python GUI tkinter滚动条不适用于画布

import tkinter as tk

root = tk.Tk()
frame = tk.Frame(root)
frame.pack()

canvas = tk.Canvas(frame)
canvas.pack(side="left", fill="both", expand=True)

scrollbar = tk.Scrollbar(frame, orient="vertical", command=canvas.yview)
canvas.configure(yscrollcommand=scrollbar.set)
scrollbar.pack(side="right", fill="y")

inner_frame = tk.Frame(canvas)
canvas.create_window((0, 0), window=inner_frame, anchor="nw")

def configure_scroll_region(event):
    canvas.configure(scrollregion=canvas.bbox("all"))

inner_frame.bind("<Configure>", configure_scroll_region)

# 添加内容到inner_frame中
