I think that the problem is that Qt4 does not allow this kind of (x,y) positionning of the toolbars. Qt4 just needs to know the logical position (top, bottom, left, or right) of the toolbars and the order.
I am not quite sure. As I have said, if you stop at show(), with an added move() call, the toolbars will be moved, just that they are moved back by something else. Bo
