Tkinter可以识别在treeview中选择了哪个标题吗？

import tkinter as tk
from tkinter import ttk

def on_select(event):
    selected_item = treeview.focus()
    selected_title = treeview.item(selected_item)['text']
    print("Selected title:", selected_title)

root = tk.Tk()

treeview = ttk.Treeview(root)
treeview.pack()

# 添加标题
treeview.heading("#0", text="Title 1")
treeview.heading("#1", text="Title 2")
treeview.heading("#2", text="Title 3")

# 添加数据
treeview.insert("", "end", text="Item 1", values=("Value 1", "Value 2", "Value 3"))
treeview.insert("", "end", text="Item 2", values=("Value 4", "Value 5", "Value 6"))

# 绑定选择事件
treeview.bind("<<TreeviewSelect>>", on_select)

root.mainloop()
