Calling winId() into my promoted QWidget's constructor (and not just in there), causes a lot weird problems in a QMainWindow.

      Calling winId() on my promoted widget to get the native window handle causes serious weird problems with DockWidgets and, in my real application, it even bugs the order of Show/Hide events. The problem is not just with the Qt::Tool style not being applied.

      Also, we've a flood with these:
      QBackingStore::flush() called with non-exposed window, behavior is undefined

      I really need the handle, to integrate Ogre in there.

      I've attached a Qt project that shows the issue.
