PyQt fails on MacOS (Apple silicon)

daryllee

I finally decided to give PyQt a chance to replace Tkinter today, but it's not going well. I'm on a MacBook Air with M2 chip, MacOS 14.4.1, Python 3.12. I did "pip install pyqt5" and "pip install pyqt5-tools"and then tried the program below. It ran with no error messages but did not produce a window. So I upgraded to PyQt6, but the pip install pyqt-toolsgot stuck on these few lines of output:

Collecting pyqt6-tools
  Downloading pyqt6_tools-6.1.0.3.2-py3-none-any.whl.metadata (8.3 kB)
Collecting pyqt6==6.1.0 (from pyqt6-tools)

Ctl-C did no good. I had to open another terminal session totry my program and got the same result: no errors, no window. Any suggestions?

My starter program.

from PyQt5 import QtWidgets
from PyQt5.QtWidgets import QApplication, QMainWindow
import sys

def window():
    xpos = 200
    ypos = 200
    width = 300
    height = 300

    app = QApplication(sys.argv)
    win = QMainWindow()
    win.setGeometry(xpos, ypos, width, height)
    win.setWindowTitle("Tech with Tim")


    # Contents


    win.show()
    sys.exit(app.exit())

if __name__ == "__main__":
    window()

Hi

It's app.exec() that you should use. Your call to app.exit() stops the application before it can start.
