python Tkinter的Text组件中创建x轴和y轴滚动条，并且text文本框自动更新（三）

要求对文件边读边写并显示对话框。

1.加线程之后，必须要文件写完才显示对话框。错误代码：

 1 # encoding: utf-8
 2 import time
 3 from Tkinter import *
 4 import threading

 7 def write(file1,file2):
 8     with open(file1, 'r+') as f1:
 9         for line in f1:
10             # print line
11             f2 = open(file2, 'a+')
12             f2.write(line)
13             time.sleep(0.00001)

15 
16 def windows1(file2):
17     root = Tk()
18     root.title("serial log")
19     s1 = Scrollbar(root)
20     s1.pack(side=RIGHT, fill=Y)
21     s2 = Scrollbar(root, orient=HORIZONTAL)
22     s2.pack(side=BOTTOM, fill=X)
23     textpad = Text(root, yscrollcommand=s1.set, xscrollcommand=s2.set, wrap='none')
24     textpad.pack(expand=YES, fill=BOTH)
25     s1.config(command=textpad.yview)
26     s2.config(command=textpad.xview)
27     with open(file2) as f:
28         while True:
29             line = f.readline()
30             textpad.pack()
31             textpad.insert(END, line)
32             textpad.see(END)
33             root.update()
34 if __name__ == '__main__':
35     file1 = 'log.txt'
36     file2 = 'result.txt'
37     threads = []
38     t1 = threading.Thread(target=write,args=(file1,file2))
39     threads.append(t1)
40     t2 = threading.Thread(target=windows1,args=(file2,))
41     threads.append(t2)
42     for t in threads:
43         # t.setDaemon(True)
44         t.start()
45     # for t in threads:
46     #     t.join()

注：# t.setDaemon(True)禁掉是因为写文件只运行了一行。# t.join() 因为程序会卡死。错误原因start()使用需要重新写run()。

正确代码：

调用两个类

以上代码在python2.7.9上运行可行。
