gtk/gdk/x11/gdkevents-x11.c
Havoc Pennington f37a0627fc fix a typo. 
2001-08-07  Havoc Pennington  <hp@pobox.com>

	* gtk/gtkfilesel.c (open_ref_dir): fix a typo.

	* gtk/gtkplug.c (gtk_plug_init): remove setting of auto_shrink;
	some fixage is needed here, but nothing simple. Owen understands
	it. ;-)

        * gtk/gtkwindow.h, gtk/gtkwindow.c: Rework code and API for window
	sizing and positioning.  Also, fix bug in compute_geometry_hints
	(width/height confusion for setting min size).
	(gtk_window_move): new function
	(gtk_window_resize): new function
	(gtk_window_get_size): new function
	(gtk_window_get_position): new function
	(gtk_window_parse_geometry): new function

 	* gtk/gtkwidget.c (gtk_widget_set_size_request): new function
 	(gtk_widget_get_size_request): new function
 	(gtk_widget_get_usize): delete, that was a short-lived function
 	;-)
 	(gtk_widget_set_usize): deprecate
 	(gtk_widget_set_uposition): deprecate, make it a trivial
	gtk_window_move() wrapper
	(gtk_widget_class_init): remove x/y/width/height properties,
	add width_request height_request

        * demos/*: update to avoid deprecated functions

	* gtk/gtklayout.c: add x/y child properties

	* gtk/gtkfixed.c: add x/y child properties, and get rid of
	uses of "gint16"

	* tests/testgtk.c (create_window_sizing): lots of tweaks to window
	sizing test

	* gdk/x11/gdkevents-x11.c (gdk_event_translate): Ensure that
	configure events on toplevel windows are always in root window
	coordinates, following ICCCM spec that all synthetic events
	are in root window coords already, while real events are
	in parent window coords. Previously the code assumed that
	coords of 0,0 were parent window coords, which was
	really broken.

 	* gtk/gtkcontainer.c (gtk_container_get_focus_chain): fix
 	warning

 	* gdk/gdkwindow.h (GdkWindowHints): add GDK_HINT_USER_POS
 	and GDK_HINT_USER_SIZE so we can set USSize and USPosition
 	hints in gtk_window_parse_geometry()

 	* gdk/x11/gdkwindow-x11.c (gdk_window_set_geometry_hints): support
 	new USER_POS USER_SIZE hints
