You must subclass it since virtual void grabMouseEvent ( QEvent * event ) (in fact all mouse events) is(are) protected and there are no signals for click events for this widget.

class MyGraphicsWidget : public QGraphicsWidget{

Q_OBJECT

//Implement the constructors as you wish, if you need help with this check a Qt tutorial out.

  //to get the mouse events implement the needed functions
  //there are many others so just check the docs [1]
  virtual void mouseReleaseEvent ( QGraphicsSceneMouseEvent * event ){
    //do whatever you need here. Emit SIGNALS, show menus, etc
  }
};
