如何在Tkinter中更改悬停按钮的背景色？

hover_bg_color = "red"  # 悬停时的背景色
normal_bg_color = "blue"  # 普通状态下的背景色

button = tk.Button(root, text="按钮", bg=normal_bg_color)
button.pack()

def on_enter(event):
    button.config(bg=hover_bg_color)

button.bind("<Enter>", on_enter)

def on_leave(event):
    button.config(bg=normal_bg_color)

button.bind("<Leave>", on_leave)

import tkinter as tk

root = tk.Tk()

hover_bg_color = "red"  # 悬停时的背景色
normal_bg_color = "blue"  # 普通状态下的背景色

button = tk.Button(root, text="按钮", bg=normal_bg_color)
button.pack()

def on_enter(event):
    button.config(bg=hover_bg_color)

def on_leave(event):
    button.config(bg=normal_bg_color)

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

root.mainloop()
