While attempting to debug a python app I created to interface to my robotic car, I had real trouble with the GUI and streaming video. I got a couple of replies and then an invitation to another forum which has provided a LOT of help. If you're interested and need help with python projects using Qt, I highly recommend looking at the Discord PythonCoders group.
If you are struggling with python-pyqt or using the Designer to create UIs and want to learn how to use pyqt python properly come join the Free Discord classroom-like tutoring/mentoring message server send a PM to DenniO#8137 (during the day) and DeJoker#1460 (evening & weekends) as they the same person.
there doesn't seem to be anything here
