Can we restrict the movement of a Qt Window?

[Frank J. Lhota]

What about moving the window back to its previous position?
Read this: http://doc.trolltech.com/4.4/qwidget.html#pos-prop (and read the Warning carefully).

I found a way to do this using a Qt event filter. This event filter does not actually filter any events. It does, however, looks at the move events and moves any window back to its initial location. Thanks.
