ABSTRACT:
A computer system and method of operation are disclosed that simplifies the menu bar for use by a group of active applications. The computer system typically uses a bus coupled to a central processing unit and further coupled via the bus to a computer system memory. The computer system further includes an X Window menu manager and an X Window menu bar, both of which are located within the computer system memory during operation. The X Window menu manager includes a shared menu library. The X Window menu manager implements simultaneously instantiation of a set of menu widgets from the shared menu library that are associated with a computer program selected from the several active computer programs when the program focus is shifted to one of the active programs. The X Window menu bar, which is controlled by the X Window menu manager and displayable by the computer system, is shared by the plurality of active programs so that only the computer program receiving the application focus has its associated set of menu widgets displayed after the focus shift. The method for providing the shared menu bar is accomplished as follows. Initially, the system establishes a part editor for each active application. Next, the system passes the focus to one of the active applications and then retrieves a copy of a base menu bar from a window state object in the X Window environment. Afterwards, the system selects the appropriate widgets for display on the computer system. Next, the base menu bar is displayed and then the part editor is notified of the selected widgets to be displayed in the shared menu bar. Lastly, the system displays the selected widgets in the base menu bar or X Window menu bar.
