??? Category: Python
??? 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的第一個程序－－北郵人IPTV客戶端
?? (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_())
