如何在Tkinter中将事件绑定到鼠标滚轮点击(而不是滚动)？

import tkinter as tk

window = tk.Tk()

def mouse_wheel_click(event):
    # 在这里编写处理鼠标滚轮点击事件的代码
    pass

window.bind("<Button-2>", mouse_wheel_click)

window.mainloop()

import tkinter as tk

def mouse_wheel_click(event):
    # 在这里编写处理鼠标滚轮点击事件的代码
    pass

window = tk.Tk()
window.bind("<Button-2>", mouse_wheel_click)
window.mainloop()
