Detailed Description

When a QGraphicsView receives a QMouseEvent , it translates it to a QGraphicsSceneMouseEvent . The event is then forwarded to the QGraphicsScene associated with the view. If the event is not handled by the scene, the view may use it, e.g., for the DragMode .

In addition to containing the item, scene, and screen coordinates of the event (as pos() , scenePos() , and screenPos() ), mouse events also contain the coordinates of the previous mouse event received by the view. These can be retrieved with lastPos() , lastScreenPos() , and lastScenePos() .
