Quick Learning QtWebKit

After installing Qt-Creator, build the shipped example webkit/fancybrowser.
By default, the application doesn’t use any proxy setting even you have a
http_proxy environment variable.

First, adding QtNetwork library into the project manifest file.

fancybrowser.pro
QT += webkit network

Then, modify the source code to add QNetworkProxy class for proxy support.

#include <QtNetwork>
QT_BEGIN_NAMESPACE 
class QNetworkProxy;
QT_END_NAMESPACE
int main(int argc, char* argv[]){
....
QNetworkProxy proxy(QNetworkProxy::HttpProxy, "proxy.host.com", 80);
QNetworkProxy::setApplicationProxy(proxy);
....
}
