1960 * Sends an event to a widget, propagating the event to parent widgets
1961 * if the event remains unhandled. Events received by GTK+ from GDK
1962 * normally begin in gtk_main_do_event(). Depending on the type of
1963 * event, existence of modal dialogs, grabs, etc., the event may be
1964 * propagated; if so, this function is used. gtk_propagate_event()
1965 * calls gtk_widget_event() on each widget it decides to send the
1966 * event to. So gtk_widget_event() is the lowest-level function; it
1967 * simply emits the "event" and possibly an event-specific signal on a
1968 * widget. gtk_propagate_event() is a bit higher-level, and
1969 * gtk_main_do_event() is the highest level.
1971 * All that said, you most likely don't want to use any of these
1972 * functions; synthesizing events is rarely needed. Consider asking on
1973 * the mailing list for better ways to achieve your goals. For
1974 * example, use gdk_window_invalidate_rect() or
1975 * gtk_widget_queue_draw() instead of making up expose events.
