[commonqt-devel] Zoom in/out QGraphicsView centering on mouse position

[Rujia Liu]

Hi!

I want to implement a AutoCAD-like zoom in/out behavior and found this:

http://www.qtcentre.org/threads/35738-How-to-zooming-like-in-AutoCAD-with-QGraphicsView

I tried to use scale+centerOn (also in wheel event) but it doesn't work. It
is scaled properly but does NOT center on the given point. Is there any
workaround?
