Disable validation in QSpinBox

Question

Hence I have a QSpinBox, and want to unset validation for writing not only int values, but also string in it. Please help me to fix this. I have tried this, but it does not work:

class Spinbox:public QSpinBox
{
public:

    Spinbox(QWidget* parent=0)
        :QSpinBox(parent){}
    void setLineEdit(QLineEdit *l)
    {
        QSpinBox::setLineEdit(l);
    }
};

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    Spinbox de;
    QLineEdit le;
    le.setValidator(0);
    le.setText("text");
    de.setLineEdit(&le);
    de.show();

    return a.exec();
}

Qt docs say that:

If QLineEdit::validator() for the lineEdit returns 0, the internal validator of the spinbox will be set on the line edit.

Thus, in order to disable the QSpinBox's built in validator, you need to set your own (dummy?). I.e.

class Validator : public QValidator
{
public:
    State validate(QString &input, int &pos ) const
    {
        return QValidator::Acceptable;
    }
};

[..]

Spinbox de;
QLineEdit le;
le.setValidator(new Validator());
le.setText("text");
de.setLineEdit(&le);
de.show();
