MDIMenu Property
Applies To: MenuBar
Description
This property specifies the name of, or ref to, the Menu object that is nominated as the "Window" menu in an MDI application. If such a menu is defined, the Captions of all the child Forms are automatically added to it below any other Menu or MenuItem objects that the application has created directly. This list is separated from the preceding items by a separator. The entry for the currently active SubForm is checked and the user may switch between SubForms by selecting from this list.
Note that the additional separator and the items representing the list of child forms are not Dyalog APL/W objects and may not be accessed by the application. If you prefer to maintain your own "window list" you should not use this property.
