    Use "QNetworkAccessManager":http://doc.qt.nokia.com/4.7/qnetworkaccessmanager.html . QNetworkReply inherits QIODevice and I think you should be able to go from there.

        Not tested, but:
        @
        class MyClass : public QObject
        {
        Q_OBJECT
        public:
        MyClass(QObject *parent = 0) : QObject(parent), manager(new QNetworkAccessManager)
        {
        reply = manager->get(QNetworkRequest(QUrl("http://example.com")));
        connect(reply,SIGNAL(finished()),SLOT(downloaded()));
        }

        public slots:
        void downloaded()
        {
        QFile file("/path/to/file");
        file.open(QIODevice::WriteOnly);
        file.write(reply.readAll());
        file.close();
        }

        private:
        QNetworkAccessManager *manager;
        QNetworkReply *reply;
        }
        @

        EDIT: fixed example

                Use QProgressDialog or implement one by yourself. Qt Assitant and Qt examples contain all info that you need. Try to use them.

                    i insert this in the mainwindows.cpp:
                    @
                    MainWindow(QMainWindowparent = 0) : QMainWindow(parent), manager(new QNetworkAccessManager)
                    {
                    reply = manager->get(QNetworkRequest(QUrl("http://example.com")));
                    connect(reply,SIGNAL(finished()),SLOT(downloaded()));
                    }
                    @
                    and i get an error: C:\Users\zanotti\aaa-build-desktop..\aaa\mainwindow.cpp:29: error: expected ')' before '=' token

                      It should be more like:
                      @MainWindow::MainWindow(QWidget *parent = 0) : QMainWindow(parent), manager(new QNetworkAccessManager)
                      {
                      reply = manager->get(QNetworkRequest(QUrl("http://example.com")));
                      connect(reply,SIGNAL(finished()),SLOT(downloaded()));
                      }@
