QCommandLineParser exit on parse()

moravas

Hi Folks,

can anybody tell me, what's the right way for using QCommandLineParser?
I tried this:
QCommandLineParser _parser;
_parser.addHelpOption();
qDebug() << _parser.addOption(QCommandLineOption(QStringList() << "p" << "port"));
_parser.process(QCoreApplication::arguments());

I start the debugger with this simple command line option: --port=65000 and I'm getting back "Unexpected value after '--port' "

What did I wrong?

Regards,
Norbert

Replace = by a blank: --port 65000

I tested "--port 65000", parse() has been done without exit, but calling "_parser.value("port")" is empty. It seems, that I cannot put value via the command line option.

You can, check the example in the documentation: http://doc.qt.io/qt-5/qcommandlineparser.html

Hi,

well, I think, I isoleted something:

if I'm using the examples, and create an option: QCommandLineOption port(QStringList() << "p" << "port", "Write generated data into <file>.", "file"); it works well.
if I create the option by this way: QCommandLineOption port("port", "declare port");, than the application exits.

Any other things are stayed unchanged.

Hi,

Can you show your complete parser related code ?
