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?
