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. | |
