这篇博客通过一个示例展示了如何在Python中结合多线程和GTK库来控制线程的暂停和继续。主要使用了threading模块的Event对象，通过设置和清除Event的状态来控制线程的执行。GTK界面包含开始、停止按钮，实现对遍历文件夹操作的线程控制。

import threading

import os

event = threading.Event()

def walk(path):
event.wait()
try:
if os.path.isdir(path):
for file in os.listdir(path):
file_path = os.path.join(path, file)
for sub_file in walk(file_path):
yield sub_file
else:
yield path
except:
print "read file error!!"

def func():
for file in walk("/"):
print file

def test():
th2 = threading.Thread(target=func)
th2.setDaemon(True)
