我有这个课程,这是我的话题。通过创建该类的实例,我创建了我的线程,因此通过调用其stop方法,它应该被终止或终止,但不是。不知道为什么如果有人可以帮助我,我将不胜感激。
Class MyThread(threading.Thread):
# Thread class with a _stop() method.
# The thread itself has to check
# regularly for the stopped() condition.
def __init__(self, last_time=0, start_time=0, label="", root="", speed_mode=""):
super(MyThread, self).__init__()
self.label = label
self.last_time = last_time
self.start_time = start_time
self.root = root
self.speed_mode = speed_mode
self._stop_event = threading.Event()
# function using _stop function
def start_counter(self):
self.start_time += 1
self.label['text'] = self.start_time
# self.start_time = start_time
if self.start_time < self.last_time:
self.label.after(DIC_TIME[self.speed_mode], self.start_counter)
def stop(self):
self._stop_event.set()
def stopped(self):
return self._stop_event.isSet()
def run(self):
self.start_counter()
while True:
if self.stopped():
return
我希望通过调用MyThread类的stop方法,使tinter canvas中的标签重新启动并停止运行(label是第二个计数器)
