title: Adding extra operations to the mouseReleaseEvent
body: <p>For QGraphicsItem (I have a class subclass of this QGraphicsItem), there is in-built mouseReleaseEvent method and that is private. As of now, this is used in making the Graphic Item to pan and to update the position(Built in feature). I want to add additional features, like printing the position where it is released and some other statements. How should I achieve this?</p>
