Convert Custom Class to QVariant

Fuel

I read that with Q_DECLARE_METATYPE i can add Custom Classes to the accepted Templates of QVariant. But i was thinking i can return now my Custom Class to a QVariant. This is my Code.

QVariant DiaryTableModel::data(const QModelIndex &index, int role) const
{
    if (!index.isValid())
        return QVariant();

    if (role == Qt::DisplayRole)
    {
        if (index.column() == 0)
            return int(mItems.at(index.row())->Id);
        else if (index.column() == 1)
            return QString(mItems.at(index.row())->Date);
        else if (index.column() == 2)
            return StarTable(mItems.at(index.row())->Rating);
    }

    return QVariant();
}

But my Debugger says that StarTable cannot be converted to a QVariant. Why? StarTable has Q_DECLARE_METATYPE(StarTable)

QVariant::fromValue<StarTable>( starTableVar );
