Python - 滚动条如何处理标签，单选按钮，按钮？

Question

几周来，我尝试让我的应用程序滚动条。但是与TKinter模块有冲突，我不知道如何解决它。没有我的模块，它是滚动条，但不是与他们。你可以帮我请一下这个例子吗？

Ps。请好，我是一个半新手。 ：/：p PP。我没有textdefinitions代码和所有单选按钮

要滚动Canvas内部小部件，而不是使用通常的pack，grid或place方法来显示它们，你需要使用Canvas的create_window方法。该方法的语法是 canvas.create_window(x, y, window=widget, **kw)。 Here你可以得到有关关键字参数的细节。

例子：

import tkinter as tk 

root = tk.Tk() 

canvas = tk.Canvas(root) 
scrolly = tk.Scrollbar(root, orient='vertical', command=canvas.yview) 

# display labels in the canvas 
for i in range(10): 
    label = tk.Label(canvas, text='label %i' % i) 
    canvas.create_window(0, i*50, anchor='nw', window=label, height=50) 

canvas.configure(scrollregion=canvas.bbox('all'), yscrollcommand=scrolly.set) 

canvas.pack(fill='both', expand=True, side='left') 
scrolly.pack(fill='y', side='right') 

root.mainloop()
