How to exit Qt console application?

[neuronet]

If you don't need an event loop then just don't call QCoreApplication::exec().

Would you even need the

QCoreApplication a(argc, argv);

QCoreApplication a(argc, argv);

To copy to clipboard, switch view to plain text mode 

line in that case? I'm having similar confusion as I recently wrote about here:
How to control a pure console application
I still don't feel like I understand how to properly initialize/kill/execute console applications in PyQt/PySide.
