Thanks so much for this information and the example. It is going to take
me quite some time figure out all this stuff. I'm pretty new to this
side of programming in general. I'm sure I'll have more questions, so
I'll send another email when I can.

Pretty much, this application has no need for really different widgets,
just a different face and shape on those widgets. All I would really
want to do is change things such as the depth and background color of a
text field, or make a button with two images instead of the usual
looking button, or something similiar to that. Or overridethe usual
shape on a tab panel, and make it a shape and color I wanted. Is this
what I would do? I'm still confused.
