有没有办法在tkinter树视图中重置索引？

import tkinter as tk
from tkinter import ttk

def reset_index():
    treeview.selection_clear()

root = tk.Tk()

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

# 添加一些示例数据
treeview.insert("", "end", text="Item 1")
treeview.insert("", "end", text="Item 2")
treeview.insert("", "end", text="Item 3")

# 设置选中的索引
treeview.selection_set(treeview.get_children())

reset_button = tk.Button(root, text="重置索引", command=reset_index)
reset_button.pack()

root.mainloop()
