无法在tkinter中使用画布上的滚动(布局在网格系统中)？

import tkinter as tk

def scroll_x(*args):
    canvas.xview(*args)
    frame.xview(*args)

def scroll_y(*args):
    canvas.yview(*args)
    frame.yview(*args)

root = tk.Tk()

canvas = tk.Canvas(root)
canvas.grid(row=0, column=0, sticky="nsew")

scrollbar_x = tk.Scrollbar(root, orient="horizontal", command=scroll_x)
scrollbar_x.grid(row=1, column=0, sticky="ew")

scrollbar_y = tk.Scrollbar(root, orient="vertical", command=scroll_y)
scrollbar_y.grid(row=0, column=1, sticky="ns")

canvas.configure(xscrollcommand=scrollbar_x.set, yscrollcommand=scrollbar_y.set)

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

# 在框架中添加需要滚动的内容
label = tk.Label(frame, text="这是一个滚动的标签")
label.pack()

# 添加更多内容...

# 更新画布的滚动区域
frame.update_idletasks()
canvas.configure(scrollregion=canvas.bbox("all"))

root.mainloop()
