I'm trying to figure out a few things with the plasmoid I'm developing in Python, and I need good example code. I've downloaded several python plasmoids from kde-look, but I'm not seeing examples of the things I need to understand.

Can someone recommend to me an example of a Python Plasmoid that is a great piece of code to emulate? Specifically, I'd like to examine one that:
- has a configuration dialog loaded from a .ui file
- uses KConfig XT
- talks to a dataengine
- For bonus points, queries a server and provides configuration options based on the answer it gets.
