Hi everybody,

hope someone can help me. I have a widget with a QGraphicsView, QTableView, QListView and a QTreeView. Each of them should be un/dockable. The undocking works, but how can I dock them back to the starting position? I don't want to drag them, I want to press a button and dock them back. Like how I undock them. At the beginning there is a bar with this undock-button. But after the undocking, this bar is gone.
I don't know what I need to do, to dock them back (with a button-press). Here is a bit code. I would be very thankful, if someone could help me out.

Kind regards,
Xinor
