是否刷新整个tkinter gui？

import tkinter as tk

def update_label():
    label.config(text="New Text")

root = tk.Tk()
label = tk.Label(root, text="Initial Text")
label.pack()

button = tk.Button(root, text="Update Label", command=update_label)
button.pack()

root.mainloop()

import tkinter as tk

def refresh_gui():
    for widget in root.winfo_children():
        widget.destroy()
    create_new_gui()

def create_new_gui():
    new_label = tk.Label(root, text="Refreshed Text")
    new_label.pack()
    new_button = tk.Button(root, text="Refresh Again", command=refresh_gui)
    new_button.pack()

root = tk.Tk()
create_new_gui()

root.mainloop()
