title: How to make request through proxy in PyQt4
body: <p>I want to make a request through a HTTP proxy, the thing is I don't really understand how to set it up.</p>
  
  <p>Here is an example code:</p>
  
  <pre><code>#! /usr/bin/env python2.7
  
  from PyQt4.QtCore import *
  from PyQt4.QtGui import *
  from PyQt4.QtWebKit import *
  from bs4 import BeautifulSoup
  import sys
  
  class MySettings(QWebPage):
      def __init__(self):
          QWebPage.__init__(self)
          self.settings().setAttribute(QWebSettings.AutoLoadImages, False)
  
  class Browser(QWebView):
      def __init__(self):
          QWebView.__init__(self)
          self.setPage(MySettings())
          self.loadProgress.connect(self._progress)
          self.loadFinished.connect(self._loadFinished)
          self.doc = self.page().currentFrame()
  
      def _progress(self, progress):
          print progress
  
      def _loadFinished(self):
          html = unicode(self.doc.toHtml()).encode('utf-8')
          soup = BeautifulSoup(html[1000])
          print soup.prettify()
  
  if __name__ == "__main__":
      app = QApplication(sys.argv)
      br = Browser()
      url = QUrl('http://http://ip2location.com/')
      br.load(url)
      br.show()
      app.exec_()
  </code></pre>
  
  <p>I have read about the QNetworkAccessManager class but don't understand where should I put it or should I create a different class like I did with QWebPage like so:</p>
  
  <pre><code>class MyNetworkAccessManager(QNetworkAccessManager):
      def __init__(self):
          QNetworkAccessManager.__init__(self)
          proxy = QNetworkProxy('HTTP','127.0.0.1', '8080') 
          self.setProxy(proxy)
  </code></pre>
  
  <p>If so, how to make my Browser(QWebView) class use MyNetworkAccessManager,</p>
  
  <p>or may be I'm tottaly wrong, and it should be done differently.</p>
  
  <p>Thank you very much for any help.</p>
