PyQt5 QThread.self.setTerminationEnabled(False)似乎不起作用

借款自 PySide QThread.terminate() causing fatal python error 我试过这个例子:

from PyQt5 import QtCore, QtGui, QtWidgets


class Looper(QtCore.QThread):
    """QThread that prints natural numbers, one by one to stdout."""
    def __init__(self, *args, **kwargs):
        super(Looper, self).__init__(*args, **kwargs)
        # self.setTerminationEnabled(True)
        
        self.setTerminationEnabled(False)

    def run(self):
        i = 0
        while True:
            self.msleep(100)
            print(i)
            i += 1

# Initialize and start a looper.                                                                      
looper = Looper()

looper.setTerminationEnabled(False)
looper.start()

# Sleep main thread for 5 seconds.                                                                    
QtCore.QThread.sleep(3)

# Terminate looper.                                                                                   
looper.terminate()

app = QtWidgets.QApplication([])
app.exec_()

我可能错了,但意料之中 looper.setTerminationEnabled(False) 或 self.setTerminationEnabled(False) 以防止QThread terminate() 根据 https://doc.qt.io/qtforpython-6/PySide6/QtCore/QThread.html#PySide6.QtCore.PySide6.QtCore.QThread.setTerminationEnabled 。

但对我来说,这行不通。有什么提示吗??

我正在使用 Qt: v 5.15.2 PyQt: v 5.15.7
