+as your EVT\_MENU entries, events from the toolbar will also be processed by your
+EVT\_MENU event handlers.

+Note that menu commands (and UI update events for menus) are first sent to
+the focus window within the frame. If no window within the frame has the focus,
+then the events are sent directly to the frame. This allows command and UI update
+handling to be processed by specific windows and controls, and not necessarily
+by the application frame.
