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-QG... 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? - Rujia
