[PyQt] change values for javascript

[Peter Irbizon]

here is my python code for simple webbrowser I found on internet

    def userAgentForUrl(self, url):
        #~ return self.user_agent
        return QString(QByteArray(self.user_agent))

    def javaScriptAlert(self, frame, message):
        """Override default javascript alert popup
        """
        print 'Alert:', message

class IEWinApp:

  self.url=url
  self.REGEXPS = \

  for cookiename,cookievalue in self.REGEXPS['cookie'].findall(cookie_input):

      self.cookies.append(cookie_tmp)

  self.webView.setPage(self.page)
  self.webView.settings().setAttribute(QtWebKit.QWebSettings.PluginsEnabled,True)

  self.webView.show()
def on_ssl_errors(reply, errors):
   url = unicode(reply.url().toString())
   reply.ignoreSslErrors()
   print "SSL certificate error ignored: %s" % url

if __name__ == "__main__":

 url= "http://facebook.com"

 sys.exit( app.exec_() )

I am trying to make webbrowser and change values for Javascript - when
javascript print values

navigator.platform
navigator.appCodeName
navigator.appName
navigator.appVersion
navigator.productand screen values colorDepth, pixelDepthand getTimezoneOffset()

Problem is, javascript detects default system values for these properties
but I need to set it in python code so it will not print default system
values. Thank you!

I saw here, that I should execute this
http://stackoverflow.com/questions/2166540/how-can-i-fool-a-site-that-looks-at-the-javascript-object-navigator-to-see-thabefore
document loads but I don't know how. Please help
