Fri Nov 19 10:34:41 1999  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtkgamma.h: Adapt cast macros to standard.

[ Merges from 1.2 ]

Tue Nov 16 10:15:54 1999  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtkitemfactory.c (gtk_item_factory_parse_path):
	If translation does not include a '/', use entire
	translation instead of crashing.

Sun Oct 31 22:21:11 1999  Tim Janik  <timj@gtk.org>

	* docs/gtk_tut.sgml:
	s/gtk_accel_group_attach/gtk_window_add_accel_group/.

Sat Oct 30 09:09:09 1999  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtkselection.c (gtk_target_list_remove): Use
	g_list_remove_link, not g_list_remove.

	[ From Geert Bevin <gbevin@thunderstorms.org> ]

Sun Oct 24 07:41:40 1999  Tim Janik  <timj@gtk.org>

	* gtk/gtkclist.c (real_undo_selection): commented out g_print()
	statement upon unselection (how the heck did that slip in?).

Sat Oct 23 03:03:08 1999  Tim Janik  <timj@gtk.org>

	* gtk/gtktext.c (gtk_text_freeze):
	(gtk_text_thaw): undraw/draw cursor here to avoid unnecessary scrolling
	in frozen state (and aparently crashes). patch provided by Anders
	Melchiorsen <and@kampsax.dtu.dk>.

Sat Oct 23 02:53:20 1999  Tim Janik  <timj@gtk.org>

	* fix insensitive default/focus widget activation,
	reported by Matt Goodall <mgg@isotek.co.uk>.

	* gtk/gtkwindow.c (gtk_window_key_press_event):
	(gtk_window_activate_default):
	(gtk_window_activate_focus):
	return handled=FALSE for actiavtion of insensitive default
	widgets. return handled=TRUE for activation of insensitive
	focus widgets. don't activate in either case.

Tue Oct 19 09:55:08 1999  Owen Taylor  <otaylor@redhat.com>

	* gtk-config.in (lib_gtk): Switch order of @x_cflags@
	and $glib_cflags to match library order and in the
	theory that an old version of GLib is more likely to
	be in the include directory for X then vice-versa.
	(Bug #2776)

Tue Oct 19 09:46:49 1999  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtkrc.c (gtk_rc_init): Always use LC_CTYPE
	to determine the locale for fontsets, not LC_MESSAGES;
	the user may want English messages with a handling
	for non-English languages. (LC_CTYPE=ru_RU LC_MESSAGES=fr_FR
	will still be broken) (Bug #2891)

Tue Oct 19 20:36:42 1999  Changwoo Ryu  <cwryu@adam.kaist.ac.kr>

	* gtk/gtkrc.ko: Fixed the wrong number of "*"'s.

Tue Oct 19 12:15:13 1999  Changwoo Ryu  <cwryu@adam.kaist.ac.kr>

	* gtk/gtkrc.ko: Changed the Korean default fontset.

Fri Oct  8 02:32:47 1999  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtklayout.c (gtk_layout_adjustment_changed): Fix bug
	where when scrolling to the left or top double exposes
	were done, causing major slowdowns.

Thu Oct  7 18:31:55 1999  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtkrc.c (gtk_rc_init): Always normalize codeset
	names to lowercase and alphanumeric, before looking
	them up.

	* gtk/Makefile.am: Install codeset variant gtkrc files
	with normalized names.

Thu Oct  7 22:52:42 1999  Tim Janik  <timj@gtk.org>

	* gtk/gtkitemfactory.c (gtk_item_factory_popup_with_data): even
	popup menus when the menu is already visible, but its parent
	is still hidden, (happens after tornoff window got hidden).

Thu Oct  7 11:09:55 1999  Owen Taylor  <otaylor@redhat.com>

	* gtk/Makefile.am (install-data-local): Fix
	a typo where gtkrc.vi_VN.tcvn5712 wasn't getting
	deleted, causing error messages on install.

Thu Oct  7 11:03:06 1999  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtk[hv]paned.c (gtk_{h,v}paned_draw): Redraw
	the handle as well, since we now sometimes ignore
	exposes on the handle while resizing.

Wed Oct  6 18:02:31 1999  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtkrc.c (gtk_rc_append_default_pixmap_path): Fix stupid
	extra g_free introduced in one of the last one or two
	commits.

Wed Oct  6 16:38:36 1999  Owen Taylor  <otaylor@redhat.com>

	* gtk/Makefile.am gtk/gtkrc*: Make naming of gtkrc files
	consistent, put each style that a gtkrc.* file creates
	in a unique namespace, remove old files before installing.

Wed Oct  6 14:31:16 1999  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtkrc.c (gtk_rc_init): Avoid leaking memory when
	gtk_rc_init is called multiple times. (Yes, people who
	do that have bugs in their code.)

Tue Oct  5 11:36:57 PDT 1999 Manish Singh <yosh@gimp.org>

	* gtk/Makefile.am: listing gtkrc in gtkconf_DATA seems to barf.
	Remove it since it's generated by the Makefile anyway

Tue Oct  5 02:43:41 1999  Owen Taylor  <otaylor@redhat.com>

	* gdk/gdkinputcommon.h (gdk_input_device_new): Free
	device->info.axes for core pointer.

