//  PopupMenu sub-class of QPopupMenu created by Tim.

//=========================================================
//
// NOTICE: This sub-class of QPopupMenu *automatically* deletes
//          and *clears* any sub popup menus, when clear() is called.
//         Therefore a parent widget is *not* necessary when 
//          creating sub popup menus to add to the popup.
