python获取treeview中的值

Python可以使用treeview的get_children()方法获取treeview中所有子项的ID，然后使用item()方法获取每个子项的值。例如：

import tkinter as tk
from tkinter import ttk

root = tk.Tk()

# 创建treeview
tree = ttk.Treeview(root)
tree.pack()

# 添加子项
tree.insert("", "end", "item1", text="Item 1")
tree.insert("", "end", "item2", text="Item 2")
tree.insert("item1", "end", "subitem1", text="Subitem 1")
tree.insert("item1", "end", "subitem2", text="Subitem 2")

# 获取treeview中的值
for child_id in tree.get_children():
    child_value = tree.item(child_id)["text"]
    print(child_value)

root.mainloop()

输出结果为：

Item 1
Item 2
Subitem 1
Subitem 2
