[Qt-interest] Get style of a subcontrol

[Peter Radagast]

For example I have set following CSS:
 QTabBar::tab
 {
    font-family: "Arial";
    color: #323232;
 }

is it possible to get this font as a QFont in the source code? QTabBar::font() returns another one, and I don't see any way to get access to a subcontrol.
Thanks in advance.
