[Qt-interest] QTabBar bold font in tab text

[franki]

Hi,

The problem is:
Customer panel is derived from QTabWidget and has some tabs with some widget's 
in which operator (person) can edit data. When data is changed in any widget 
I check it, and i set bold font in QLabel that is "buddy" for this widget. 
I'm doing this by setting: QFont fontBold; fontBold.setBold(true); 
widget->setFont(fontBold)
So far so good. 
Next I wanted to have tabs in which there is modified and unsaved data to be 
also marked with bold font. Even when user switches to other tab, and he 
leaves unsaved data this tab should remain marked with bold font until he  
comes back and save the data.
That's the problem.
If I set setFont for widget, or QTabBar - all text, or all tabs are marked 
bold.
In my class that is derived from QTabWidget I have:

QTabBar *tabBar() const { return QTabWidget::tabBar(); }

So I can access the tabBar and for example use setTabTextColor - to mark this 
tab with different color - that's some kind of solution, but other "buddy" 
labels are marked with bold font, so tabText should be bold to.

If I use setStyleSheet I can make bold font, but there is also a problem:

this->tabBar()->setStyleSheet("QTabBar::tab { font:bold }");

This sets all tabs with bold text, if I use Pseudo-States like activ, 
selected, etc. - it changes when user switch to other tab, and I need to keep 
this tab bold until data is saved.

I could use setProperty and then make styleSheet for widget with particular 
property, but the real problem is, that I can't, or don't know how to access 
one tab in QTabBar (for example by knowing it's index number)
I have seen, that in QT3 there was QTab* QTabBar::tab(int) which gives access 
to particular tab, but this is no longer available.
I read 
http://qt.nokia.com/doc/4.5/stylesheet-examples.html 
and 
http://qt.nokia.com/doc/4.5/stylesheet-reference.html 
and I didn't find solution.
How to access particular tab in QTabBar (by its index number) or how to set 
font:bold with styleSheet for particular tab which preserve bold font when 
user switches to other tabs?

Thanks in advance.
