QCommandLineOption:如何多次解析同一个参数？

#include <QCoreApplication>
#include <QCommandLineParser>
#include <QDebug>

int main(int argc, char *argv[])
{
    QCoreApplication app(argc, argv);

    QCommandLineParser parser;
    parser.setApplicationDescription("My Application");

    QCommandLineOption verboseOption("v", "Enable verbose mode.");
    parser.addOption(verboseOption);

    parser.process(app);

    bool verboseEnabled = parser.isSet(verboseOption);

    qDebug() << "Verbose mode:" << verboseEnabled;

    QStringList positionalArguments = parser.positionalArguments();
    qDebug() << "Positional arguments:" << positionalArguments;

    return app.exec();
}
