Passing Command line arguments to a Qt application in linux

[payal]

Hi all,

I have a Qt application for which i have to pass some command line arguements to make it execute..is there any way to set the command line arguements programatically?

How can i achieve this?Anyone, plz help me in this regard.............

Is it possible to mention command line arguements while executing itself?

Do you want to execute an application passing some arguments? Look at QProcess::start.
Do you want to get arguments passed to your application? Look at QCoreApplication::arguments.

yes payal , you can pass arguments from cmd line,

ex

int main(int argc, char *argv[])
{
    QCoreApplication app(argc, argv);
    QStringList args = app.arguments();
    if (args.count() != 2) 
    {
 
        std::cerr << "argument required" << endl;
          return 1;
    }
    myClass m;   //ur class 
    m.test(args[1]);   //pass cmd argument as function argument.
    return app.exec();
}

int main(int argc, char *argv[])
{
    QCoreApplication app(argc, argv);
    QStringList args = app.arguments();
    if (args.count() != 2) 
    {

        std::cerr << "argument required" << endl;
          return 1;
    }
    myClass m;   //ur class 
    m.test(args[1]);   //pass cmd argument as function argument.
    return app.exec();
}
