Can't compile custom QValidator

[vieraci]

Can anyone see why this doesn't compile ?

header file:

#include <QValidator>
class QvDateValidator : public QValidator
{
public:
    QvDateValidator(QObject * parent);
protected:
    void fixup ( QString & input ) const;
    QValidator::State validate ( QString & input, int & pos ) const;
};

#include <QValidator>
class QvDateValidator : public QValidator
{
public:
    QvDateValidator(QObject * parent);
protected:
    void fixup ( QString & input ) const;
    QValidator::State validate ( QString & input, int & pos ) const;
};

because (as the compiler tried to tell you) QValidator does not have a default constructor (one without args). You need to pass parent to it:

QvDateValidator::QvDateValidator(QObject * parent)
   : QValidator(parent)
{}

QvDateValidator::QvDateValidator(QObject * parent)
   : QValidator(parent)
{}
