Quick and dirty:

struct Style : QProxyStyle
{
void drawControl(ControlElement element, const QStyleOption *opt, QPainter 
*p, const QWidget *w) const
{
if (element == QStyle::CE_TabBarTab) {
QFont f = p->font();
f.setBold(true);
p->setFont(f);
}
QProxyStyle::drawControl(element, opt, p, w);
}
};

...
yourTabWidget()->tabBar()->>setStyle(new Style);


May need some polish.

Using widgets? You didn't say what context.

Maybe you can set a dynamic property on the tab when you want it to be
bold, and attach a special style using properties in the stylesheet.

Yes, using widgets.

I've tried a dynamic property however as far as I can see, I can only 
set the dynamic property on the entire tab bar - not a specific tab. 
How can I set it on a specific tab?

[René Hansen]

Alternatively suffix an asterisk; Tab -> Tab*. Then remove it on highlight.

Note that this is different from using a stylesheet to set the 
selected tab bold - I'd like to set any random tab's text bold.


Been looking at this for several days, appreciate any advice!
