Menu Bar (MSAA UI Element Reference)

Note  This topic describes Menu Bar objects for purposes of MSAA UI Element Reference. How to create Menu Bar objects in various UI frameworks is not described here. See the API reference documentation for the UI framework you're using.

A menu bar is the area of a window immediately beneath the title bar that contains menu items such as File, Edit, Window, and Help. Microsoft Active Accessibility also creates a menu bar object for a system menu, which is the menu in the top left corner of the title bar and contains menu items such as Restore, Move, Size, Minimize, and Maximize.

Note  Because menu bar controls do not receive focus, the accSelect and get_accFocus methods are not supported for this control.

IAccessible Methods

Menu bar controls support the following IAccessible methods:

IAccessible Properties

Menu bar controls support the following IAccessible properties:

PropertyComments

Notes

The system triggers more than one EVENT_SYSTEM_MENUSTART event that does not always have a corresponding EVENT_SYSTEM_MENUEND event. Additionally, the system does not trigger the EVENT_SYSTEM_MENUPOPUPSTART and EVENT_SYSTEM_MENUPOPUPEND events consistently. This is a known issue and is being addressed.
