Menu Item

  • 项目

A menu item represents a particular item in a menu bar or pop-up menu. For example, Active Accessibility creates a menu item object for the File menu in the menu bar. Similarly, Active Accessibility creates a menu item object for the Open menu item from the File pop-up menu.

The window class name for a menu item is "#32768".

Remarks

When used on a menu item, accDoDefaultAction returns S_OK but fails to perform the action if the character used in the access key is ?, !, @, or any other character that requires the SHIFT key or another modifier key. This also happens on international keyboards with an access key character that requires the ALT GR key to be pressed.

The accSelect method with SELFLAG_TAKEFOCUS does not cause a menu item to open or close a pop-up menu. Clients use the accDoDefaultAction method to open or close a pop-up menu.

A menu bar item that does not display a pop-up menu returns "Application" for the Name property instead of the name of the menu item.
