c++ - Hide label text for Qt tabs without setting text to empty string

Question

I need a QTabWidget with icons only:

How can I hide the label text of a tab in Qt? I cannot set the text to an empty string (""), as I am using docked widgets ( QDockWidget ) and the label text is set automatically (and I need it if the widget is floating).

But in tabbed mode I just want to display the icons (of the tabs). Possible approaches:

1. Font size to 0?
2. I need to create my own bar class and override the paint event as here

Anything easier / cleaner?

--- Edit ---

Ok, the "set window title to empty string, and reset it the original text" approach works. I am using the topLevelChanged signal for this. However, it has some drawbacks, as the empty text still occupies some space. Another issue, with the text the tooltip is gone, and I cannot set it back.

What I am currently trying is something in-between the "text empty" and Prasad Silva's approach. I try to identify the text label inside the tab and set its size to 0, then reset it. It's slightly different, but would keep the text intact.

Btw, I see a line on top of my tabs, any idea what this is (where it comes from)? Edit: There seems to be no "easy way" (style sheet, attribute) for this, see Hiding bottom line in QTabBar

Maybe I will create the whole tab bar on my own, as the automatically generated stuff is just too hard to handle (agree with PS on this).

This can not be done easily. Use empty text.