Thu Sep 30 13:55:25 1999  Owen Taylor  <otaylor@redhat.com>

	* gtk/testgtk.c (destroy_idle_test): Rename idle to
	idle_id, to deal with obsolete, broken C libraries.

Mon Sep 27 02:50:15 1999  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtkvscale.c (gtk_vscale_draw): Don't add in
	allocation->x/y twice!

	* gtk/gtkhscale.c: Make usage of gtk_hscale_pos_trough()
	consistent with gtk_vscale_pos_trough().

Sun Sep 26 19:44:34 1999  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtkcontainer.c (gtk_container_queue_resize): We may
	be queueing a resize on a toplevel container between
	the time we show it and when we map it. So, we need
	to test GTK_WIDGET_VISIBLE() for toplevels, and only
	use GTK_WIDGET_DRAWABLE() for child windows.

Thu Sep 23 16:41:03 1999  Owen Taylor  <otaylor@redhat.com>

	* gtk/Makefile.am (LDADDS): Add GDK_WLIBS to LDADDS
	(fixes bug #2144)

Fri Sep 24 00:51:45 1999  Tim Janik  <timj@gtk.org>

	* gtk/gtkcontainer.c (gtk_container_queue_resize): check for
	container DRAWABLE (instead of VISIBLE), so we don't queue
	resizes on non-toplevel containers.

Sun Sep 19 18:13:31 1999  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtkselection.[ch]: Make the data argument
	const guchar *.

Sat Sep 18 21:27:40 1999  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtkwindow.c: Try to behave sensibly if
	the focus widget is the window itself. (Should
	we allow this at all?)

Fri Sep 17 09:57:15 1999  Tim Janik  <timj@gtk.org>

	* gtk/gtkwidget.c (gtk_widget_set_sensitive):
	* gtk/gtknotebook.c (gtk_notebook_set_scrollable):
	* gtk/gtknotebook.c (gtk_notebook_set_show_border):
	* gtk/gtkclist.c (gtk_notebook_set_show_border): make gboolean args
	in prototypes and implementations consistent (Tomas Ogren).

	* gtk/gtklayout.c (gtk_layout_remove): unset GTK_IS_OFFSCREEN flag
	before the widget is unparented (reported by damon).

	* gtk/gtkdnd.c: make the cursor and icon data _unsigned_ char,
	since we provide unsigned data anyways.

Thu Sep 16 21:32:01 1999  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtktooltips.c (gtk_tooltips_set_tip): Delay
	the call to gtk_tooltips_layout_text() until later.

	* gtk/gtktooltips.c (gtk_tooltips_draw_tips):
	Call gtk_widget_ensure_style() before using the style.

Wed Sep 15 02:52:19 1999  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtkwidget.c (gtk_widget_event): Added workaround
	for old widgets that don't propagate draws to all
	children. (Namely gnome-dock for gnome-libs <= 1.0.16)

Tue Sep 14 19:22:19 1999  Tim Janik  <timj@gtk.org>

	* gtk/gtkwidget.c (gtk_widget_queue_resize): don't queue the parent
	for a redraw but just the widget that requested the resize.

Tue Sep 14 18:29:47 1999  Tim Janik  <timj@gtk.org>

	* gtk/gtkcontainer.c: added new widget level method
	gtk_container_set_reallocate_redraws() and a GtkContainer flag
	reallocate_redraws : 1 to reflect the setting, exported this through
	the argument system as a boolean ::reallocate_redraws.

	* gtk/gtkwidget.c (gtk_widget_size_allocate): when queueing redraws
	on the widget because the allocation changes, do so as well for
	widget->parent if the parent has reallocate_redraws set to TRUE.
	with that containers requesting reallocation redraws get automatically
	redrawn if their children changed allocation (this unfortunately
	affects also other children that didn't change allocation, but we
	cannot work around that before 1.3).

Tue Sep 14 18:23:01 1999  Tim Janik  <timj@gtk.org>

	* gtk/gtkwidget.c (gtk_widget_idle_draw): only emit ::draw if width
	_and_ height are >0 (not _or_).

	* gtk/gtktable.c (gtk_table_remove): use gtk_widget_queue_resize()
	instead of gtk_container_queue_resize(), which is a core gtk internal
	function (must have been on crack when i queued that).

	* gtk/gtkprivate.h: added new private flag GTK_FULLDRAW_PENDING, so
	we can check more reliably if we want to discard expose events.
	* gtk/gtkwidget.c: added setting/unsetting of the GTK_FULLDRAW_PENDING
	flag.

	* gtk/gtkwidget.c (gtk_widget_event): don't discard synthesized exposes,
	we simply trust these events. for deciding whether to discard exposes,
	check GTK_FULLDRAW_PENDING instead of RESIZE_PENDING.

