[SOLVED] How To Style Tab Background on Mac OSX

[maximo]

Anyone know how, on Mac OSX, I can style the QTabWidget (or sub controls in it) so that I can change the dark grey background color shown in this image, as well as the dark border at the top of it?

The solution is an undocumented trick:

QTabBar 
{
background-color: transparent;
qproperty-drawBase:0;
}

This lets you make the dark grey area (called the "tab bar base") as transparent. Or, alternatively, you can style it by changing the background-color value to a color.
