#include  //Provides STDIN_FILENO

ConsoleReader::ConsoleReader(QObject *parent) :
    QObject(parent),
    notifier(STDIN_FILENO, QSocketNotifier::Read)
{
    connect(¬ifier, SIGNAL(activated(int)), this, SLOT(text()));
}

void ConsoleReader::text()

    QString line = qin.readLine();
    emit textReceived(line);
}

{
    Q_OBJECT

    explicit ConsoleReader(QObject *parent = 0);

    void textReceived(QString message);

    void text();

    QSocketNotifier notifier;
};
