 268 A demo of using wx.MenuBar and wx.Menu in various ways.
 269
 270 A menu is a popup (or pull down) list of items, one of which may be selected
 271 before the menu goes away (clicking elsewhere dismisses the menu). Menus may be
 272 used to construct either menu bars or popup menus.
 273
 274 A menu item has an integer ID associated with it which can be used to identify
 275 the selection, or to change the menu item in some way. A menu item with a special
 276 identifier -1 is a separator item and doesn't have an associated command but just
 277 makes a separator line appear in the menu.
 278
 279 Menu items may be either normal items, check items or radio items. Normal items
 280 don't have any special properties while the check items have a boolean flag associated
 281 to them and they show a checkmark in the menu when the flag is set. wxWindows
 282 automatically toggles the flag value when the item is clicked and its value may
 283 be retrieved using either IsChecked method of wx.Menu or wx.MenuBar itself or by
 284 using wxEvent.IsChecked when you get the menu notification for the item in question.
 285
 286 The radio items are similar to the check items except that all the other items
 287 in the same radio group are unchecked when a radio item is checked. The radio group
 288 is formed by a contiguous range of radio items, i.e. it starts at the first item of
 289 this kind and ends with the first item of a different kind (or the end of the menu).
 290 Notice that because the radio groups are defined in terms of the item positions
 291 inserting or removing the items in the menu containing the radio items risks to not
 292 work correctly. Finally note that the radio items are only supported under Windows
 293 and GTK+ currently.