Mon Sep 13 15:01:21 1999  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtkwidget.c (gtk_widget_queue_clear_area): Ignore
	queues of areas that are completely off screen.

	* gtk/gtkwidget.c (gtk_widget_idle_draw): Fix broken
	logic for handleboxes.

	* gtk/gtkwidget.c (gtk_widget_queue_draw_data): Add santity
	check on width/height.

Mon Sep 13 02:22:47 1999  Tim Janik  <timj@gtk.org>

	* gtk/Makefile.am: backed out Raja's recent VPATH build "improvements",
	we are fine with using $@ the way we do (if we actually encounter
	brokeness with $@ in VPATH builds because of additional path prefixes,
	we need to use $(@F) actually).

Mon Sep 13 01:34:53 1999  Tim Janik  <timj@gtk.org>

	* gtk/gtksignal.c: renamed two variables, hopefully didn't introduce
	short lived bugs, that would allow language bindings to do surgeries
	to our guts.

Fri Sep 10 15:22:50 1999  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtkwindow.c (gtk_window_size_allocate): Fix typo
	where comparison was being done against an uninitialized
	value causing intermittant results depending on
	compiler flags. Also make it clearer that we aren't
	ever initializing the child as 0x0 (though this will
	be caught in gtk_widget_size_allocate())

Fri Sep 10 10:06:56 1999  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtkwindow.c (gtk_window_set_transient_for): Move
	gtk_window_unset_transient_for() call after we do checks
	involving the old transient parent.
	[ From Lance Capser <lmc@cyberhighway.net> ]

1999-09-07  Raja R Harinath  <harinath@cs.umn.edu>

	* gtk/Makefile.am (gtk.defs): Go back to using `touch' to create
	an empty file.

Mon Sep  6 00:11:56 1999  Lars Hamann  <lars@gtk.org>

	* gtk/gtkctree.c (gtk_ctree_is_ancestor): return FALSE if node has
	no children. (Reported by: Chris Rogers <gandalf@pobox.com>)

1999-09-03  Raja R Harinath  <harinath@cs.umn.edu>

	* gtk/Makefile.am (gen_sources): Improve VPATH builds.
	`$@' is valid only in the build dir, not after we've done
	`cd $srcdir'.  Also use `test -f' instead of less portable
	`test -e'.

Fri Sep  3 15:59:56 1999  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtktext.c (correct_cache_insert): Rewrite
	 for simplicity, and hopefully correctness.
	 (Fixes bug #1322, which was a segfault when
	  on some insertions with the properties around
	  the insertion set up just wrong.)

	* gtk/gtktext.c (gtk_text_adjustment): When we receive
	 a "changed" signal, clamp the new value to the adjustment
	 bounds to avoid segfaulting if someone tries to change
	 the adjustment to a bogus value. (Bug #1795)

Thu Sep  2 16:33:59 1999  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtkmain.c: Ignore unexpected destroy notifies
	for children, for toplevel windows handle them
	like delete_event.

	* gtk/gtkplug.c: Add an unrealize handler so that
	we unref plug->socket_window when we are done
	with it.

Fri Sep  3 14:52:54 1999  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtktext.c (clear_area): Fix stupid signedness
	 problem that was causing background to sometimes
	 be misaligned.

Fri Sep  3 12:26:33 1999  Owen Taylor  <otaylor@redhat.com>

	[ Fixes pointed out by Ettore Perazzoli <ettore@comm2000.it> ]

	* gtk/gtkmenu.c (gtk_menu_position): Make
	 sure we never position menus with negative x, y,
	 since gtk_widget_set_uposition() can't handle that.

	* gtk/gtkmenuitem.c (gtk_menu_item_position_menu):
	 Modify the positioning code a bit so that we always
	 put the top-left corner onscreen. (This is for
	 UI reasons, gtk_menu_position() now takes care of
	 gtk_widet_set_uposition() brokeness.)

Fri Sep  3 03:06:30 1999  Tim Janik  <timj@gtk.org>

	* gtk/Makefile.am: fixed up things for -jx, x > 1.

Sun Sep  5 08:48:51 1999  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtkwidget.c (gtk_widget_modify_style): Ref the
	  RC style that is passed in. The lack of the ref
	  before was a bug. If people worked around this
	  bug, this will introduce a slight memory leak
	  in their code. The code should typically look like:

	    rc_style = gtk_rc_style_new ();
	    [...]
	    gtk_widget_modify_style (widget, rc_style);
	    gtk_rc_style_unref (rc_style);

	* gtk/gtkwidget.c (gtk_widget_modify_style): Reset
	  the style if it was already set.

	* gtk/gtkwidget.c (gtk_widget_set_name): Only set the
	  style if it was set before.

Thu Sep  2 19:02:37 1999  Owen Taylor  <otaylor@redhat.com>

	* gtk/testgtk.c (main): Add a check to see if we
	  are being run from the correct directory and
	  to quit nicely if we are not.

	* gtk/gtkrc.c (gtk_rc_slist_remove_all): Make function
	  static.

