QPointF QGraphicsSceneHoverEvent:: lastScenePos () const

Returns the last recorded, the scene coordinates of the previous mouse or hover event received by the view, that created the event mouse cursor position in scene coordinates.

該函數在 Qt 4.4 引入。

另請參閱 lastPos (), lastScreenPos ()，和 scenePos ().

QPoint QGraphicsSceneHoverEvent:: lastScreenPos () const

Returns the last recorded mouse cursor position in screen coordinates. The last recorded position is the position of the previous mouse or hover event received by the view that created the event.

該函數在 Qt 4.4 引入。

另請參閱 lastPos (), lastScenePos ()，和 screenPos ().
