propagate_key_event

Propagate a key press or release event to the focus widget and up the focus container chain until a widget handles event.

This is normally called by the default key_press_event and key_release_event handlers for toplevel windows, however in some cases it may be useful to call this directly when overriding the standard key handling for a toplevel window.

Parameters:

this	a Window
event	a EventKey

Returns:

true if a widget in the focus chain handled the event.
