Thanks for the quick reply. With your reply and another tutorial I get
it now. I needed "self.Rows = ..." in the constructor. I find myself
wasting a lot of time with poor python docs. Whatever time Python is
supposed to save I'm losing so far in looking up things. I suppose that
will change as I get past the learning curve. Are you aware of any good
docs on python that make it easy to find things?
