QgraphicsView QgraphicsScene size policy

[arsinte_andrei]

I have a strange behavior that I do not know how to manage it. I wish to have some more background around the objects that I already have on the scene in the view how can I archive this without scaling down this is not what I expect. Reason behind this is that if the user wish to work on the corner of the graphics to have enough space to move the objects around - I saw that it will be automatically enlarged if I will move the object more to the corner and then I will bring it back but I wish to do this programmatically . so basic another at least 20px around the edge objects and yes if the user will get closer again to the edge again by itself to enlarge the size.
