Closing pyqt5 GUI without killing the launching Python script

Question

I'm having an issue with a Python script that launches a pyqt5 GUI. Once the GUI is started from the launching script, the user has to provide some inputs and then close the application through a Close button. The method associated with the button ends with a "sys.exit()" to close the GUI.

The problem is that this command closes both the GUI and the launching Python script.

Is there a way to close just the GUI and not the launching script (that in my case has to do other stuff).

Answer 1

Change the method to not call sys.exit() , which terminates the process, but rather qApp.exit() , which only exits the qApp event loop (exec()) which you call in main ?

Othewrise, sys.exit() raises SystemExit exception, so maybe you can catch in main or by overriding QApplication.notify .
