[PyQt] restoreState not working for QDockWidgets

[Phil Thompson]

This is not a self contained example, ie. one that we can run. How do you
know that these are the "relevant pieces"? By presenting us with a fragment
of code you are making the assumption that it must demonstrate the problem
- even though you have already said you don't know what the problem is.

One possible problem is that you are not giving the dock widget a name (see
the docs for QMainWindow.saveState()), but as your fragment has "# snip"
below the call to create it then who can tell?
