Fix event filter handling. If an event filter (global, client message

Browse Source 
2005-03-30  Tor Lillqvist  <tml@novell.com>

	* gdk/win32/gdkevents-win32.c (gdk_event_translate): Fix event
	filter handling. If an event filter (global, client message
	filter, of window-specific) returns GDK_FILTER_CONTINUE,
	continue as if nothing happened. If it returns
	GDK_FILTER_REMOVE or GDK_FILTER_TRANSLATE, return TRUE from
	gdk_event_translate() which means that DefWindowProc() will
	not be called.
	(gdk_event_translate): Fix client message handling. Append a
	GDK_CLIENT_EVENT unless there is a filter that matches and returns
	something other than GDK_FILTER_CONTINUE. (#135552)
