QT dont play sound if its already playing?

How can I make sure that a sound does not start to play if another one is already playing?

Im using the following code to play sounds:

void MainWindow::displayNotification(QString message)
{    
    // Play sound notification
    QSound *sound = new QSound("://2_1.wav", this);
    sound->play();
}

Any ideas?

the class "QSound" has the method "isFinished()" for that reason.

if(m_pSound->isFinished())
    //play
else
    //wait

Store a pointer to the playing QSound in your MainWindow, then check if it has finished with the isFinished function.

void MainWindow::MainWindow(QWidget* parent)
    : QMainWindow(parent)
{
    QString audiofile("://2_1.wav");
    m_pSound = new QSound(audiofile, this);
    if(!m_pSound)
    {
        qDebug() << "Failed to initialise sound file: " << audiofile;
    }
}

void MainWindow::displayNotification(QString message)
{    
    if(!m_pSound) // check m_pSound is initialised
        return;

    // check if sound is playing
    if(!m_pSound->isFinished)
        return;

    // Play sound notification        
    m_pSound->play();
}

Note that m_pSound is now declared as a member variable of MainWindow.
