gtkPropagateEvent: gtkPropagateEvent

Description

Sends an event to a widget, propagating the event to parent widgets if the event remains unhandled. Events received by GTK+ from GDK normally begin in gtkMainDoEvent. Depending on the type of event, existence of modal dialogs, grabs, etc., the event may be propagated; if so, this function is used. gtkPropagateEvent calls gtkWidgetEvent on each widget it decides to send the event to. So gtkWidgetEvent is the lowest-level function; it simply emits the "event" and possibly an event-specific signal on a widget. gtkPropagateEvent is a bit higher-level, and gtkMainDoEvent is the highest level.

Usage

gtkPropagateEvent(object, event)

Arguments

object

a GtkWidget

event

an event

Details

All that said, you most likely don't want to use any of these functions; synthesizing events is rarely needed. Consider asking on the mailing list for better ways to achieve your goals. For example, use gdkWindowInvalidateRect or gtkWidgetQueueDraw instead of making up expose events.
