Help for beginner in Python project (Pyside6 with QThread)

[SakuOrdrTab]

Greetings all, I did some tutorials with Python and to learn more I started this larger learning project..

I am trying to do a application where balls randomly collide on screen with eachother. I thought Pyside6 was the best bet to learn GUIs and chose that. However, as I had to put ball physics and screen refreshing on a different thread, things became somewhat difficult and now I have multiple issues that I find difficult to get progress on.

If you happen to have time to check out my project, the code is in
https://github.com/SakuOrdrTab/bouncing_balls

I have the issues in the according github tab, too and there is a discussion tab. I am sorry to say, I am not very fluent in GitHub either, so there might be some problems posting there, hope not though.

I appreciate any help with the issues, but general recommandations are useful, too. I am wondering if I have divided the project in sensible modules and is y general approach totally awkward. Also, if this is not the right place to ask for project help, is there a more appropriate site, perhaps?

Well, after a year of crashing my head to the wall, I finally got it to work.

Sorry if this was the wrong place for this kind of requests, but for any future beginners tampering with Pyside/PyQT, please regard:
I had a main thread taking care of the GUI and then another thread taking care of balls moving, colliding and doing their things in their window. I was unfortunate enough for manipulating the GUI from the other thread (drawing the balls in new positions) and this messes up the program real bad.
It seems that if you need to alter the GUI from another thread, connect it with the main thread with a signal and do the alteration there.

Happy coding, everyone!
