Thanks, Richard. That would work perfectly, but my UI is mostly <span style="color:rgb(121,93,163); font-family:Consolas,'Liberation Mono',Courier,monospace; font-size:14px; white-space:pre; widows:auto; background-color:rgb(255,255,255)">QTreeWidgetItem</span> 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? <br>

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