QCoreApplication

[Morea]

Oh, sorry, it shouldn't be SimpleGUI, it should be something "SimpleClass". No GUI att all.

Oh, then it is OK.
But don't forget that in console mode you must( sometimes ) make good use of the arguments passed to your app.

It will work.
I assume ai->doStuff() is a wrapper for more complicated stuff.

A Qt console app is not much different than a standard C++ console app.
