Когда я нажимаю кнопку qbtn, чтобы выйти из GUI, GUI исчезает, но процесс в convert(filename) продолжает выполняться в фоновом режиме.
Как сделать так, чтобы при пользователь нажимает кнопку выхода, GUI исчезает и любой запущенный процесс завершается?
Я использую pyqt5 GUI (ниже):

try:
# PyInstaller creates a temp folder and stores path in _MEIPASS
base_path = Path(sys._MEIPASS).joinpath('files').absolute()
except Exception:
base_path = Path(".").absolute()
logo_path = base_path.joinpath('pi_logo.png')
return str(logo_path.absolute())
