如何知道 QThread 是正确退出还是被终止？

Question

我发现在 Qt 4.8 中有终止信号，您可以在此处看到： http://doc.qt.io/archives/qt-4.8/qthread.html#terminated

但是现在Qt 5.8中没有这样的东西了。 http://doc.qt.io/archives/qt-5.8/qthread.html

如果线程完成，即使线程终止，似乎也会发出完成信号。但是是否有选项可以知道 QThread 是正确退出还是被终止？

我使用了@Scheff 提出的以下模式

class MyQThread(QThread):
    def __init__(self):
        self.__terminated = None
        super().__init__()

    def wasTerminated(self):
        if self.__terminated is None:
            return True
        return False

    def run(self):
        # Add at end of run
        self.__terminated = False

并在来电中跟随：

class Worker(QObject):
    def __init__(self):
        super().__init__()
        self.thread = MyQThread()
        self.thread.finished.connect(self.finishedSlot)

    def finishedSlot(self):
        if self.thread.wasTerminated():
            print("Thread was killed before finished")
        else:
            print("Thread results are ok")

如何知道 QThread 是正确退出还是被终止？
