<description><p>A menu bar is a series of menus accessible from the top of a frame.
      </p><p>Remark: To respond to a menu selection, provide a handler for EVT_MENU, in the frame that contains the menu bar.
      </p><p> If you have a toolbar which uses the same identifiers as your EVT_MENU entries, events from the toolbar will also be processed by your EVT_MENU event handlers.
      </p><p>Tip: under Windows, if you discover that menu shortcuts (for example, Alt-F to show the file menu) are not working, check any EVT_CHAR events you are handling in child windows. If you are not calling event.Skip() for events that you don't process in these event handlers, menu shortcuts may cease to work.
