The problem with doing it that way is that you can't connect the signals
using designer, and have to do it by hand in you code. Which is kinda
stone-agey ;-)

Sure, you can define the signals and slots in Designer, but then it
doesn't really generate the right code (I mentioned that in my tutorial

I think the main thing needed to be able to use custom python widgets in
designer "the right way" would be a way to create a widget plugin.

Check Qt designer's manual, chapter 7 "Creating Custom Widgets with
Plugins" to see what I mean.

The bad news is that I am not sure how that could be done for python
widgets. The good news are there's a lot of smart people on this list ;-)
