How to get the "real" position of the QGraphicsView/QGraphicsScene ?
I have a QGraphicsScene which is very large(eg. (5000, 5000)), how to get the real logic postion of it?
I tried globalPos, localPos, pos, screenPos, windowPos...it's all not what i want.
or should I condider the panned center pos after I panned the scene?
The "Graphics View Coordinate System":http://qt-project.org/doc/qt-5/graphicsview.html#the-graphics-view-coordinate-system article should be helpful.
