I have added my derived DockableGroupPane object to the DockArea. When I double click the Group Area tab, its dock state changed to floating. When I double click the float window title, it is not set back to its original dock area. Instead it sites in top location.
Hello,
I tried this and it always works fine for me and since I do not have your derived 'DockableGroupPane' I attached my sample to this post for you. Please review it and feel free to let me know if I misunderstood you or if you have any other questions.
