A thread updating GUI in PySide6

[AlexP11223]

I need to listen for messages from other processes and do something with GUI when a message is received, e.g. creating a new window.

So I use multiprocessing.connection for the first part, but of course I need a separate thread to unblock the UI thread.

What is the right way to do it in PySide6? I guess I need a QThread, but I am not sure how to use it here.

import multiprocessing.connection
import sys
from PySide6.QtWidgets import QApplication

if __name__ == '__main__':
    # do this in a separate thread 
    listener = multiprocessing.connection.Listener(('localhost', 6000), 'AF_INET')
    while True:
        client = listener.accept()
        s = client.recv()
        client.close()
        widget = MyWindow()
        widget.set_content(s) 
        widget.show()

    # UI thread 
    app = QApplication([])

    sys.exit(app.exec())

It's much simpler to use Qt's asynchronous nature e.g. QTcpServer. No need for threads, multiprocessing or blocking.
