尝试使用API函数将从文件中提取的图标设置为TreeView Node.Image

import ctypes
from tkinter import *
from tkinter.ttk import *

# 从文件中提取图标
def extract_icon(file_path):
    shell32 = ctypes.windll.shell32
    icon_index = 0
    large_icon = shell32.ExtractIcon(None, file_path, icon_index)
    small_icon = shell32.ExtractIcon(None, file_path, icon_index)
    return large_icon, small_icon

# 创建一个带图标的 TreeView
def create_treeview_with_icon():
    root = Tk()
    treeview = Treeview(root)
    
    # 提取图标
    icon_path = "file_path"
    large_icon, small_icon = extract_icon(icon_path)
    
    # 创建 ImageList
    image_list = ImageList()
    large_icon_index = image_list.add(icon_path, icon=large_icon)
    small_icon_index = image_list.add(icon_path, icon=small_icon)
    
    # 设置 TreeView 的图标
    treeview.config(image=image_list)
    treeview.tag_configure("icon", image=large_icon_index)
    
    # 创建节点并设置图标
    node = treeview.insert("", "end", text="Node", tags=("icon",))
    
    root.mainloop()
