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.
