registered class QHostAddress wrapped in QVariant?

[6thC]

How do I unwrap the QVariant from QHostAddress?

I register with:

qRegisterMetaType<QHostAddress>("QHostAddress");

I wish to intercept a c++ signal

void readyData(const qint64 &msSinceEpoch, const QByteArray &data, const QHostAddress &address, const quint16 port);

and slot to QML:

Connections { target:  ReceiverCpp;
   onReadyData: networkDiagWindow.readyDataMessage(msSinceEpoch, data, address.toString(), port);

qml Window object networkDiagWindow has:

function  readyDataMessage(msSinceEpoch, data, address, port){ 
            print (msSinceEpoch, data.toString(), address , port);

Which outputs everything as string or numbers correctly except for address it ouputs exactly:
QVariant(QHostAddress)

How do I unrawp this QVariant and get at just my object? I've looked for a QML HostAddress but doesn't seem to exist.
