如何在Tkinter笔记本标签上添加悬停效果？

import tkinter as tk
from tkinter import ttk

window = tk.Tk()
notebook = ttk.Notebook(window)
notebook.pack()

tab1 = ttk.Frame(notebook)
tab2 = ttk.Frame(notebook)
notebook.add(tab1, text="Tab 1")
notebook.add(tab2, text="Tab 2")

def on_enter(event):
    tab_text = notebook.tab(notebook.select(), "text")
    notebook.tab(notebook.select(), text=tab_text + " [Hover]")

def on_leave(event):
    tab_text = notebook.tab(notebook.select(), "text")
    notebook.tab(notebook.select(), text=tab_text.replace(" [Hover]", ""))

notebook.bind("<Enter>", on_enter)
notebook.bind("<Leave>", on_leave)

window.mainloop()
