Hi Marcus,
Thanks for your feedback. I decided to create a separate class for the
widget that are used in the tab widget, and when that widget is deleted run
a function to cleanup the model. Not sure if this is the "proper" way to do
it. I have not yet tried the pymotw to inspect the gc, will look into that.
BR,
Johan
