Additional Information
- After detecting a valid mouse click (when the mouse is pointing to a control area on a window), a process needs to call SS.MnSel. This calls tells the enhanced window interface to handle any menu selection being made. If accumulator A returns with 0, then no selection has been made. The calling process needs to test and handle other returned values.
- A condition where Register A returns a valid menu ID number and Register B returns 0 signals the selection of a menu with no items. The application can now take over and do a special graphics pull down of its own. The menu title remains highlighted until the application calls the SS.UMBar SetStat to update the menu bar.
- The support module for this call is WindInt.