Thu Sep  2 23:00:03 1999  Tim Janik  <timj@gtk.org>

	* gtk/gtkenums.h (GtkWindowPosition): added GTK_WIN_POS_CENTER_ALWAYS.

	* gtk/gtkwindow.c:
	queue resizes unconditionally (gtk_widget_queue_resize will figure
	what to do if the window is not realized).
	(gtk_window_move_resize): only recenter the window
	for GTK_WIN_POS_CENTER_ALWAYS.
	(gtk_window_compute_reposition): handle GTK_WIN_POS_CENTER_ALWAYS in
	the same way as GTK_WIN_POS_CENTER.

Thu Sep  2 22:39:27 1999  Tim Janik  <timj@gtk.org>

	* gtk/gtkwindow.c (gtk_window_reposition): check for the last position
	with (!(info->last_flags & GDK_HINT_POS)) instead of
	(!info->last_flags & GDK_HINT_POS).

	* gtk/gtkwindow.c (gtk_window_move_resize): constrain new_width and
	new_height unconditionally, because we use these values even if
	!default_size_changed && !hints_changed.
	comented the (default_size_changed || hints_changed) case with
	respect to resize rejects from the window manager.

	* gtk/gtkwindow.c (gtk_window_move_resize): save info->last values
	in the zvt condition hack, since this includes the window hints, set
	the hints after the handling_resize case.

	* gtk/gtkwindow.c (gtk_window_show): constrain the default size that a
	window is initially shown with to the geometry.

Thu Sep  2 07:38:56 1999  Tim Janik  <timj@gtk.org>

	* gtk/gtkwindow.c (gtk_window_move_resize):
	s/size_changed/default_size_changed/g so i know what's
	really going on (frying brain on smaller flame now).

Thu Sep  2 05:47:47 1999  Tim Janik  <timj@gtk.org>

	* gtk/gtkwindow.c (gtk_window_move_resize): queue a new resize if
	we have size_changed upon handling_resize. this is a gross
	workaround for the broken zvt widget and should be removed in
	1.3 again (search for FIXME).
	Owen provided an accurate comment for this:

        /* We could be here for two reasons
         *  1) We coincidentally got a resize while handling
         *     another resize.
         *  2) Our computation of size_changed was completely
         *     screwed up, probably because one of our children
         *     is broken. It's probably a zvt widget.
         *
         * For 1), we could just go ahead and ask for the
         * new size right now, but doing that for 2)
         * might well be fighting the user (and can even
         * trigger a loop). Since we really don't want to
         * do that, we requeue a resize in hopes that
         * by the time it gets handled, the child has seen
         * the light and is willing to go along with the
         * new size. (this happens for the zvt widget, since
         * the size_allocate() above will have stored the
         * requisition corresponding to the new size in the
         * zvt widget)
         *
         * This doesn't buy us anything for 1), but it shouldn't
         * hurt us too badly, since it is what would have
         * happened if we had gotten the configure event before
         * the new size had been set.
         */

Wed Sep  1 20:46:11 1999  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtkrc.c: deal properly with the fact that RC
	  style lists may include rc styles more than once.

	* gtk/gtkrc.c (gtk_rc_append_pixmap_path): Removed
	  unused static function.

	* gtk/gtkrc.c (gtk_rc_find_pixmap_in_path): Keep a
	  stack of directories of RC files currently being
	  parsed and implicitely add them to pixmap path.

	  This fixes a bug where the directory would get
	  appended then overwritten by pixmap_path declarations.

	  (bug #1462, from Peter Wainright <prw@wainpr.demon.co.uk>)

	* gtk/gtkthemes.c (gtk_theme_engine_unref): Call
	  theme's exit function. (Patch from Peter Wainwright,
	  bug #1454)

	* gtk/gtkradiomenuitem.c (gtk_radio_menu_item_destroy):
	  Add a destroy() handler to take care of removing
	  group for menu item. (Fixes bug #1197)

	* gtk/gtkwidget.c (gtk_widget_size_request): Fixed thinko
	  in warning message.

Wed Sep  1 21:27:42 1999  Tim Janik  <timj@gtk.org>

	* gtk/gtkwindow.c (gtk_window_move_resize): don't require a server
	roundtrip to figure window's width and height, since we know that
	anyways from widget->allocation.

Wed Sep  1 12:37:44 1999  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtkwindow.c (gtk_window_move_resize): Compute
	  the hints after we request the new size.

Wed Sep  1 10:38:37 1999  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtkwindow.c (gtk_window_compute_hints): Removed
	  GTK_WIDGET_REALIZED() assertion - we can compute the
	  hints before we are realized.

	* gtk/gtkwindow.c (gtk_window_move_resize): Reorder
	  hint changing so that we have a value of hints_changed
	  when we decide whether to constrain the window size.

	* gtk/gtkwindow.c (gtk_window_move_resize): Spelling fix.

	* gtk/gtkwindow.c (gtk_window_constrain_size): cleanups,
	change back to G_MAXINT.

