你不能滚动 所以我们使用了一个虚拟画布.我们将框架放在画布内，这样当我们滚动画布时，看起来就像是在滚动框架.我们还必须绑定到用户滚动和正在更改的滚动条.

You can't scroll <tkinter.Frame> so we use a dummy canvas. We put the frame inside the canvas so that when we scroll the canvas it looks like we are scrolling the frame. We also have to bind to the user scrolling and the scrollbar being changed.

如果你想把它作为一个类:

If you want it as a class:

import tkinter as tk


FIT_WIDTH = "fit_width"
FIT_HEIGHT = "fit_height"


class ScrollableFrame(tk.Frame):
    """
    There is no way to scroll <tkinter.Frame> so we are
    going to create a canvas and place the frame there.
    Scrolling the canvas will give the illution of scrolling
    the frame
