How can I dock a QDockWidget back to it's starting position

[xinor]

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

To copy to clipboard, switch view to plain text mode

Hi,

I had the same problem; a default 'undock' button to detach the dock, but once it is undocked there is only a close button. I don't know if it is possible to get a 're-dock' button in a dock, I use something like this to restore my docks to their original position:

dock->setFloating(False)

dock->setFloating(False)

To copy to clipboard, switch view to plain text mode

Hahaha thank you so much julietbravo! I don't know if that is the best way to do it, but it is working

Hi guys,

one more problem. When a widget is undocked/floating and I'm moving the mainwindow, then the floating widget is moving too.
The widgets are also separate by QSplitter and if I'm dragging a splitter, then the floating widgets are resized too.
How can I disable this behavior for the floating/undocked widgets? Is there any way?

Kind regards,
Xinor

Hi all,

Not sure what version of Qt you were using when you posted this thread, anyway there is a way easier solution to make dockwidgets go back to their original location in Qt 4.8 and later versions :
Simply double click the title bar of the floating dockwidget.

Simply double click the title bar of the floating dockwidget.

Well, that's great, but I think the original poster wanted a way to do it with code not the mouse...