Wed Sep  1 06:54:59 1999  Tim Janik  <timj@gtk.org>

	* gtk/gtkwindow.c (gtk_window_get_geometry_info): zero initialize
	new GtkWindowGeometryInfo, so fields like GdkGeometry geometry
	contain uncluttered values.
	(gtk_window_compute_hints): simply assert that window is realized
	and that geometry_info is valid, since we rely on this anyways.
	(gtk_window_constrain_size): major cleanups to the code.
	if (flags & GDK_HINT_BASE_SIZE) use geometry's base width and height
	for the base size, instead of the minimums. use 32767 as max width
	and height (like in gtkwindow.c) instead of G_MAXINT.

Wed Sep  1 04:41:25 1999  Tim Janik  <timj@gtk.org>

	* cleaned up the GtkContainer.need_resize flag handling mess, we
	only need to force resize requests when we were prematurely
	realized, or our widget tree was modified when we were temporarily
	hidden. handling these cases directly upon showing the window (i.e.
	while the GdkWindow is still unmapped) avoids the need to wait for
	a configure event response and therefore makes the GUI more snappier
	and avoids blank windows during the roundtrip.

	* gtk/gtkwidget.c:
	(gtk_widget_hide):
	(gtk_widget_show): don't queue resizes on toplevels, they know how
	to deal with matters.

	* gtk/gtkcontainer.c (gtk_container_queue_resize): set the ->need_resize
	flag directly for not visible resize containers and spare us unecessary
	signal emissions.

	* gtk/gtkwindow.c:
	(gtk_window_realize): if we need to enforce premature size allocation,
	queue a container resize so we are correctly resized later on.
	(gtk_window_init):
	(gtk_window_size_request):
	don't freak around with the ->need_resize flag,
	gtk_container_queue_resize() will care about that.
	(gtk_window_show):
	handle initial resizing issues here, we can handle matters better in
	this place, especially since we know that our GdkWindow is still
	unmapped.
	(gtk_window_move_resize):
	don't care about ->need_resize at all.
	handle size changes properly that occoured while we waited for a
	configure event.

Tue Aug 31 15:58:46 1999  Owen Taylor  <otaylor@redhat.com>

        * gtk/gtkwidget.c (gtk_widget_set_uposition):
        * gtk/gtkwindow.[hc] (gtk_window_reposition):
        Move the hint setting code from gtk_widget_set_uposition
        to here; set the hints so that we respect any previously
        set geometry hints.

        * gtk/gtkwindow.c (gtk_window_compute_reposition): Don't
        change the window hints here or move the window here,
        let that happen in gtk_window_move_resize().

Tue Aug 31 06:58:52 1999  Tim Janik  <timj@gtk.org>

	* gtk/gtkwidget.c (gtk_widget_event): when discarding exposes due
	to already queued resizes (and therefore redraws) on a widget, check
	its anchestry as well.

	* gtk/gtkcontainer.c:
	(gtk_container_queue_resize): clear resize widgets for resize
	containers before aborting prematurely. this is especially important
	for toplevels which may need imemdiate processing or their resize
	handler to be queued.
	(gtk_container_dequeue_resize_handler): added new internal function for
	gtkwindow.c.

	* gtk/gtkwindow.c (gtk_window_move_resize): if we are resizing due to a
	configure event, take possible changes in window position into account
	as well.
	if we request a new window size, queue up a resize handler that will
	last until the configure event response arrives.
	combined the ->need_resize case (initial show) with the general size
	(hints) changed case and added even more comments.
	if !auto_shrink, only revert to the old allocation if the new size
	is smaller than the current allocation.

Tue Aug 31 11:55:20 1999  Owen Taylor  <otaylor@redhat.com>

        * gtk/gtkwindow.c (gtk_window_set_arg, gtk_window_set_policy,
                           gtk_window_set_geometry_hints
                           gtk_window_set_default_size):
        When hints are set, queue a resize so that the hints will
        be eventually reset on the toplevel.

        * gtk/gtkwindow.c (gtk_window_show): Use
        gtk_window_compute_default_size(). Clear the need_resize flag
        on the initail map so that we don't unnecessarily trigger the
        resize code.

        * gtk/gtkwindow.c (gtk_window_move_resize): Split apart
        into separate functions. Compare the hints we are setting
        with what we set last time so that we can accurately
        tell when we need to reset the hints.

        * gtk/gtkwindow.c (gtk_window_compute_default_size): New
        function to figure out the size from requisition
        and default_size.

        * gtk/gtkwindow.c (gtk_window_constrain_size): Function
        from fvwm to constrain a size to the geometry hints.

        * gtk/gtkwindow.c (gtk_window_compare_hints): New function
        to compare two sets of geometry hints.

        * gtk/gtkwindow.c (gtk_window_compute_hints): Renamed
        from gtk_window_set_hints(), just compute the hints,
        don't set them.

        * gtk/gtkwindow.c (gtk_window_compute_reposition): Move
        code from gtk_window_move_resize() to separate function,
        rationalize a bit.

