python - 有没有办法在 Tkinter 中暂停和恢复线程？

Question

我通常使用以下命令启动线程，threading.Thread(target=function_name).start()有什么办法可以暂停它threading.Thread(target=name).wait()简历就像threading.Thread(target=name).set()

检查如何this项目。该项目满足您的所有要求。 Python 的内置线程模块目前不支持播放和暂停功能。
所以要安装这些模块:pip install pythreadworker安装后这里是一个例子:

from worker import Worker  # We import the Worker to create thread

def some_long_running_task(foo, bar, tee="foo"):
    do_random_long_stuff()
    # ...

if __name__ == '__main__':
    # to make a thread we initialise Worker or somewhat so called the Thread of threading module
    thread = Worker(some_long_running_task)  # remember just pass the function without execution parenthesis

    # Now to start thread while also supplying arguments, we call start method
    thread.start("bar", bar="foo", tee=123)

    # To pause a the thread we use pause method
    thread.pause()

    # To resume it we use resume method
    thread.resume()

    # To use the Thread.join Worker class, use the join method
    thread.join()

    # And to kill it we use 
    thread.stop()

但是，如果您使用 time.sleep，请记住使用它。
那么你将不得不用 worker.sleep 替换它
所以例如你导入代码是

from time import sleep

将其替换为

from worker import sleep

希望这可以帮助。
