I should not overload that method. You should provide your own
implementation of HandleEvent
http://root.cern.ch/root/htmldoc/TGWindow.html#TGWindow:HandleEvent 

http://root.cern.ch/root/htmldoc/Event_t.html


in case EGEventType Event_t.fType = kMapNotify | kUnmapNotify,
(see: http://root.cern.ch/root/htmldoc/GuiTypes.h )

bool YourCustomWidget::HandleEvent(Event_t *event){

  switch (event->fType) {
    case kMapNotify:   your map action;   break; 
    case kUnmapNotify: your unmap action; break;
  };
  return YourCustomWidgetBaseClass::HandleEvent(event);
}
