问题描述
我已经安排了很长的进程在线程中运行,因为否则它将冻结我的wxpython应用程序中的ui.
I have a long process that i've scheduled to run in a thread, because otherwise it will freeze the ui in my wxpython application.
我正在使用
threading.Thread(target = myLongProcess).start()
启动线程,它可以工作,但是我不知道如何暂停和恢复线程.我在python文档中查找了上述方法,但找不到它们.
to start the thread and it works, but I don't know how to pause and resume the thread. I looked in the python docs for the above methods, but wasn't able to find them.
有人可以建议我怎么做吗?
Could anyone suggest how I could do this?
谢谢.
推荐答案
我自己遇到了同样的问题,直到找到答案为止.
I was having the same issue myself, until I found the answer.
我也进行了一些速度测试,在速度较慢的2处理器Linux机器上,设置标志和采取措施的时间非常快,为0.00002秒.
I did some speed tests as well, the time to set the flag and for action to be taken is pleasantly fast 0.00002 secs on a slow 2 processor Linux box.

import threading
import time
# This function gets called by our thread.. so it basically becomes the thread innit..
def wait_for_event(e):
while True:
print '\tTHREAD: This is the thread speaking, we are Waiting for event to start..'
event_is_set = e.wait()
print '\tTHREAD: WHOOOOOO HOOOO WE GOT A SIGNAL : %s', event_is_set
e.clear()
# Main code..
e = threading.Event()
t = threading.Thread(name='your_mum',
target=wait_for_event,
args=(e,))
t.start()
while True:
print 'MAIN LOOP: still in the main loop..'
time.sleep(4)
print 'MAIN LOOP: I just set the flag..'
e.set()
print 'MAIN LOOP: now Im gonna do some processing n shi-t'
time.sleep(4)
print 'MAIN LOOP: .. some more procesing im doing yeahhhh'
time.sleep(4)
print 'MAIN LOOP: ok ready, soon we will repeat the loop..'
time.sleep(2)
