pyqt5 QThread关闭子线程，停止正在执行的函数例子

很好，这是一个技术问题。以下是一个例子，可以用于关闭子线程并停止正在执行的函数：

import sys
import time
from PyQt5.QtCore import QThread, pyqtSignal, QObject

class Worker(QObject):
    finished = pyqtSignal()
    progress = pyqtSignal(int)

    def __init__(self, parent=None):
        super(Worker, self).__init__(parent)

    def run(self):
        count = 0
        while True:
            time.sleep(1)
            count += 1
            self.progress.emit(count)
            if count == 10:
                break
        self.finished.emit()

class ExampleThread(QThread):
    def __init__(self, parent=None):
        super(ExampleThread, self).__init__(parent)
        self.worker = Worker()

    def run(self):
        self.worker.run()

    def stop(self):
        self.worker.terminate()

class Example():
    def __init__(self):
        self.thread = ExampleThread()
        self.thread.finished.connect(self.on_finished)
        self.thread.progress.connect(self.on_progress)
        self.thread.start()

    def on_finished(self):
        print('Thread finished')

    def on_progress(self, count):
        print('Count:', count)

    def stop_thread(self):
        self.thread.stop()

if __name__ == '__main__':
    app = QApplication(sys.argv)
    example = Example()
    time.sleep(3)
    example.stop_thread()
    sys.exit(app.exec_())

希望这个例子能够帮到你。
