Custom Speedometer Widget

I just started using style sheets for my objects in Qt to change colors / geometry / etc. I would like to try to make a Custom Speedometer, or even just a meter. I am getting streaming data from a Tcp socket and would like to use the speedometer or circular meter to show a visual representation of the streaming values coming in the socket. My thought would be to do a QStyleSheet on a QDial.

Does anyone know of a good example to look at?

Thanks!
