I am not aware of such a list but maybe findChildren would be a more
elegant solution (just found this one:
http://www.qtcentre.org/threads/22812-How-to-get-list-of-DockWidgets-in-QMainWindow).

setFloating only makes the dock widget a floating one which then always
stays on top of the main window and is not treated as an individual
window (with title bar, task bar entry, alt-tab etc.). The Qt::Window
flag is needed for that.

I remember restoreState and restoreGemoetry of the main window did not
restore the correct sizes and (floating)-state of the dock widget in
every situation (fullscreen etc.). Thats why the loop over all dock
widget is necessary.
