I have a widget with 4 QGraphicsViews and I want them to be dockable. I've put a QGraphicsView in a QDockWidget. Then I was able to undock the view, but I don't know how to dock the view back, where it was. At the begin, there is a bar with an undock button, but when the widget is undocked, then this bar is gone.
What do I need to do, to dock the widget on it's original/starting position? Or is this QDockWidget not for things like that? I would be very grateful for some help.
