tree widget like designer's widget tree

[nroberts]

I'd like a toolbox thing sort of like the widget tree in the designer. As far as I can tell, for the categories it simply adds a top level tree item to a basic QTreeWidget subclass. I can't recreate the way the categories draw themselves in the designer though. How is this done?

It's done by sheet_delegate.

Thanks for all the help.
