When calling move() on a QWinWidget before it is shown then it will not be placed correctly

When calling move() on a QWinWidget before it is shown then it will not be placed correctly. This is not a problem in the solution itself but in the QWidget code for Windows.

This is a regresion against Qt 4.4.3.

To reproduce, add the line win.move(50,50) to before the win.show() line in the winwidget example in the Qt/MFC Migration solution.
