MVC example not working

I am trying implement a MVC model, downloaded the source code from http://doc.trolltech.com/qq/qq10-mvc.html

But I can't compile, it says following:

The problem seems to be QObject::QObject(QObject*&, const char*&), the constructor doesn't have that second argument.

But that example is kind of old, because it uses headers like this: #include <qapplication.h>
//i think this is Qt3 example, but i'm not sure

You can try to port that to Qt4, or use some newer resource, like this
