Programatically make a tab's text bold

[Vadi2]

How can I programatically make a tab's text bold?

I'm looking to notify the user that they need to look at it.

Hi
Perhaps you could use a stylesheet and change the current tab to highlight it
QTabBar::tab:selected. { font-weight: bold; }

[Vadi2]

I need to specifically choose which tab to make bold, and it can't be just the currently selected - it could be unselected too. Any ideas?

@Vadi2
since its random tabs, not sure you can target that with stylesheet.
I was wondering if text color could work, so instead of Bold, then some color ?

A colour is different because the user could have a custom theme that conflicts. I'd really like it bold - like Firefox can and so on.

can the tabText be HTML? this would allow any kind of formatting, including bold.

I tried setTabText(i, "<b>testing</b>"); and it did not work.

mmh, haven't tried it, but I think, you can potentially set an Icon, that spans the whole tab width, that would give the illusion a modified Tab-Text ?

Edit:

Google search, brought me to this old forum post

@SGaist and @Goutye
had the right idea, re-implement paintEvent seems to be agood (the best?) option

Hi,
I supposed that you have a QTabWidget and just wants to change the style of one tab button. Have you tried something like:

myTabWigdet->tabBar()->tabButton(myIndex, 0)->setStyleSheet("MyStyle");

[Vadi2]

The tab button (X) is not what I'm looking for - I want to grab the tab itself, not the close button within it :(

Using re-implemented paintEvent() is too complicated. Rather, i think using something like QProxyStyle would be a better choice.

[J.Hilk]

@Devopia53 when I read my Interest-Email feed correctly, than the OP has a solution to the problem, with indeed using QProxyStyle. But hasn't updated the topic to solved yet.

since when is re-implemented paintEvent() to complicated? Thats about 20 lines of code to get the desired result, in this case at least.

Yep, solved with http://lists.qt-project.org/pipermail/interest/2018-April/029734.html. Thanks everyone.
