk/x11/gdkinput.c: renamings

	* gdk/x11/gdkmain-x11.c: #include <pango/pangox.h>

	* gdk/x11/gdkpixmap-x11.c: GObject conversion

	* gdk/x11/gdkprivate-x11.h: indentation fixes

	* gdk/x11/gdkproperty-x11.c: renamings

	* gdk/x11/gdkselection-x11.c: renamings

	* gdk/x11/gdkwindow-x11.c: Restructuring and renaming; this now 
	implements the platform-specific "impl" object.
	Moved gdk_window_get_children to gdk/gdkwindow.c

	* gdk/x11/gdkx.h: Remove all the private structs and private datas
	that no longer exist. Add declaration of GdkGCX11 object here.
	Fix all the macros to still work. 

	* gtk/gtk-boxed.defs: Remove GtkStyle, GdkColormap, GdkWindow,
	GdkDragContext from the boxed types since they are now GObjects.

	* gtk/gtkstyle.h, gtk/gtkstyle.c: Converted GtkStyle to a GObject,
	moved xthickness/ythickness into the instance. GtkStyleClass
	functions are now in the standard vtable for GtkStyle, so you have
	to create a GObject subclass to write a theme engine.
	(gtk_style_copy): fixed a leaked PangoFontDescription
	(gtk_style_init): renamed gtk_style_realize, so gtk_style_init
	can be the standard GObject function.
	
	* Throughout GTK:
	s/style->klass->[xy]thickness/style->[xy]thickness
	s/pango_layout_unref/g_object_unref/

	* gtk/gtkrc.h, gtk/gtkrc.c: Converted GtkRcStyle to a GObject.
	
	* gtk/gtksocket.c: Use gdk_window_get_user_data() instead of 
	accessing GDK internals.

	* gtk/gtkwidget.c: Use gdk_window_peek_children() instead of 
	accessing GDK internals.

2000-06-18  Elliot Lee  <sopwith@redhat.com>

	* gtk/gtkwindow.c: Don't allow creation of a window bigger than the screen.

	* gtk/gtkrange.c: Fix the mega-jumpy-with-lagged-events scrollbar
 	problem by calculating event position relative to the trough
 	rather than the slider.
	* gtk/gtkdnd.c, gtk/gtkcolorsel.c: Include FB headers if appropriate.

	* gdk/gdkgc.h: Add GDK_NOR.

	* configure.in, Makefile.am: Add modules top level dir
	* configure.in: Only use pangox library if building x11 target.
	* gdk/gdkdnd.h: Add GDK_DRAG_PROTO_LOCAL enum for future intra-app use.

	private_data throughout the file.

	* gtk/gtkcolorsel.h (struct _GtkColorSelection): Change private to
	private_data to avoid clashing with keyword.

Fri Jun 16 22:24:22 2000  Christopher Blizzard  <blizzard@redhat.com>

	Byelorussian language; changed the Makefile and file names 
	to reflect that.

Mon Jun 12 16:58:40 2000  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtkwindow.c (gtk_window_unmap): Call gdk_window_withdraw
	rather than gdk_window_hide; this makes things work
	correctly if the window is programmatically hidden while
	iconified.

Sun Jun 11 10:22:36 2000  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtkselection.c (gtk_selection_bytes_per_item):
	Add helper function to compute format / bytes 
	relationship. Use in a couple places to fix up
	errors which assume 8 * format.

	* gtk/gtkselection.c (gtk_selection_request): Use 32
	rather than 8 * sizeof (GdkAtom), to work correctly
	on Alpha.

	libgtk.la
	(LDADDS): include libgtk-x11.la and libgdk-x11.la, not the non-x11
	versions

	* gtk/gtklabel.c (gtk_label_get_text): Make sure that the error
	checking macros return NULL since the function has a return value.

Wed Jun  7 15:44:42 2000  Owen Taylor  <otaylor@redhat.com>

	* configure.in, gtk-config.in, gdk/Makefile.am, gdk/*/Makefile.am,
	gtk/Makefile.am: make it possible to configure gtk for different
	targets on the same platform. The library name is now 
	libgtk-$target-$version.so. gtk-config accepts a --target x11|nanox|linux-fb
	flag. Only the x11 target compiles right now.
	* gdk/gdkregion-generic.h, gdk/gdkregion-generic.c, gdk/gdkpoly-generic.h,
	gdk/gdkpolyreg-generic.c: move generic region code in the main GDK dir.
	* gdk/nanox/gdk*generic*: delete generic region code.
	* gdk/linux-fb/gdk*generic*: delete generic region code.
	* README.nanox: update information.

	* gdk/gdk.c (gdk_init_check): Add call to g_type_init() - we'll
	need this later, and this makes sure that the atexit for
	glib gets called after that for GDK, so atexits are
	properly ordered for object leak checking.

	* gdk/gdk.c (gdk_exit_func): Call gdk_windowing_exit().

	* gdk/x11/gdkmain-x11.c (gdk_windowing_exit): Call 
	pango_x_shutdown_display()

	* gdk/x11/gdkevents-x11.c: Hack gdk_event_get_graphics_expose()
	to sort of work by adding an extra return_exposes arg
	to gdk_event_translate() - it might be better to simply
	deprecate the function altogether and force people to rewrite
	without it. gdk_window_scroll() handles most of it, and where
	gdk_window_scroll() doesn't work, simply redrawing more does.

	* gtk/gtkwidget.c (gtk_widget_set_default_direction): Fix up
	assertion.

	* gtk-config.in: Include PANGO_CFLAGS/LIBS.

	* gdk/x11/gdkevents-x11.c (gdk_event_translate): Remove a 
	bunch of pretty much useless /* Print debugging info */ comments 
	which had drifted away from the code they were commenting.

        * 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)

	* gtk/Makefile.am (noinst_PROGRAMS): add testtextbuffer

	* gtk/gtkwidget.c (gtk_widget_draw) gtk/gtkmain.c (gtk_main_do_event): 
	Honor DOUBLE_BUFFRED_FLAG

	* gtk/gtkwidget.c (gtk_widget_set_double_buffered): Add a
	function to set the DOUBLE_BUFFERED flag.

	* gtk/gtkwidget.h: Add GTK_DOUBLE_BUFFERED flag to indicate whether
	or not exposes done on the widget should be double-buffered.

	* gtk/gtkenums.h (GtkTextDirection): Reverse order of enumerations
	to be what would be expected. (Fixes problem with a

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
