I work with views and delegates instead of the corresponding 'widget'
widgets. In my case I use the delegate feature of the views for my
combo boxes. I think they feed back into the regular path of setting
data via the view. Does that not apply to QTableWidget? Do you really
have to have a callback or will it set the value back into the table
If not, I do in various places use lambdas, functions, and
functools.partial to attach identifier sorts of information in the path
p = functools.partial(the_slot, from=the_relevant_object)
And add `from` as a parameter on `the_slot`.
