Hi,all? 
   I use QWebFrame()::setHtml() function to load a page from local file system, and this page contains some external resource,but i don't need QNetworkAccessManager to download these stuff for me,because i need to download these through my own crawler.
EG:
  <html>
    <body>
       <script src="http://www.***.com/1.js" language="javascript" type="text/javascript"></script>
       <h1>test</h1>
    </body>
  </html>

1.js:
document.write("<h1>test</h1><img src=http://www.***.com/1.jpg>")

First i use QWebFrame()::setHtml() load this page,because there is a js file need to download,so, i need qtwebkit tell me the url,and i download the js through my crawler. When the js is download,i use QWebFrame()::evaluateJavaScript() to execute it, when call  evaluateJavaScript,i need to get the url of the img.This is my  expect output :
<html>
<body>
<h1>test</h1><img src=http://www.***.com/1.jpg>
</body>
</html>

So, can anybody tell me :
1) I don't need QNetworkAccessManager to download anything, how to shutdown it?
2) When a page need to load some external resource, how to get the url?

Thanks!

You need to override QNetworkAccessManager::createRequest().
This function is called for every file requested by QtWebkit.
There you can also return a custom QNetworkReply which your crawled data.

See http://doc.qt.nokia.com/qq/32/qq32-webkit-protocols.html

Good luck!
Markus
