QDockWidget drag/drop preview

Hi all,

Maybe I'm missing some important step, but I'd like to disable the preview of final docked position when drag/dropping a QDockWidget.
If I'm not wrong, I have to setAnimated(false) at QMainWindow.

But it seems not working. Do I need anything else?

Thanks a lot.

Well, my fault.
I've just noticed the difference between animation enabled/disabled. I thought setting animation off would avoid painting the target location.
I should implement my own DragMoveEvent handler, shouldn't I?
