Here's an example of how you might do it using Twisted
from twisted.internet import protocol, reactor, tksupport
from twisted.application import service, internet
import Tkinter as Tk
class TkDisplayProtocol(protocol.DatagramProtocol):
def __init__(self, root):
self.root = root
self.frame = Tk.Frame(self.root)
self.frame.pack()
self.label = Tk.Label(self.frame)
self.label.pack()
tksupport.install(self.root)
def datagramReceived(self, data, addr):
self.label.configure(text=repr(data))
application = service.Application('UDP/Tk')
internet.UDPServer(
12345,
TkDisplayProtocol(Tk.Tk())).setServiceParent(application)
Save to "udptk.tac" and run using "twistd -noy udotk.tac".
