wx.MenuEvent¶This class is used for a variety of menu-related events.
Note that these do not include menu command events, which are handled using wx.CommandEvent objects.
Events of this class are generated by both menus that are part of a wx.MenuBar, attached to wx.Frame, and popup menus shown by wx.Window.PopupMenu . They are sent to the following objects until one of them handles the event:
The menu object itself, as returned by GetMenu, if any.
The wx.MenuBar to which this menu is attached, if any.
The window associated with the menu, e.g. the one calling PopupMenu() for the popup menus.
The top level parent of that window if it’s different from the window itself.
This is similar to command events generated by the menu items, but, unlike them, wx.MenuEvent are only sent to the window itself and its top level parent but not any intermediate windows in the hierarchy.
The default handler for wxEVT_MENU_HIGHLIGHT in wx.Frame displays help text in the status bar, see wx.Frame.SetStatusBarPane .
^^
Events Emitted by this Class¶Handlers bound for the following event types will receive a wx.MenuEvent parameter.
EVT_MENU_OPEN: A menu is about to be opened. On Windows, this is only sent once for each navigation of the menubar (up until all menus have closed).
EVT_MENU_CLOSE: A menu has been just closed. Notice that this event is currently being sent before the menu selection ( wxEVT_MENU ) event, if any.
EVT_MENU_HIGHLIGHT: The menu item with the specified id has been highlighted: used to show help prompts in the status bar by wx.Frame
EVT_MENU_HIGHLIGHT_ALL: A menu item has been highlighted, i.e. the currently selected menu item has changed. ^^
