+ \class QGraphicsSceneEvent
+ \brief The QGraphicsSceneEvent class provides a base class for all
+ graphics view related events.
+ \since 4.2
+ \ingroup multimedia
+ \ingroup graphicsview-api
+
+ When a QGraphicsView receives Qt mouse, keyboard, and drag and
+ drop events (QMouseEvent, QKeyEvent, QDragEvent, etc.), it
+ translates them into instances of QGraphicsSceneEvent subclasses
+ and forwards them to the QGraphicsScene it displays. 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. The default
+ QGraphicsScene::mousePressEvent() implementation determines which
+ item was clicked and forwards the event to
+ QGraphicsItem::mousePressEvent().
+
+ \omit ### Beskrive widget() \endomit
+
+ Subclasses such as QGraphicsSceneMouseEvent and
+ QGraphicsSceneContextMenuEvent provide the coordinates from the
+ original QEvent in screen, scene, and item coordinates (see
+ \l{QGraphicsSceneMouseEvent::}{screenPos()},
+ \l{QGraphicsSceneMouseEvent::}{scenePos()}, and
+ \l{QGraphicsSceneMouseEvent::}{pos()}). The item coordinates are
+ set by the QGraphicsScene before it forwards the event to the
+ event to a QGraphicsItem. The mouse events also add the
+ possibility to retrieve the coordinates from the last event
+ received by the view (see
+ \l{QGraphicsSceneMouseEvent::}{lastScreenPos()},
+ \l{QGraphicsSceneMouseEvent::}{lastScenePos()}, and
+ \l{QGraphicsSceneMouseEvent::}{lastPos()}).
