Question

I am validating my TextBox to take only numbers between 1-75.
I am able to do this by using below code :

QValidator *validator = new QIntValidator(1, 75, this);
QLineEdit *edit = new QLineEdit(this);
edit->setValidator(validator);

But now the problem is it takes zero also. I want to avoid Zero
Any help is appreciated.

Answer 1

you can write your validator like that:

 class lvalidator : public QValidator
    {
        Q_OBJECT
    public:
        explicit lvalidator(QObject *parent = 0);
        virtual State validate ( QString & input, int & pos ) const
        {
            if (input.isEmpty())
                return Acceptable;

            bool b;
            int val = input.toInt(&b);

            if ((b == true) && (val > 0) && (val < 76))
            {
                return Acceptable;
            }
            return Invalid;
        }
    };
