How to create a console application with command line arguments in Qt?

[Guerrian]

I have looked at this online and seen various approaches such as using QApplication or QCoreApplication. I would like to use Qt objects for the application and parse the command line. For example to parse a command line such as:

myapp -foo bar -qaz 10

Which approach is best?

@Guerrian
You can pick whichever kind of QApplication is best for your program, and you can access command-line arguments either via QCoreApplication::arguments() (if you don't need a GUI) or other Qt classes, or from the C++ main(argc, argv) as you please.

Qt has for this a adequately named class QCommandLineParser

Might be helpful 😉

@Guerrian hi

for (int i = 1; i < argc; i++) {
       qDebug() << "param" << i << " is " << argv[i];
     }

Hi,

there is a QCommandLineParser-class. (https://doc.qt.io/qt-5/qcommandlineparser.html#details)
Have a look at this.

Edit:
Damn, I'm typing too slow... :) @J-Hilk
