这一节记录的是我在使用python tkinter时的一些笔记。
背景：现在需要构建一个简易的聊天工具，说简易是因为确实只需要很简单的几个界面，包括一个登陆界面、一个好友列表和单击好友时弹出好友对话框可以交谈，我们这里只需要创建简单的界面（不包括业务），所以选择用tkinter这个模块来实现。
要点一、神马是tkinter？
Tkinter模块("Tk 接口")是Python的标准Tk GUI工具包的接口.Tk和Tkinter可以在大多数的Unix平台下使用,同样可以应用在Windows和Macintosh系统里.,Tk8.0的后续版本可以实现本地窗口风格,并良好地运行在绝大多数平台中.（摘自百度百科）想要查看你的Tkinter版本，只需要在python命令行模式下输入print Tkinter.TkVersion即可，笔者的版本是8.5。
要点二、安装
一般情况下，安装python时，自带安装了Tkinter，并且与python的版本相对应，例如python2.7.3对应的应该是8.5版本，其余的我倒不是很熟悉。但有些预安装的python可能没有带上tkinter，例如我在虚拟机Fedora17上的python并没有自带tkinter，这时候解决办法是使用yum install tkinter命令即可。
要点三、登陆框
View Code
1 # -*- coding: utf-8 -*-
2 import Tkinter
3 from Tkinter import *
4 from multiprocessing import Process,Pipe
5 class Login:
6 def __init__(self,master,con):
7 self.con = con#pipe connection
8 self.parent = master#Tk实例，父容器
9 self.username = ""
10 self.password=""
11 master.protocol("WM_DELETE_WINDOW", self.cancel)#绑定关闭按钮到cancel函数
12 self.__layout__(master)
13
14 pass
15
16 #布局
17 def __layout__(self,master):
18 master.geometry("320x150+400+100")#窗口大小及坐标
19 master.title("腾Q登陆框")
20
21 row1 = Frame(master)
22 row1.pack(padx=10,pady=15)
23 Label(row1,width=8,text="用户名：",anchor=W).pack(side=LEFT)
24 self.en_user = Entry(row1)
25 self.en_user.pack(side=LEFT)
26
27 row2 = Frame(master)
28 row2.pack(padx=10,pady=0)
29 Label(row2,width=8,text="密码：",anchor=W).pack(side=LEFT)
30 self.en_pswd = Entry(row2,show="*")
31 self.en_pswd.pack(side=LEFT)
32
33 row3 = Frame(master)
34 row3.pack(padx=10,pady=15)
35 Button(row3,text="确定",width=10,command=self.ok).pack(side=LEFT,padx=5)
36 Button(row3,text="取消",width=10,command=self.cancel).pack(side=LEFT,padx=5)
37 pass
38
39 def ok(self):
40 self.username = self.en_user.get()
41 self.password = self.en_pswd.get()
42 if not self.validate():
43 print "usrname or password error"
44 return
45 self.con.send({"res":True,"data":(self.username,self.password)})
46 self.parent.quit()
47 self.parent.destroy()
48 pass
49
50 #验证账号密码
51 def validate(self):
52 return True
53
54 def cancel(self):
55 self.con.send({"res":False,"data":(self.username,self.password)})
56 self.parent.quit()
57 self.parent.destroy()
58 pass 效果如图：
要点四、好友列表

13
14 #在这里导入个人资料，至少包含name属性
15 def __loadmyself__(self):
16 self.me = {"name":u"沉鱼落雁"}
17 pass
18
19 def __layout__(self,master):
20 master.geometry("320x720+400+0")
21 master.title("腾Q")
22
23 f_message = Frame(master)
24 f_message.pack(fill=X)
25
26 Label(f_message,text=self.me['name']+"(online)").grid(row=0,sticky=W,pady=10,padx=5)
27 Label(f_message,text="好友列表：").grid(row=1,sticky=W)
28
29
30 f_friendlist = Frame(master)
31 f_friendlist.pack(fill=BOTH)
32 #带滚动条
33 scrollbar = Scrollbar(f_friendlist, orient=VERTICAL)
34
35 self.listbox = Listbox(f_friendlist,yscrollcommand=scrollbar.set,height=700)
36 scrollbar.config(command=self.listbox.yview)
37 scrollbar.pack(side=RIGHT, fill=Y)
38 self.listbox.bind("<Double-Button-1>",self.show)
39 self.refreshfriends()
40 self.listbox.pack(fill=BOTH,expand=1)
41 pass
42
43 #在这里导入好友列表
44 def loadfriends(self):
45 #reading friends list from server
46 #for example:(needs to be modified)
47 self.friendlist = [{"ID":0,"name":u"xxx","state":"on"},{"ID":1,"name":u"范德萨","state":"off"}]
48
49 fl = self.friendlist
50 for obj in fl:
51 self.listbox.insert(END,"%s(%s)"% (obj["name"],obj["state"]))
52 for i in range(2,50):
53 obj = {"ID":i,"name":u"王老吉%d"%i,"state":"on"}
54 self.friendlist.append(obj)
55 self.listbox.insert(END,"%s(%s)"% (obj["name"],obj["state"]))
56 pass
57
58 #更新好友列表，通常是周期性更新好友状态
59 def refreshfriends(self):
60 self.listbox.delete(0,END)
61 self.loadfriends()
62 pass
63
64 #开启对话框
65 def show(self,event):
66 lb = self.listbox;
67 ss = lb.curselection()
68 if len(ss) == 1:
69 #print lb.curselection(),lb.get(lb.curselection())
70 index = string.atoi(ss[0])
71 if index >= len(self.friendlist) :
72 print "error",index,len(self.friendlist)
73 else:
74 obj = self.friendlist[index]
75 if not obj.has_key("open"):
76 self.__openchat__(obj)
77 else:
78 if not obj["open"] == "yes":
79 self.__openchat__(obj)
80 else:
81 print obj['ID']," alreay open"
82 #print self.friendlist[ss[0]]
