Python QWebView: Доступ к сетевым ресурсам

Question

Я пытаюсь получить доступ к сети запрос URLs с QNetworkAccessManager

Из этого примера Threading with webkit, я приложил NetWorkAccessManager к существующему коду, но страница просто не загружается с моим код.

import sys 
from collections import deque # threadsafe datatype 
from PyQt4.QtCore import * 
from PyQt4.QtGui import * 
from PyQt4.QtWebKit import * 
from PyQt4.QtNetwork import * 
NUM_THREADS = 2 # how many threads to use 

class Render(QWebView): 
    active = deque() # track how many threads are still active 
    data = {} # store the data 

    def __init__(self, urls): 
     QWebView.__init__(self) 

     # I have Added the following code 
     manager = Manager() 
     page = self.page() 
     page.setNetworkAccessManager(manager) 

     self.loadFinished.connect(self._loadFinished) 
     self.urls = urls 
     self.crawl() 

    def crawl(self): 
     try: 
      url = self.urls.pop() 
      print 'downloading', url 
      Render.active.append(1) 
      self.load(QUrl(url)) 
     except IndexError: 
      # no more urls to process 
      if not Render.active: 
       # no more threads downloading 
       print 'finished' 
       self.close() 

    def _loadFinished(self, result): 
     # process the downloaded html 
     frame = self.page().mainFrame() 
     url = str(frame.url().toString()) 
     Render.data[url] = frame.toHtml() 
     Render.active.popleft() 
     self.crawl() # crawl next URL in the list 

# I have Added the following class 
class Manager(QNetworkAccessManager): 
    def __init__(self): 
     print 'entered network manager' 
     QNetworkAccessManager.__init__(self) 
     self.finished.connect(self._finished) 

    def _finished(self, reply): 
     print 'finished network req event' 
     url = reply.url().toString() 
     print url.toUtf8() 

app = QApplication(sys.argv) # can only instantiate this once so must move outside class 
urls = deque(['http://www.google.com/', 'http://stackoverflow.com/']) 
renders = [Render(urls) for i in range(NUM_THREADS)] 
app.exec_() # will execute qt loop until class calls close event 

Что я здесь делаю неправильно?

Необходимо только добавить self.setPage(page) Перед установкой page.setNetworkAccessManager(manager)
