Python3 - Pyqt5如何通过异常或按下退出按钮来结束线程中的循环

import threading

# 定义一个继承自Thread的自定义线程类
class MyThread(threading.Thread):
    def __init__(self):
        threading.Thread.__init__(self)
        self.is_running = True

    def run(self):
        while self.is_running:
            try:
                # 线程循环的代码
                pass
            except Exception as e:
                # 捕获异常并终止线程循环
                self.is_running = False
                print("线程异常终止:", e)

# 创建并启动线程
thread = MyThread()
thread.start()

# 在需要的时候，通过抛出异常来终止线程循环
try:
    # 其他代码
    pass
except Exception as e:
    # 抛出异常终止线程循环
    thread.is_running = False
    raise e

import threading
from PyQt5.QtWidgets import QApplication, QMainWindow, QPushButton

# 定义一个继承自Thread的自定义线程类
class MyThread(threading.Thread):
    def __init__(self):
        threading.Thread.__init__(self)
        self.is_running = True

    def run(self):
        while self.is_running:
            # 线程循环的代码
            pass

# 创建并启动线程
thread = MyThread()
thread.start()

# 创建一个PyQt5应用程序
app = QApplication([])
window = QMainWindow()
window.setGeometry(100, 100, 200, 100)

# 创建一个按钮，并绑定点击事件
button = QPushButton("退出", window)
button.setGeometry(50, 30, 100, 30)
button.clicked.connect(lambda: thread.is_running = False)  # 点击按钮时终止线程循环

# 显示窗口
window.show()
app.exec_()
