How to handle multithreaded programming in PyQt5?
In PyQt5, handling multithreaded programming can be done using either Python’s built-in threading module or the QThread class.
Utilizing the threading module.
import threading
def worker():
print("Worker thread")
thread = threading.Thread(target=worker)
thread.start()
Using the QThread class:
from PyQt5.QtCore import QThread
class Worker(QThread):
def run(self):
print("Worker thread")
worker = Worker()
worker.start()
Regardless of the method used, it is important to avoid executing time-consuming operations in the main thread to prevent blocking the GUI interface. You can communicate between the main thread and sub-threads using the signal-slot mechanism, or handle operations after a thread has finished executing using QThread’s finished signal.
