int ExactnessConfigurator::qt_metacall(QMetaObject::Call _c, int _id, void **_a)
{
    _id = QWidget::qt_metacall(_c, _id, _a);
    if (_id < 0)
        return _id;

        switch (_id) {
        case 0: addCurrentValue(); break;
        case 1: removeCurrentValue(); break;
        case 2: updateValueFromItem((*reinterpret_cast< QTableWidgetItem*(*)>(_a[1]))); break;
        default: ;
