将treeview子级传输到tkinter中的另一个treeview

import tkinter as tk
from tkinter import ttk

root = tk.Tk()

source_treeview = ttk.Treeview(root)
target_treeview = ttk.Treeview(root)

source_treeview.pack()
target_treeview.pack()

# 添加根节点
root_node = source_treeview.insert("", "end", text="Root")

# 添加子节点
child_node = source_treeview.insert(root_node, "end", text="Child")

# 设置节点标识符
source_treeview.set(child_node, "id", "1")

def get_selected_children():
    selected_items = source_treeview.selection()
    children_data = []

    for item in selected_items:
        children = source_treeview.get_children(item)
        for child in children:
            child_data = source_treeview.item(child, "values")
            children_data.append(child_data)

    return children_data

def add_children_to_target():
    children_data = get_selected_children()

    for data in children_data:
        target_treeview.insert("", "end", values=data)

button = tk.Button(root, text="Transfer", command=add_children_to_target)
button.pack()
