WIDGET_BASE

The following keywords to the WIDGET_BASE function are obsolete.

Keywords

APP_MBAR

Set this keyword to a named variable that defines a widget application's menubar. On the Macintosh, the menubar defined by APP_MBAR becomes the system menubar (the menubar at the top of the Macintosh screen). On Motif platforms and under Microsoft Windows, the APP_MBAR is treated in exactly the same fashion as the menubar created with the MBAR keyword. See "MBAR" on page 2115 for details on creating menubars.


Warning
You cannot specify both an APP_MBAR and an MBAR for the same top-level base widget. Doing so will cause an error.

To apply actions triggered by menu items to widgets other than the base that includes the menubar, use the KBRD_FOCUS_EVENTS keyword to keep track of which widget has (or last had) the keyboard focus.
