def run(self):
        global EXIT  # 定义全局变量，这个可以在不同线程间共用。

        if not user32.RegisterHotKey(None, id2, 0, win32con.VK_F10):   # 注册快捷键F10并判断是否成功，该热键用于结束程序，且最好这么结束，否则影响下一次注册热键。
            print("Unable to register id", id2)

        # 以下为检测热键是否被按下，并在最后释放快捷键
        try:
            msg = ctypes.wintypes.MSG()
            while True:
                if user32.GetMessageA(ctypes.byref(msg), None, 0, 0) != 0:
                    if msg.message == win32con.WM_HOTKEY:
                        if msg.wParam == id2:
                            EXIT=True
                            return
                    user32.TranslateMessage(ctypes.byref(msg))
                    user32.DispatchMessageA(ctypes.byref(msg))
        finally:
            user32.UnregisterHotKey(None, id2)# 必须得释放热键，否则下次就会注册失败，所以当程序异常退出，没有释放热键，
                                              # 那么下次很可能就没办法注册成功了，这时可以换一个热键测试
