我将您的列表框更改为可滚动的框架。

如果您希望能够像在列表框中一样选择项目，您可以将标签更改为按钮。

如果您想设置滚动条的样式， ttk 会有所帮助。

我重用了这里的代码

from tkinter import *
root = Tk()
root['bg'] = 'wheat'


frame_container=Frame(root, width = 1000)
frame_container['bg'] = 'wheat'
canvas_container=Canvas(frame_container, width = 1000)
canvas_container['bg'] = 'wheat'


frame2=Frame(canvas_container, width = 1000)
frame2['bg'] = 'wheat'

scrollbar_tk = Scrollbar(frame_container, orient="vertical",command=canvas_container.yview)#, yscrollcommand=scrollbar_tk.set
 # will be visible if the frame2 is to to big for the canvas
canvas_container.create_window((0,0),window=frame2,anchor='nw')
