NAME

wxMenuEvent - Functions for wxMenuEvent class

DESCRIPTION

This class is used for a variety of menu-related events. Note that these do not include menu command events, which are handled using wxCommandEvent objects.

Events of this class are generated by both menus that are part of a wxMenuBar, attached to wxFrame, and popup menus shown by wxWindow:popupMenu/4. 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 wxMenuBar 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, wxMenuEvent 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 wxFrame displays help text in the status bar, see wxFrame:setStatusBarPane/2.

See: wxCommandEvent, Overview events

This class is derived (and can use functions) from: wxEvent

DATA TYPES

wxMenuEvent() = wx:wx_object()

wxMenu() = 
    #wxMenu{type = wxMenuEvent:wxMenuEventType(),
            menuId = integer(),
            menu = wxMenu:wxMenu()}

wxMenuEventType() = menu_open | menu_close | menu_highlight

Types:

This = wxMenuEvent()

This method should be only used with the HIGHLIGHT events.
