Qt fontsize don't take in account font size from Qt Designer

[mihdim777]

Hello!

I am trying to modify an application for amateur radio, to fit into a raspberry pi screen 7" (800x480). And the original application minimum resolution is 1024x780.

I have a main form designed with Qt Designer and I'd like to lower the fonts. All good in designer but when I compile the application it does not take in account the font that I chose. Also not working if I choose a very big font.

I am compiling on Ubuntu/Raspbian and no success on both.

How should I force the resolution from Qt Designer to be in executable application?

I also tried to change with Tweaks the font of Ubuntu, but the qt app doesn't change.

Thank you!

Hi and welcome to devnet,

Can you provide a minimal compilable examples that shows this behaviour ?

Hello! Yes sure!
The software is called WSJTX. It can be found on github.

I would like to know if there are any method to force the qt font from qt designer?
This is the font that I would like:

Check Generate Std Msgs button for example, it should have smaller font:

But instead I get this when I compile the code:

@SGaist So do you think this is os font problem or it can be from qt? maybe overwrite somewhere?

check your ui_*** files to see the font settings.
