Python:如何在tkinter窗口中显示Twisted reactor接收到的UDP消息？

import tkinter as tk
from twisted.internet import reactor, protocol

class App(tk.Frame):
    def __init__(self, master=None):
        super().__init__(master)
        self.pack()
        
        self.textbox = tk.Text(self)
        self.textbox.pack()

class UDPProtocol(protocol.DatagramProtocol):
    def __init__(self, app):
        self.app = app
        
    def datagramReceived(self, data, addr):
        message = data.decode()
        self.app.textbox.insert(tk.END, message + '\n')

if __name__ == '__main__':
    root = tk.Tk()
    app = App(master=root)
    udp_protocol = UDPProtocol(app)

    reactor.listenUDP(1234, udp_protocol)
    reactor.run()

import tkinter as tk
from twisted.internet import reactor, protocol

class App(tk.Frame):
    def __init__(self, master=None):
        super().__init__(master)
        self.pack()
        
        self.textbox = tk.Text(self)
        self.textbox.pack()

class UDPProtocol(protocol.DatagramProtocol):
    def __init__(self, app):
        self.app = app
        
    def datagramReceived(self, data, addr):
        message = data.decode()
        self.app.textbox.insert(tk.END, message + '\n')

if __name__ == '__main__':
    root = tk.Tk()
    app = App(master=root)
    udp_protocol = UDPProtocol(app)
    
    reactor.listenUDP(1234, udp_protocol)
    reactor.run()
