QSocketNotifier Qt 4.5 Windows

[bunjee]

Hey trolls,
Consider the following code:

socketNotifier = new QSocketNotifier(0, QSocketNotifier::Read, q);
    socketNotifier->setEnabled(true);
 
    QObject::connect(socketNotifier, SIGNAL(activated(int)), q, SLOT(onReadyRead()));
 
    QFile file;
    if (file.open(0, QFile::WriteOnly) == true)
    {
        QTextStream stream(&file);
        stream << "lol";
        file.close();
    }

socketNotifier = new QSocketNotifier(0, QSocketNotifier::Read, q);
    socketNotifier->setEnabled(true);

    QObject::connect(socketNotifier, SIGNAL(activated(int)), q, SLOT(onReadyRead()));

    QFile file;
    if (file.open(0, QFile::WriteOnly) == true)
    {
        QTextStream stream(&file);
        stream << "lol";
        file.close();
    }

My onReadyRead() slot never gets called.

Why ?
