    Read Qt Assistant about QNetworkAccessManager. I think it will help you.

      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()));
                        }@
