QDetachTabWidget is an extenstion of QTabWidget to implement detachable tabs.
Doing a RMB click on any tab in the tab widget will bring up a small menu to detach the tab into a separate window. The separated window can be resized and moved anywhere on your screen. Note, it can not be closed using the window's menu bar.
In the QDetachTabWidget, a blank widget is put in the place of the detached widget. This blank widget will have a 'Reattach' button in its center. QDetachTabWidget remembers the detached widget and the placeholder widget. If you RMB click on the tab again, it will show the small menu again where you can then reattach the widget.
This implemenation handles the cases of movable tabs and closeable tabs.
