QtWebkit over the proxy

I wrote some posts about QtWebkit. But these may fail if your program runs behind the proxy. Then I rewrite programs in phosphorescence: QtWebkit HTML5 practice like below. Additional codes are blue characters.

Qt program

#include <QApplication>
#include <QUrl>
#include <QWebView>
#include <QNetworkProxy>

int main(int argc, char *argv[]){
   QApplication a(argc, argv);
   QNetworkProxy proxy(QNetworkProxy::HttpProxy, "proxy.host", proxy.port);
   QNetworkProxy::setApplicationProxy(proxy);
   QUrl url("http://htmlfive.appspot.com/static/draw.html");
   QWebView* webView = new QWebView();
   webView->load(url);
   webView->show();
   return a.exec();
}

QtRuby program

require 'Qt4'
require 'qtwebkit'

Qt::Application.new(ARGV) do
proxy = Qt::NetworkProxy.new(Qt::NetworkProxy::HttpProxy, "proxy.host", proxy.port)
Qt::NetworkProxy.application_proxy = proxy
Qt::WebView.new do
self.load Qt::Url.new('http://htmlfive.appspot.com/static/gifter.html')
show
end
exec
end

proxy.host and proxy.port should replace ones of your proxy environment.
