Table header font shape is different between Windows OS and Raspberry Pi

[SGaist]

Hi,

You should add:

• Qt version
• Linux distributions
• Desktop environment

Both on your desktop and RPi.

@SGaist

Qt version: 5.15.2
Linux distributions: Ubuntu 20.04.3 LTS
Desktop environment: window10

I doubt there is the same data - in one screenshot you've 'WaveLength', in the other 'WaveLength5' - maybe there are linebreaks too. Make sure that you work on the same data when comparing screenshots.

@Christian-Ehrlicher

I have already confirmed that I have the same data.
Putting 5 on it was just to make sure the text changes.

[Christian Ehrlicher]

Use a simple model (or QTableWidget) without your test application to see if it's really a program on the Qt side (which I doubt).
Also try to start with a different style (e.g. windows) on your raspberry.

I also did several tests. I tested it after running it on Ubuntu OS, but I think it is a problem on the qt side
Because when I ran the same in Ubuntu environment, the result was the same with Raspberry. And there are several people who are raising this issue.

[Christian Ehrlicher]

So did you actually run it on the raspberry pi with the windows style?

[IknowQT]

@Christian-Ehrlicher

Are you referring to the desktop version of the Windows-style Raspberry Pi?
I'm developing in a raspberry environment on the desktop version.

[Christian Ehrlicher]

I don't understand your question.
You posted a screenshot with a wrong height. Start this application with the windows style and see if it's still an issue.

@IknowQT first check what styles are available on your target OS

qDebug() << QStyleFactory::keys();

than set it to "Windows" if available

QApplication app(argc, argv);
qDebug() << QStyleFactory::keys();
app.setStyle(QStyleFactory::create("Windows"));
