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