Tue Aug 31 13:05:03 1999  Owen Taylor  <otaylor@redhat.com>

	* gtkrc.h: Move the ref_count member out of the GtkRcStyle
	structure into a new private structure.

	* gtkrc.c: Split GtkRcStyle into public/private.
	In the private part, add a list of pointers to the
	RcStyle lists this RcStyle participates in.

	* gtkrc.c: When a RcStyle is free, remove all
	lists referencing it from the
	realized_style_ht hash, and free those lists.

	* gtk/gtkrc.c (gtk_rc_clear_styles): Don't call
	gtk_rc_init(), since that adds the default styles
	to the list of parsed RC files again.

	* gtk/gtkrc.c: Use gtk_rc_style_find() consistently.

Thu Aug 26 14:14:42 1999  Tim Janik  <timj@gtk.org>

	* gtk/gtkwidget.c (gtk_widget_size_allocate): reactivated the sanity
	checks that ensure that a widget's allocation is at least 1 in width
	and height. (GNOME note: this doesn't affect old panel code anymore,
	because GtkSocket will request width and height of at least 1 since
	Fri Jul 23).

	* gtk/gtkwindow.c (gtk_window_realize): if the widget hasn't been
	allocated yet (happens if the user realizes the window prematurely),
	size request and allocate it.
	(gtk_window_size_allocate): guard against guint underflows.

Wed Aug 25 19:01:36 1999  Lars Hamann  <lars@gtk.org>

	* gtk/Makefile.am (gtk_built_sources): reordered stamp-gtk.defs
 	in gtk_built_sources, so gtk.defs gets built prior to all other
 	sources.

Mon Aug 23 19:11:17 1999  Tim Janik  <timj@gtk.org>

	* gtk/Makefile.am:
	invoke indent on gtkmarshal.*.
	rewrote source generation rules, use COPYING as oldest source tag for
	a piggyback rule to generate all sources from (don't touch it ;).
	major cleanups, strip spaces on build rules for GNU Make.

	* gtk/genmarshal.pl: don't operate on hardcoded filenames but take
	source and target files from commandline arguments. don't invoke indent.

Sat Aug 21 14:07:36 1999  Lars Hamann  <lars@gtk.org>

	* gtk/gtknotebook.c (gtk_notebook_real_switch_page): queue_resize

	(gtk_notebook_pages_allocate): don't map not visible tab_labels,
	show them instead.

Wed Aug 18 09:20:10 1999  Tim Janik  <timj@gtk.org>

	* gtk/gtkwindow.c:
	we use window->need_resize from configure_event now, to indicate that
	the gtkwindow should keep its allocation (e.g. because the user resized
	the window through window manager handles). resize_count is now reliably
	used to figure whether we got the allocation we requested from the
	window manager.
	configure events get queued as resizes now, the real stuff (size
	computation and allocation) now only goes on in gtk_window_move_resize().
	GtkWindow's requisition now contains its *real* requisition (like all
	other widgets), *not* taking usize into account.
	geometry_info->last_{width|height} is now updated from set_hints() only
	so it always contains the last hints we set for the window manager.
	made some event handlers return TRUE instead of FALSE.
	the overall code should be much more straight forward now, and the
	significant code portions are accompanied by comments now.
	(gtk_window_set_hints):
	removed requisition argument and made it
	fetch the requisition through gtk_widget_get_child_requisition.
	we also don't move the gdkwindow here anymore, gtk_window_move_resize()
	does that now.
	(gtk_window_show):
	ensure that the widget is realized before calling
	gtk_container_check_resize() (and thus gtk_window_move_resize()), also
	ensure that we got properly size requested and allocated before
	realization.
	(gtk_window_configure_event):
	ignore plain window moves, or reallocate the widget tree through the
	resize queue otherwise.
	(gtk_window_move_resize):
	mostly rewrote this function to figure window manager hints more
	reliably, coalesce window moves and resizes to reduce configure events
	and do actuall size allocations.

Tue Aug 17 07:43:04 1999  Tim Janik  <timj@gtk.org>

	* gtk/gtkwidget.c (gtk_widget_event): discard expose events for widgets
	that have a resize pending, because a redraw is already queued for them.

	* gtk/gtkcontainer.c: removed ugly connect_to ::size_allocate signal
	hack to clear resize_widgets.

	* gtk/gtkwidget.c (gtk_widget_size_allocate): call clear_resize_widgets
	for resize containers prior to size allocation. (this is also a bit
	ugly, but avoids side effects for stopped emissions and is thus more
	reliable).
	(gtk_widget_unparent): removed disconnect call for clear_resize_widgets.

	* gtk/gtktooltips.c (gtk_tooltips_paint_window): renamed this
	function from gtk_tooltips_expose, as we connect to ::expose_event
	*and* ::draw now.

1999-08-18  Federico Mena Quintero  <federico@redhat.com>

	* gtk/gtkselection.c (gtk_target_list_ref): Added missing sanity
	checks.
	(gtk_target_list_unref): Likewise.

	Prevent the trivial leak of information of allowing
	word motion when the entry is not visible.

