App still running in background after closing the app

[07rohanraj]

I have created an .exe using PyInstaller, but when I close the application, it continues running in the background, and I have to end the task from the Task Manager.
I tried recieving signal for the close window event and was planning to close all the threads running but couldn't get any signal (tried with SIGTERM) for that.

signal.sigaction(signal.SIGTERM, signal.SIG_IGN, handle_shutdown)

Hi @07rohanraj,

It looks like this is a duplicate of #2107 and/or #3931. Can you confirm that?

Hi @falkoschindler
Yes, both are same issue.

Ok, so let's focus on #2107. 👍

Actually, my issue has been resolved. This is working for me now:

def shutdown_app():
    print("Shutting down the application...")
    logging.info("Shutting down the application...")
    sys.exit(0)
 
# app.on_startup(startup_app)
app.on_shutdown(shutdown_app)

ui.run(native=True, window_size=(1400, 800), reload=False, port=native.find_open_port())
