    To practice how to write a Gui program that is relatively simple, is to link hold down on your Web site, and then double-click called MPlayer for playback:
使用pyqt的第一个程序－－北邮人IPTV客户端
   (1) get the link code (uses urllib and sgmllib library):
#! /usr/bin/env python
# -*- coding: utf-8 -*-

import urllib
import sys
from sgmllib import SGMLParser
class URLLister(SGMLParser):
    def reset(self):
        SGMLParser.reset(self)
        self.pieces=[]
        self.urls=[]
        self.data=[]
        self.flag = 0

    def start_a(self,attrs):
        href=[v for k,v in attrs if k=="href"]
        if "mms" in str(href):
            self.pieces.extend(href)
            self.flag = 1

    def end_a(self):
        self.flag = 0

    def handle_data(self,text):
        if(self.flag == 1):
            self.pieces.extend([text.decode('GB2312').encode('UTF-8')]) # (sys.stdin.encoding)])

def getplaylist():
    playlist = []
    usock=urllib.urlopen("http://iptv.bupt.edu.cn/")
    parser=URLLister()
    parser.feed(usock.read())
    usock.close()
    parser.close()

    length = len(parser.pieces)/2
    for i in range(length) :
            playlist.extend(["%s %s" % (parser.pieces[i*2+1],parser.pieces[i*2])])
    return playlist

    (2) Gui part of the code:
#! /usr/bin/env python
# -*- coding: utf-8 -*-

import sys
from PyQt4 import QtCore, QtGui
from iptv import Ui_iptv
import playlist
import string

class StartQt4(QtGui.QMainWindow):
    def __init__(self, parent=None):
        QtGui.QWidget.__init__(self, parent)
        self.ui = Ui_iptv()
        self.ui.setupUi(self)
        self.codec = QtCore.QTextCodec.codecForName('UTF-8')
        self.tvlist = playlist.getplaylist()
        self.ui.listTable.clear()
        for url in self.tvlist:
            item = QtGui.QListWidgetItem(self.ui.listTable)
            item.setText(QtGui.QApplication.translate("iptv", url, None, QtGui.QApplication.UnicodeUTF8))            
       QtCore.QObject.connect(self.ui.listTable,QtCore.SIGNAL("itemDoubleClicked(QListWidgetItem*)"),
self.play）
        QtCore.QMetaObject.connectSlotsByName(self)


    def play(self):
        import subprocess
        signalList = self.sender()
        Itemcount = signalList.currentRow()
        Itemtext = self.tvlist[Itemcount]
        url = string.split(Itemtext)[1]
        subprocess. Popen(["smplayer",url])
   
if __name__ == "__main__":
    app = QtGui.QApplication(sys.argv)
    myapp = StartQt4()
    myapp.show()
    sys.exit(app.exec_())
