To copy to clipboard, switch view to plain text mode 

The first one doesn't make sense. You want to call a function, not declare one.

The second one is a function call, but you are passing a type as the argument instead of a value.
Since that would not work in Java either I have now serious doubts that you have even programmed a single line in Java as well.

There is also run-time error with the argument of walk(pp) - so should I understand that I need just walk()?
QString p="C:\\C";
Object::connect: No such slot Lister::walk(pp) in ..\Filewalker2\main.cpp:32

That has been already been answered several times.
