How can both graphicsView and graphicsItem receive mousemoveEvent?

[christina123y]

Have you seen QGraphicsView::dragMode ?

I have looked up QGraphicsView::dragMode in the QT assitant.But i don't know how this can help me? I have written eventfilter in the QGraphicsItem class,but it does nothing. There still only mouse move position tracking,but can't draw a rubberband rect,not less than zoom in through select a rubberband rect
