Gtk.Window.prototype.propagate_key_event

function propagate_key_event(event:Gdk.EventKey):Boolean {
    // Gjs wrapper for gtk_window_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.
