Question

我正在使用Glade，python和pygtk来开发一个非常基本的GUI，它将根据通过UDP套接字接收的实时数据进行自我更新。收到的数据包每256ms一次。据我所知，我需要使用一个线程来接收这些数据，以便在接收数据时保持我的GUI响应。我试图这样做。结果GUI打开但我没有从我的UDP（dpmserver线程）获得任何OP 。我单独尝试了dpmserver模块，它工作正常。我是线程新手。实际上这是我在python中使用线程的第一个程序。如何保持GUI响应并同时接收数据？代码如下：

TMSTART=41
PACKETSIZE=133
FIELD=9
TMEND=(PACKETSIZE-1)-FIELD
import socket
import sys
import string
import os.path
import urllib2
import string
import linecache
from pprint import pprint,pformat
import threading
try:
  import pygtk
  pygtk.require("2.0")
except:
  print "You need to install pyGTK or GTKv2 or set your PYTHONPATH correctly"
  sys.exit(1)

import gtk
import gtk.glade

def procpack(data):


        TMlist=[]
        for i in range(TMSTART,TMEND,FIELD):
                field=data[i+1:i+FIELD+1]
                try:
                        if field=='\x00\x00\x00\x00\x00\x00\x00\x00\x00':
                                return TMlist
                except:
                        pass
                TMlist.append([field[0:8],field[8]])

def dpmserver():
        server_socket = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
        server_socket.bind(("", 5123))

        print"UDPServer Waiting for client on port 5123"
        bytestack=[];
        while 1:
                data, address = server_socket.recvfrom(512)
                print "( " ,address[0], " " , address[1] , " ) said : ", data," length:",len(data)

                print procpack(data)


class AppParafin:
  def __init__(self):


        self.gladefile = 'dpm.glade'
        windowname = 'Deployment Monitor'# This must match the window name in glade
        self.wTree = gtk.glade.XML(self.gladefile, windowname)# object for acessing widgets
        t=threading.Thread(target=dpmserver)
        t.start()
        self.op=self.wTree.get_widget('Deployment Monitor')
        self.op.show()

app = AppParafin()
gtk.main()

使用python中的实时UDP数据进行GUI更新
