QTabBar styling

Hi folks!
I'd like to style each page button on QTabBar identified by custom property (or index).
Is it even possible? The problem is that custom (page) property is associated with pane, not tab bar.
I'm looking for something like

Code:

---

QTabBar::tab[currentIndex=0] { background: yellow; }

---

But this doesn't work. What I found in documentation is identifying first, last, selected and hoved.

Use different stylesheet for each tab bar.

Thanks for your answer ... but I don't understand how to do it. I have a simple hierarchy QDialog->QTabWidget->[QWidget, QWidget]
Could you possibly provide me some short example? Thanks
