Make sure you set a minimum size that's larger than what fits in the panel on 
the widget() or graphicsWidget() (e.g. setMinimumSize(320, 240)). That's what 
I had done wrong first in my Ruby plasmoid and it just never worked. I think 
it's been added to the documentation now, but I'm not sure.
Apart from that I don't think that I can help that much. I'm not really into 
Python after all.
