[PyQt] Range slider?

[Hazen Babcock]

Hello,

Does anyone know if a widget like this:
http://www.codeproject.com/KB/miscctrl/CRangeSlider/CRangeSlider.gif
exists for Qt? This being the slider in the upper left corner of the  
image which lets the user define a range or interval.

If not, any suggestions on how to go about creating one?

I'm currently using to two sliders that are coupled to each other,  
one to set the high value and the other to set the low value, but I  
think this would be a lot cooler...

thanks,
