[SOLVED]QGraphicsScenes move

lwx_me

Hi,
I have two QGraphicsViews with two QGraphicsScenes up down,and they zoom in same size with the same attributes.
[Turn on QGraphicsView::ScrollHandDrag ,disables scrolls with Qt::ScrollBarAlwaysOff,Qt::ScrollBarAlwaysOff]

The question is how can I drag to move one scene and the other moveing toghter.

Thanks

You can use signals and slots to talk between the two views. The scroll bars still trigger their valueChanged signal even if they are not visible.

I would also take a look at the chip demo.

@
connect(graphicsView1->horizontalScrollBar(),SIGNAL(valueChanged(int)),graphicsView2,SLOT(sliderValueChanged(int)));

connect(graphicsView2->horizontalScrollBar(),SIGNAL(valueChanged(int)),graphicsView1,SLOT(sliderValueChanged(int)));
