In the attachement small example that shows the problem. By default
QGraphicsItem must be movable by mouse but he doesn't...
Hi.
I've implemented QGraphicsItem and want to receive mouseReleaseEvent.
I've reimplemented mouseReleaseEvent virtual method but he doesn't
invoked.
Why?
I've checked this method with QGraphicsScene and there he works but
not in QGraphicsItem.
Why again?
