gtkPropagateEvent {RGtk2} | R Documentation

## 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.
