[PySide] inherited values that contribute to widgets position

As you are asking about animation, I am assuming you are
using QtGui.QGraphicsView.

Working with QGraphicsView, I found following few key things related to

1. By default QtGui.QGraphicsView aligns the scene to center. So all
resizes are set wrt center. To change the anchoring back to top, use


2. If you are trying to get resizable scene, you may want to
use resizeEvent of QtGui.QGraphicsView and adjust your widgets/layouts.

3. Have a default screen size so that widget reference starting point is
something you can always control. You could also do relative distances
based on the screen size - but it is some more initialization that you need
to take care of.

Hope above is what you are looking for.