Tue Aug 17 10:28:52 1999  Owen Taylor  <otaylor@redhat.com>

	tree->view_lines.
	(gtk-guy-990611-3.patch: Guy Harris <guy@netapp.com>)

	(gtk-guy-990611-2.patch: Guy Harris <guy@netapp.com>)

1999-07-30  Raja R Harinath  <harinath@cs.umn.edu>

	* gtk/Makefile.am (stamp-m): Don't `mv' from builddir to srcdir,
	use `cp' followed by `rm' (the `rm' was already there).

July 30, 1999 Elliot Lee <sopwith@redhat.com>

	* configure.in: Fix autoconf warnings about cross compilation by
	trying to provide sane defaults for AC_TRY_RUN.
	* gtk/Makefile.am: If we refer to gtkmarshal.[ch] in $(srcdir),
	put them into $(srcdir) when generated. Also add a dependency of
	gtksignal.h on gtkmarshal.h for -j builds.
	* gtk/gtk(dnd,style,gamma).c: Minor warning fixes.

	* gtk/gtksocket.c (gtk_socket_size_request): asure that the requested
	width and height are always >0 (owen).

Fri Jul 23 00:00:47 1999  Tim Janik  <timj@gtk.org>

	* gtk/gtkwidget.c (gtk_widget_size_allocate): backed out my recent
	change that assured that a widget's allocated with and height are
	always >1, since this breaks *buggy* panel code. unfortunately this
	back-breaks the gimp's color selector.

	* gtk/gtkdrawingarea.c (gtk_drawing_area_size_allocate): asure that our
	allocation is always >0 in width and height, before sending the
	configure event; this is a *gross* hack to get the gimp back to work.

	* marked both cases with TODO-1.3

Wed Jul 21 15:47:39 1999  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtktext.c: Don't display wrap indicators when

	* gtk/gtkitemfactory.c (gtk_item_factory_create_item): special case
	option menus here as they are not derived from menu shell, assure that
	the option menu has a menu we can add items to.

Tue Jul 20 23:29:48 1999  Tim Janik  <timj@gtk.org>

	* gtk/gtknotebook.c (gtk_notebook_page_allocate): convert allocation->
	width/height to (gint) before calculations and check against < 0 to
	avoid guint wraparounds.

Sun Jul 18 00:35:49 1999  Tim Janik  <timj@gtk.org>

	* gtk/gtkwidget.c (gtk_widget_size_allocate): ensure that the allocated
	width and height is never zero. sanity check both dimensions against
	32767 and issue a warning if the allocation is greater than that.

Wed Jul  7 15:03:30 1999  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtkmain.c (gtk_events_pending): Unlock around call

	GTK+ lock to process events.

Thu Jul  1 15:01:55 1999  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtkwindow.c
	- Regularize with the rest of GTK+ by making widget->requisition
	  not reflect the set_usize()
	- Always recompute geometry hints, then check if they
	  changed before sending them to the X server. The
	  previous checks for changes would fail in a number
	  of circumstances.

        * gtk/gtklabel.c (gtk_label_set_pattern):
        (gtk_label_set_justify):
        (gtk_label_set_line_wrap):
        don't bother invoking queue_clear, the reallocation does
        that for us, always free_words so the upcoming resize will
        relayout the label's contents.

	* gtk/gtktree (drag_dest_cell)
	(gtk_ctree_drag_data_received) (gtk_ctree_drag_motion): likewise.
	(Bug #1129)

Wed Apr 21 21:26:11 1999  Tim Janik  <timj@gtk.org>

	* gtk/gtkitemfactory.c (gtk_item_factory_init): properly initialize
	translate_* fields.
	(gtk_item_factory_finalize): invoke translate_notify independant from
	translate_data.
	(gtk_item_factory_set_translate_func): likewise.

Thu Apr  8 20:10:33 1999  Tim Janik  <timj@gtk.org>

	* gtk/gtkentry.c (gtk_entry_key_press): use gtk_widget_activate()
	rather than emit_by_name.

	on the widget across multiple signal emissions.
	(gtk_editable_delete_text): same here.
	(gtk_editable_class_init): set widget_class->activate_signal after
	editable_signals[ACTIVATE] has been created.

Wed Apr  7 22:59:47 1999  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtkpaned.c (gtk_paned_set_position): Don't clamp
	position here prematurely -- we might not have the
	right ->min_position and ->max_position yet.

Tue Apr  6 16:38:51 1999  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtkselection.c gdk/gdkselection.c: (gtk_selection_request):

	dies, we survive.

	* gtk/gtkselection.c (gtk_selection_notify): Clean

	Motif onto a proxy window that is rejecting the
	drop.

Sat Mar 27 23:32:13 1999  Tim Janik  <timj@gtk.org>

	* gtk/gtkarg.[hc]: added functions from GLE, gtk_arg_reset() to free
	the value and reset type to GTK_TYPE_INVALID, and gtk_arg_values_equal()
	to compare two argument values. added gtk_arg_to_valueloc() to set a
	variable from an arg through its location (pointer).

