    The value of databasePathOption command line option in the code below is always empty:

    int main(int argc, char* argv[])
    {
        QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling);
    
        QGuiApplication app(argc, argv);
        QCoreApplication::setApplicationVersion("1.0");
        QCoreApplication::setApplicationName("MyApp");
    
        QCommandLineParser parser;
        parser.setApplicationDescription("My App");
        parser.addHelpOption();
        parser.addVersionOption();
        QCommandLineOption databasePathOption(QStringList() << "x" << "db123", QCoreApplication::translate("main", "Program database file path."));
        parser.addOption(databasePathOption);
        parser.process(app);
    
        QString val = parser.value(databasePathOption);
        qDebug() << "db=" << val;
       ...
    }
    

    I start the program with the following arguments:

    --db123 "asdf"
    

    but it prints an empty string.

    What did I do wrong?

      Hi,

      From the documentation, you are missing the valueName parameter.
