QCommandLineProcessor with negative numbers

mranger90

Trying to get QCommandLineParser to work with a negative floating point argument.
For example the following code wants to parse a command line of: app --auto --tilt -20.2
But QCP is trying to use the "-20.2" as an argument and complains.

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
    QCommandLineParser parser;
    parser.setApplicationDescription("Projection Reconstructor " + QString("1.0"));

    // Run in auto mode (-a, --auto) as opposed to interactive
    QCommandLineOption autoReconstructionOption(
        QStringList() << "a"
                      << "auto",
        QCoreApplication::translate("main", "Operate in automatic mode."));
    parser.addOption(autoReconstructionOption);

    QCommandLineOption tiltAngleOption(
        QStringList() << "t"
                      << "tilt",
        QCoreApplication::translate("main", "floating point tilt angle."));
    parser.addOption(tiltAngleOption);

    parser.addHelpOption();

    parser.addVersionOption();
    parser.process(app);

    const bool runAutoMode = parser.isSet(autoReconstructionOption);

    double tiltAngleValue = 0.0;
    if (parser.isSet(tiltAngleOption))
    {
        bool convertOk;
        const double angleFromCommandline = parser.value(tiltAngleOption).toDouble(&convertOk);
        if (convertOk)
        {
            tiltAngleValue = angleFromCommandline;
        }
    }

    qDebug() << "runAutoMode = " << runAutoMode << "Tilt Angle" << tiltAngleValue;
    PtoVMain w(runAutoMode);

    w.show();
    return app.exec();
}```

@mranger90 Does

 app --auto --tilt "-20.2"

work?

Tried that already, same results

Got it, had to another argument to the option


    QCommandLineOption tiltAngleOption(
        QStringList() << "t"
                      << "tilt",
        QCoreApplication::translate("main", "floating point tilt angle."),
        QCoreApplication::translate("main", "angle value"));
    parser.addOption(tiltAngleOption);
