Document expose event->region change and that gtk_widget_event doesn't

2001-03-09  Alexander Larsson  <alexl@redhat.com>

	* docs/Changes-2.0.txt:
	Document expose event->region change and that gtk_widget_event
	doesn't allow passing expose events.

	* gdk/gdkevents.h:
	Add region to expose event.

	* gdk/gdkevents.c:
	Handle event->region in gdk_event_copy() and gdk_event_free().

	* gdk/gdkwindow.c (gdk_window_process_updates_internal):
	Generate expose_event->region when creating expose events.

	* gdk/x11/gdkevents-x11.c:
	Generate expose events with regions when translating X events.

	* gtk/gtkcontainer.[ch]:
	Default expose handler that propagates expose events to NO_WINDOW
	children. New function gtk_container_propagate_expose()

	* gtk/gtkwidget.[ch]:
	Moved gtk_widget_event implementation to gtk_widget_event_internal.
	gtk_widget_event calls gtk_widget_event_internal but doesn't allow
	expose events. New function gtk_widget_send_expose() to send expose
	events. New function gtk_widget_region_intersect() to calculate
	window/region intersections.

	* gtk/gtkmain.c (gtk_main_do_event):
	Use gdk_window_begin_paint_region() instead of gdk_window_begin_paint_rect().
	Use gtk_widget_send_expose() to send expose events.

	* gtk/gtkbin.c:
	* gtk/gtkbox.c:
	* gtk/gtkfixed.c:
	* gtk/gtkimagemenuitem.c:
	* gtk/gtklist.c:
	* gtk/gtkpacker.c:
	* gtk/gtktable.c:
	* gtk/gtktree.c:
	Remove expose handler, using the default container implementation
	instead.

	* gtk/gtkbutton.c:
	* gtk/gtkcheckbutton.c:
	* gtk/gtkeventbox.c:
	* gtk/gtkfixed.c:
	* gtk/gtkhandlebox.c:
	* gtk/gtklayout.c:
	* gtk/gtklistitem.c:
	* gtk/gtkmenu.c:
	* gtk/gtkmenubar.c:
	* gtk/gtkmenuitem.c:
	* gtk/gtknotebook.c:
	* gtk/gtkoptionmenu.c:
	* gtk/gtkpaned.c:
	* gtk/gtkscrolledwindow.c:
	* gtk/gtktogglebutton.c:
	* gtk/gtktoolbar.c:
	* gtk/gtktreeitem.c:
	* gtk/gtkviewport.c:
	Chain expose handler to parent class handler. Use
	gtk_container_propagate_expose() to propagate exposes.

	* gtk/gtkclist.c (check_exposures):
	* gtk/gtktext.c (process_exposes):
	Use gtk_widget_send_expose instead of gtk_widget_event.
