I spent whole day to find a Qt code to get a source code from some website(e.g. www.google.com), but everything I found, it didn't work. So, please can someone post the code how to get the source code from website? (I am using Qt creator and I don't know nothing about slot connecting, so please write the code without the slot connecting(or whatever is this) if it is even possible.

EDIT: Here is the code:

I have a file mainwindow.h and mainwindow.ui too, but I think that nobody needs those files, so I didn't post them.

#include <QDebug>
#include <QtNetwork/QNetworkAccessManager>
#include <QtNetwork/QNetworkRequest>

class MyClass : public QObject{

    Q_OBJECT

public slots:
    void onFinished() {
        QIODevice * content = static_cast<QIODevice*>(QObject::sender());
        qDebug() << content->readAll();
        content->deleteLater();
    }
};

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
    QNetworkAccessManager nam;
    MyClass obj;

    QNetworkReply * reply = nam.get(QNetworkRequest(QUrl("http://google.com")));
    QObject::connect(reply, SIGNAL(finished()), &obj, SLOT(onFinished()));

    app.exec();
}
