A wx:menu% object is a pop-up or pull-down list of items, one of which may be selected before the menu goes away. Menus can be used to construct either menu bars or popup menus.
Each menu item has an associated integer identifier. This identifier is used when an item is selected by the user (see also on-menu-command). It can also be used to change the menu item in some way.
A menu can be used in only one menu bar or as a pop-up menu.
If the title argument is not null, it may be used when the menu is used as a pop-up menu. If func is not null, it will be called when the user selects an item by a call to popup-menu or popup-menu.
