Tkinter滚动条不适用于画布内的对象

import tkinter as tk

root = tk.Tk()
scrollbar = tk.Scrollbar(root)
scrollbar.pack(side=tk.RIGHT, fill=tk.Y)

scrollable_frame = tk.Frame(root)
scrollable_frame.pack()

# 设置滚动区域的大小
scrollable_frame.bind("<Configure>", lambda e: canvas.configure(scrollregion=canvas.bbox("all")))

# 创建画布并将其放置在滚动区域内
canvas = tk.Canvas(scrollable_frame, yscrollcommand=scrollbar.set)
canvas.pack(side=tk.LEFT, fill=tk.BOTH, expand=True)

# 将滚动条与画布关联起来
scrollbar.config(command=canvas.yview)

# 在画布内添加文本
canvas.create_text(50, 50, text="Hello, World!", anchor=tk.NW)

# 在画布内添加图像
image = tk.PhotoImage(file="image.png")
canvas.create_image(0, 0, image=image, anchor=tk.NW)

# 启用滚动功能
canvas.bind("<Configure>", lambda e: canvas.configure(scrollregion=canvas.bbox("all")))

# 将滚动区域放置在主窗口内
scrollable_frame.place(x=0, y=0, relwidth=1, relheight=1)
