The scene - then forwards the events to the relevant items. - - For example, when a QGraphicsView receives a QMouseEvent of type - MousePress as a response to a user click, the view sends a - QGraphicsSceneMouseEvent of type GraphicsSceneMousePress to the - underlying QGraphicsScene through its - \l{QGraphicsScene::}{mousePressEvent()} function.
