How do I know that QProcess has finished?

[NTCYP]

Hi,

In my app I connect to wifi hotspot. And I use ping option to check if the connection is okay as shown below code?

// Create QProcess object
        proc = new QProcess();
        proc->start("ping", QStringList() << "-c" << "3" << QString(m_sHostName));

        // Show output
        connect(proc, SIGNAL(readyReadStandardOutput()), this, SLOT(rightMessage()));
        connect(proc, SIGNAL(readyReadStandardError()), this, SLOT(wrongMessage()));

        ui->TextEditResult->setTextColor(Qt::white);
        QCoreApplication::processEvents();

Now I need to know if the QProcess has finished. If finished I have another job to do.
So can I use below code to terminate my QProcess before doing another job?

    if(proc->waitForFinished(3) == true)
    {
        proc->terminate();
       // Messagebox that QProcess has just terminated. (kill)
       ....
       ....
       ....

      // Do other job
    }

Use the finished signal: http://doc.qt.io/qt-5/qprocess.html#finished
