CLI and QCoreApplication - where to start?

[soul_rebel]

I want to write a little program with a CLI. How do I actually implement this?
The Tutorials/examples were not really about CLIs and searching didnt help me yet...

main.cpp:

#include <QCoreApplication>
#include "myapp.h"
 
int main(int argc, char *argv[])
{
      QCoreApplication app(argc, argv);
      MyApp *realApp = new MyApp(argc,argv);
      return realApp->run();
}

#include <QCoreApplication>
#include "myapp.h"

int main(int argc, char *argv[])
{
      QCoreApplication app(argc, argv);
      MyApp *realApp = new MyApp(argc,argv);
      return realApp->run();
}

To copy to clipboard, switch view to plain text mode 

doesnt look good, because no eventloop is created...
should i instead let myapp inherit QCoreApplication and just reimplement myapp::exec() to do what i want it to?
Or what is the "right" way to do it?

Thank you very much for your help!
