Tkinter AttributeError：對象沒有屬性'tk'

Question

我查了一下，但找不到我錯誤的答案。下面是代碼：

import tkinter as tk 

root=tk.Tk() 

class Page(tk.Frame): 
    '''Enables switching between pages of a window.''' 
    def __init__(self): 
     self.widgets={} 
     self.grid(column=0,row=0) 

page=Page() 

tk.mainloop() 

以下是錯誤：

Traceback (most recent call last): 
    File "C:\Documents and Settings\Desktop\Python Scripts\Tkinter.py", line 11, in <module> 
    page=Page() 
    File "C:\Documents and Settings\Desktop\Python Scripts\Tkinter.py", line , in __init__ 
    self.grid(column=0,row=0) 
    File "C:\Python34\lib\tkinter\__init__.py", line 2055, in grid_configure 
    self.tk.call( 
AttributeError: 'Page' object has no attribute 'tk' 

我是相當新的Tkinter的，而這個錯誤我難住了。我非常感謝任何幫助，謝謝！

您的Page init方法應該調用Frame的init。

class Page(tk.Frame): 
    '''Enables switching between pages of a window.''' 
    def __init__(self): 
     super(Page, self).__init__() 
     self.widgets={} 
     self.grid(column=0,row=0)
