public class QGraphicsSceneWheelEvent
The QGraphicsSceneWheelEvent
class provides wheel events in the graphics view framework.The QGraphicsSceneWheelEvent
class provides wheel events in the graphics view framework. QWheelEvent
s received by a QGraphicsView
are translated into QGraphicsSceneWheelEvents; it translates the QWheelEvent::globalPos()
into item, scene, and screen coordinates (pos()
, scenePos()
, and screenPos()
).
