Move graphicsView

[jano_alex_es]

Hi,

I have a QGraphicsScene, and when it needs the scroll bars when I click on the scene I move the graphicsView around it (QGraphicsView::ScrollHandDrag).

I suppose this is the desired behavour... but which event controls it? which event is launched when the user "moves" the view? I've tried with a lot of them (all the drag events in scene and view, for examle, are not called), in both graphicsScene and graphicsView and I don't find it :S

thanks!

It's probably mouseMoveEvent() in QGraphicsView.

Thanks! didn't think on that.

By the way, in order to learn a bit more, there is no event launched when the user clicks on the scene and moves it around?

The user can't "move the scene around". Scene is your world, there is no "around" it, you can only change its dimensions.

I just said that because that's the effect it does; the well made definition is "scroll the scroll bars".

Scrollbars move your view onto the scene. Exactly the same way ScrollHandDrag does.
