    Show processing on console app
    Ex:

    Processing.
    Processing..
    Processing...
    

    OR

    Process: 10%
    Process: 15%
    Process: 20%
    .....
    Done
    

    But all text only one line, older text is removed.

        You can do it with something like:

        for(unsigned short int i = 0; i <= 100; i++) {
        	std::cout << QString("\rProgress: %1").arg(
        		i < 100 ? QString("%1%").arg(i) : "Done"
        	).toStdString() << std::flush;
        	std::this_thread::sleep_for(std::chrono::milliseconds(50));
        }
        

        Libraries needed to run this example: iostream, thread and chrono