	* gtk/gtkobject.[hc]: implemented gtk_object_get() in terms of
	gtk_object_arg_get() and gtk_arg_to_valueloc(), floats are collected
	as gfloat*, uchars are collected as guchar*, ints are collected as
	gint*, etc...

Mon Mar 29 17:45:47 1999  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtkaccelgroup.c gtk/gtkgtkbindings.c:
	Include <string.h> instead of <strings.h>.

	* gtk/gtkstyle.c: Fix double include of gtkthemes.h
	(actually, a lot more duplicate includes occur if
	 you trace through the sequence of #include's)
	gtk-jbb-990320-0: John Bley, jbb6@acpub.duke.edu

Mon Mar 29 17:02:58 1999  Owen Taylor  <otaylor@redhat.com>

        Patches from Akira Higuchi <a-higuti@math.sci.hokudai.ac.jp>
	gtk-a-higuti-990322-[0-3]

	* configure.in: Fix confusion between GTK_LOCALE_[C]FLAGS
	that was causing -DX_LOCALE not	to work.

	* gtk/gtkrc.c (gtk_rc_init):
	X_LOCALE will never have LC_MESSAGES defined

Thu Mar 25 12:38:31 1999  Tim Janik  <timj@gtk.org>

	* gtk/gtkrc.c (gtk_rc_append_default_module_path): get $HOME from
	g_get_home_dir() (gtk-pmc-990123-0.patch.gz).

	* gtk/gtkwindow.c (gtk_window_key_press_event): feature keypad up/down/
	left/right as well (gtk-michael-980726-0.patch.gz).

	* gtk/gtklabel.[hc]: bunch of miscellaneous cleanups, such as s/0/NULL/
	for pointer values, use gchar instead of char. fixed uline allocation
	leaks, changed the allocation pattern so we use G_ALLOC_AND_FREE mem
	chunks instead of G_ALLOC_ONLY.
	(gtk_label_size_request): always alter requisition as passed and leave
	widget->requisition alone.
	(gtk_label_set_text): allow NULL strings.
	(gtk_label_new): likewise.

Wed Mar 24 09:24:03 1999  Tim Janik  <timj@gtk.org>

	* gtk/gtkdrawingarea.[hc]: type/macro fixups.

Mon Mar 22 05:51:34 1999  Tim Janik  <timj@gtk.org>

	* gtk/gtkbin.c (gtk_bin_draw): only redraw children that are visible
	*and* mapped (i.e. drawable).
	(gtk_bin_expose): only send exposes to drawable children.

	* gtk/gtkbox.c (gtk_box_draw): only redraw children that are drawable.
	(gtk_box_expose): only send exposes to drawable children.

	* gtk/gtkhscale.c (gtk_hscale_draw):
	* gtk/gtkvscale.c (gtk_vscale_draw):
	hm, this is an ugly one. we first compute the size of our trough area
	here (window relative) and then check intersection with the draw_area
	which is parent relative because we're a NO_WINDOW widget, so we need
	to offset the trough area by allocation.x and allocation.y before the
	check. (this must not be done for the background area though, since
	that's already computed parent relative).

Mon Mar 22 00:41:39 1999  Lars Hamann  <lars@gtk.org>

	* gtk/gtkclist.c (gtk_clist_unrealize): unmap clist if neccessary,
	unrealize title buttons.

Fri Mar 19 00:00:22 1999  Lars Hamann  <lars@gtk.org>

	* gtk/gtkclist.c (gtk_clist_column_title_passive)
	(gtk_clist_column_title_active):
	only connect/disconnect to GtkWidgetClass::event to block mouse events.

	* gtk/gtkclist.c (vertical_timeout) (horizontal_timeout):
	zero initialize event, removed superfluous gdk_window_get_pointer call

	* gtk/gtklist.c (gtk_list_vertical_timeout)
	(gtk_list_horizontal_timeout): removed superfluous
 	gdk_window_get_pointer call

Wed Mar 17 09:00:00 1999  Tim Janik  <timj@gtk.org>

	* plugging problems reported by "Bruce Mitchener, Jr."
	<bruce@puremagic.com> due to a purify session.

	* gtk/gtkstyle.c:
	(gtk_style_ref):
	(gtk_style_unref): assert ref_count to be > 0.

	* gtk/gtkclist.c (gtk_clist_set_cell_style): { 0 } initilaize
	the requisition.
	(gtk_clist_set_shift): likewise.

	* gtk/gtklayout.c: introduce gtk_layout_finalize() to unref the
	adjustments.

	* gtk/gtklist.c (gtk_list_horizontal_timeout): zero initialize the
	event before sending it and set send_event to TRUE (which needs to
	be done for *all* synthesized events).
	(gtk_list_vertical_timeout): likewise.

	* gtk/gtktipsquery.c (gtk_tips_query_destroy): plug small memory
	leaks.

	* gtk/gtkdrawingarea.c (gtk_drawing_area_send_configure): set send_event
	to TRUE when synthesizing events.
