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

    Description

      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.
