python的tkinter布局之简单的聊天窗口实现方法

from Tkinter import *
import datetime
import time
root = Tk()
root.title(unicode('与xxx聊天中','eucgb2312_cn'))
#发送按钮事件
def sendmessage():
  #在聊天内容上方加一行 显示发送人及发送时间
  msgcontent = unicode('我:','eucgb2312_cn') + time.strftime("%Y-%m-%d %H:%M:%S",time.localtime()) + '\n '
  text_msglist.insert(END, msgcontent, 'green')
  text_msglist.insert(END, text_msg.get('0.0', END))
  text_msg.delete('0.0', END)

#创建几个frame作为容器
frame_left_top   = Frame(width=380, height=270, bg='white')
frame_left_center  = Frame(width=380, height=100, bg='white')
frame_left_bottom  = Frame(width=380, height=20)
frame_right     = Frame(width=170, height=400, bg='white')
##创建需要的几个元素
text_msglist    = Text(frame_left_top)
text_msg      = Text(frame_left_center);
button_sendmsg   = Button(frame_left_bottom, text=unicode('发送','eucgb2312_cn'), command=sendmessage)
#创建一个绿色的tag
text_msglist.tag_config('green', foreground='#008B00')
#使用grid设置各个容器位置
frame_left_top.grid(row=0, column=0, padx=2, pady=5)
frame_left_center.grid(row=1, column=0, padx=2, pady=5)
frame_left_bottom.grid(row=2, column=0)
frame_right.grid(row=0, column=1, rowspan=3, padx=4, pady=5)
frame_left_top.grid_propagate(0)
frame_left_center.grid_propagate(0)
frame_left_bottom.grid_propagate(0)
#把元素填充进frame
text_msglist.grid()
text_msg.grid()
button_sendmsg.grid(sticky=E)
#主事件循环
root.mainloop()
