Python-滚动条如何与标签，单选按钮，按钮一起使用？

Question

For weeks I try to get my application scrollbar. But there is a conflict with the TKinter-modules and I don't know how to fix it. Without my modules it is scrollbar but not with them. Can you help me please with this examples out of my application?

To scroll widgets inside a Canvas , instead of using the usual pack , grid or place methods to display them, you need to use the create_window method of the Canvas . The syntax of the method is canvas.create_window(x, y, window=widget, **kw) . Here you can get details about the keyword arguments.

Example:

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()
