如何用tkinter创建一个聊天窗口？

import tkinter as tk

root = tk.Tk()
root.title("聊天窗口")

chat_window = tk.Text(root)
chat_window.pack()

input_frame = tk.Frame(root)
input_frame.pack(side=tk.BOTTOM)

input_box = tk.Entry(input_frame)
input_box.pack(side=tk.LEFT)

send_button = tk.Button(input_frame, text="发送")
send_button.pack(side=tk.LEFT)

def send_message():
    message = input_box.get()
    chat_window.insert(tk.END, "我: " + message + "\n")
    input_box.delete(0, tk.END)

send_button.config(command=send_message)

root.mainloop()
