Unsolved can I change default fontsize?
-
Hi,
I'm using Qt6.2 (binary edition) on debian 11.
The window with the black titlebar is my app created with Qt. Afaik kde is built with Qt too, so I expect the default styles follow KDE-styles in use.
But thats not the case:
Red boxes 1 and 2 show default font of kde windows.
Green boxes 3 and 4 show default gnome fonts on kde. Ok, I admit, that gnome is not well supported in kde systems ...
But imho Qt should follow kde rules ...Even more strange is blue box 5 - that's an editor build following the sample qt code from editor with line numbers. I changed the font of QPlainTextEdit (the source view). That changed font is not respected by the QPainter build on every call of paintLineNumbers.
I had to add a line like:
painter.setFont(font());
to get the line numbers of same size as displayed code.
I had to increase the font sizes by 4 points to get same visual impression than compiled with Qt5.15 ...
Is there a way to change default fontsize once (at application startup or so)?

Hi
Yes
you can set on ApplicationQApplication a(argc, argv); a.setFont(QFont("Arial",25));
But you cant have stylesheets that set fonts also as then it wont override.

Hi,
thank you very much for the hint! Works great!
The elements where I manually change font continue to work as before.
... and the elements, I don't want to use bother with font size use the new application font. Great!Thanks again - that's exactly what I was looking for :)
