Question

Python

Hello everyone, I wrote a code in Python, pyqt5, but for some reason it looks different on different devices. I care about the style of the buttons, etc.
How the code looks for me

And like the rest

, Windows is the same, the code is the same, the python is the same
Maybe I don’t have some kind of checkmark in Windows

Answer 1

As far as I understand, if you do not set your own styles, system ones are used, which may differ for different versions of Windows assemblies. write css styles for the elements, should fix the position

Answer 2

Did you collect the executable?
If yes, then read about manifest here
