PySide.QtGui.QGraphicsSceneMoveEvent class provides events for widget moving in the graphics view framework.
A PySide.QtGui.QGraphicsWidget sends itself a PySide.QtGui.QGraphicsSceneMoveEvent immediately when its local position changes. The delivery is implemented as part of QGraphicsItem.itemChange() .
It's similar to PySide.QtGui.QMoveEvent , but its positions, PySide.QtGui.QGraphicsSceneMoveEvent.oldPos() and PySide.QtGui.QGraphicsSceneMoveEvent.newPos() ，使用 PySide.QtCore.QPointF 而不是 PySide.QtCore.QPoint .
