Strange case with QStyledItemDelegate::setModelData

void GuiItemDelegate::setModelData(QWidget* widget, QAbstractItemModel* model, const QModelIndex& index) const
{
    static int string_id = qMetaTypeId<std::string>();
    QByteArray n = widget->metaObject()->userProperty().name();
    QVariant variant = widget->property(n);

    std::cout << std::string(widget->metaObject()->userProperty().typeName()) << std::endl;
    if(variant.userType() == QVariant::String && variant.userType() != QMetaType::Float) {
        std::cout << "lolwut" << std::endl;
        model->setData(index, QVariant::fromValue(variant.toString().toStdString()), Qt::EditRole);
    } else {
        QStyledItemDelegate::setModelData(widget, model, index);
    }
}
