Try calling .setObjectName() in the constructor of your dock widget
subclass. That's required for the standard QGIS dock arrangement
save/restore code to work correctly. (That's all that's needed -- you
don't need to manually do any calls to saveGeometry/restoreGeometry).

Also I suggest using the QgsDockWidget subclass as the base class for
your widget, as it has some extra niceness added on top of the
standard Qt QDockWidget class.

However, the dimensions of the widget is not saved and I am not able to figure out how to restore the width and height of the widget. I tried to use QDockWidget::restoreGeometry without success. Could someone please point me how to achieve this? Thanks!
