Ahh.. you use a stylesheet in addition to this, and it's not applying.. It's likely something in your code here that is preventing the stylesheet from having effect.
Take a look at one of the other styles like Plastique and see how they do things with their Progress Bar delegate.
It will be in the C++ sources of Qt. (Sorry, it's not implemented in Python - but it should be reasonably understandable even to someone coming from Python, if they're familiar with the Qt API).
Let me see if I can dig it up.
Oh man I'm dating myself.. They moved the Plastique style out of Qt a long while back I think in the transition from 4.8 to 5.0.
What I think you want to look at is the Fusion style, which is defined here:
https://github.com/qt/qtbase/blob/dev/src/widgets/styles/qfusionstyle.cpp
You'll want to look at drawPrimitive and drawComplexControl.
Actually, this will have you diving into how the call to drawControl you make works, which should show what is happening.
I typically do this with stylesheets:
