Tkinter Canvas 如何绑定ScrollBar

murdercool

代码如下，
Canvas 绑定ScrollBar  但是只能点击 滚动条上的上下键滚动，滑块没作用，哪位大哥帮忙看下原因，谢谢
！！
ps：Listbox是成功的

1. import Tkinter
   
2. root = Tkinter.Tk()
   
3. class a:
   
4.     def __init__(self,master):
   
5.    
   
6.         self.master=master
   
7.         self.frame=Tkinter.Frame(self.master)
   
8.         self.frame.pack()
   
9.         
   
10.         self.chatTextScrollBar = Tkinter.Scrollbar(self.frame)
    
11.         self.chatTextScrollBar.pack(side=Tkinter.RIGHT, fill=Tkinter.Y)
    
12.         
    
13.         self.mylist = Tkinter.Canvas(self.frame)
    
14.         self.add_image=Tkinter.PhotoImage(file='add.gif')
    
15.         for line in range(20):
    
16.             self.mylist.create_image((30,20+line*50),image =self.add_image)
    
17.         self.mylist.pack( side = Tkinter.LEFT, fill = Tkinter.BOTH )
    
18.         self.chatTextScrollBar["command"]=self.mylist.yview
    
19.         #self.mylist["yscrollcommand"]=self.chatTextScrollBar.set
    
20. a=a(root)
    
21. root.mainloop()

如果要滚动，则要配置cancas的参数scrollregion为你合适的滚动大小 (w, n, e, s)。

楼主，我在做canvas与scrollbar的时候也出现了问题，想请教你一下，他们两个已经绑定了，但是滚动条无法控制绑定内容。代码如下，麻烦高手帮我看看
