Tkinter :如何限制用户使用多个功能

button = tkinter.Button(root, text="Click me", state=tkinter.DISABLED)

import tkinter

def toggle_button():
    if checkbox_var.get():
        button.config(state=tkinter.NORMAL)
    else:
        button.config(state=tkinter.DISABLED)

root = tkinter.Tk()

checkbox_var = tkinter.BooleanVar()
checkbox = tkinter.Checkbutton(root, text="Enable button", variable=checkbox_var, command=toggle_button)
checkbox.pack()

button = tkinter.Button(root, text="Click me", state=tkinter.DISABLED)
button.pack()

root.mainloop()
