Process finished with exit code -1073741819 (0xC0000005)

在主界面初始化时调用：Qthread

  thread = Mythread()

  thread.start()

结果报错了

Qthread不能是临时变量，因为线程需要持续执行，临时变量会马上销毁，

解决方法：

self.thread = Mythread()

self.thread.start()

Mythread代码：

class Mythread(QThread):
    # 定义信号,定义参数为str类型
    def __init__(self, parent=None):
        super().__init__(parent)
        #  super(Mythread, self).__init__()
    def callb_error(self, err_type, cam_no, msg_no, msg_level, msg_txt, msg_txtlen):
        print(“myerror”, err_type, cam_no, msg_no, msg_level, msg_txt, msg_txtlen)
    def run(self):
        file_name=”d:/201805070000.dat”
        self.filename = bytes(file_name, encoding=”utf8″)
        begin = datetime.datetime.now()
        print(1111)
