Frame overrides handleEvent()

This technique is often used in the Sun examples/tests

class MyFrame extends Frame {
   public boolean handleEvent(Event evt)
   {
      switch (evt.id) {
         case Event.ACTION_EVENT: {
            if ("Quit".equals(evt.arg)) {
               // handle Quit button ...
               return true;
             } else // ...
         }
         // case ...
      }
      return super.handleEvent(evt);
   }
}
