Hello -

I have a similar question:

In my case I would like a specific column of the table to be a set of exclusive
choices given by a set of radio buttons.

Oh, is this functionality available in QTableWidget?  I could manage with
QTableWidget instead of QTableView.  I've looked at the documentation
for QTableWidget and QTableWidgetItem, and I don't see how to put a
widget of my choice -- for example, "radio-button-valued" cell -- in my table.

I don't need my own model.  So if QTableWidget supports putting a custom
widget in a cell, could someone please point me to some documentation
or an example that could get me started?

In my case I have made some progress.  I am using a QItemDelegate
(following the Spin Box Delegate Example in the qt documentation)
to use a set of radio buttons to *edit* my item.  But I would also like
to use radio buttons to *display* the item.

I see that QItemDelegate has a paint() method, but I don't see how I
would use it (short of painting an image of the radio buttons from scratch.)

I want to be able to use a custom widget -- ideally as automatically as
possible -- for both display and editing of the data in the table.

(Note, for me this is not an urgent question.  I am trying to learn and
understand qt.  I would like to explore the kinds of things qt has been
designed and built to do, and learn the "best-practices," qt way of doing
things.)

Thanks for any advice and insight.
