A Qt widget designed to give a nice looking but traditional hex view.

Basic usage is trivial. Any QIODevice can be a data source for the widget. For example:

#include "QHexView"
#include <QApplication>
#include <QFile>

int main(int argc, char *argv[]) {
    QApplication app(argc, argv);

    QHexView w;
    QFile file(argv[1]);
    file.open(QIODevice::ReadOnly);

    w.setData(&file);
    w.show();
    app.exec();
    return 0;
}

This is a complete program which will display in a nice hex view, the contents of a file.
