NSMenu canelTracking is not working on Mac OSx 10.5

I m using NSComboBox inside NSMenu to show a list of items. When I choose any option in NSComboBox menu should get dismissed.

To dismiss NSMenu I m using cancelTrackingWithoutAnimation for 10.6 and above and it works fine. In case of 10.5 i am using cancelTracking but it is not dismissing NSMenu.

Solution

  • I fixed the issue by using carbon API CancelMenuTracking(), 

    CancelMenuTracking(
  MenuRef   inRootMenu,
  Boolean   inImmediate,
  UInt32    inDismissalReason)

    Used _NSGetCarbonMenu to get the menuref of NSMenu.

    menuRef = _NSGetCarbonMenu(myMenu);

    CancelMenuTracking(menuRef,YES,kHIMenuDismissedByCancelMenuTracking); for 10.5 and CancelMenuTracking(menuRef,YES,0); for 10.6 and above
