如何在打开tkinter保存文件对话框时隐藏tkinter窗口？

import tkinter as tk

root = tk.Tk()

def hide_window():
    root.withdraw()

hide_button = tk.Button(root, text="隐藏窗口", command=hide_window)
hide_button.pack()

from tkinter import filedialog

def open_save_dialog():
    file_path = filedialog.asksaveasfilename()
    root.deiconify()  # 恢复主窗口显示

open_button = tk.Button(root, text="打开保存对话框", command=open_save_dialog)
open_button.pack()

root.mainloop()
