How to send INPUT & receive OUTPUT : Calling Python from C++:

[ahsan737]

Greetings,

I am executing the following code to call python script from c++ using QProcess.

    QString path = "C:/pythonCPP";
    QString  command("python");
    QStringList params = QStringList() << "pyemb3.py";
    QProcess *process = new QProcess();
    process->startDetached(command, params, path);
    process->waitForFinished();
    process->close();

My question is how can I provide input parameters to and receive the output of python script being called.

I've skimmed through different forums/references/portals but couldn't get an understandable answer.

Looking forward to your kind responses.

Best Regards,
Ahsan

Don't use startDetached() and don't call waitForFinished().
