[Qt-interest] unsigned int QSpinBox

[OJ]

I have successfully made a QSpinBox show hex numbers. The problem is
that I need it to support lager numbers than 'int' ('unsigned int'
would be sufficient). Does anyone have a tips on how I can do this
easily? This is my code:

hexspinbox.cpp:
#include <QtGui>

#include "hexspinbox.h"

HexSpinBox::HexSpinBox(QWidget *parent) : QSpinBox(parent) { }

int HexSpinBox::valueFromText(const QString &text) const
{
    bool ok;
    return text.toInt( &ok, 16 );
}

QString HexSpinBox::textFromValue(int value) const
{
    return "0x" + QString::number(value,16).toUpper();
}


hexspinbox.h:
#ifndef __HEXSPINBOX_H__
#define __HEXSPINBOX_H__

#include <QSpinBox>

class HexSpinBox : public QSpinBox
{
    Q_OBJECT
    public:
        HexSpinBox(QWidget *parent = 0);

        //TODO: overload the default int to unsigned int
        int valueFromText(const QString &text) const;
        QString textFromValue(int value) const;
};

#endif // __HEXSPINBOX_H__
