I'm sorry I didn't respond before now, I've been swamped at work.

I agree that this would be a useful addition to matplotlib. I had been 
thinking myself about whether to invest some time to develop some standard 
widgets. This is a good place to start, I'll commit a modified version 
sometime in the next week (it should respect rcParams, for example), but I'll 
need some instructions on how to make Designer use the plugin. Would you 
please consider writing a brief instruction that could be included in the 
backend_qt4agg source?

Thanks for the submission,
Darren
