importing class

[gmarkowsky at gmail.com]

Thanks, I got that part. The problem I'm still having is that it's not
seeing things like text_1, which are defined in the program. How can I
make it see that?

Another question I should ask is whether I should even bother doing
this. That is, it seems that the elegant and approved way of doing this
kind of thing may be to put a class in a module and then just use the
module over and over again in programs. I'm making a few GUIs which
present two options and ask the user to chose one, so I thought I could
just do it this way. Of course I could very easily just copy and paste
the class into each file, but that seems silly. I haven't had any
trouble using modules for functions, but for classes it is not working
right so far, and I'm having trouble finding examples to follow.
