Thanks, Richard. That would work perfectly, but my UI is mostly QTreeWidgetItem
elements. Apparently, those don't emit valueChanged signals, so I can't use
your code (unless I've got that wrong). I therefore either have to find some
other signal I can hook into, or save the settings at some other point. Any
ideas?

Not sure if it is the best way, but actually whenever the user changes
something (by clicking or inputting something) you can 'save' it to
settings.
As an example:
https://github.com/rduivenvoorde/featuregridcreator/blob/master/FeatureGridCreator/grid_creator.py#L173
I create two helper functions to set and get settings value (and make it
possible to return a default value in case setting is not set).
and all the getter setter's are used when the user clicks (changes)
something in the dialog. So the settings are being constantly in sync
with the user latest choices...
But there are probably other ways too :-)

Richard Duivenvoorde
