Detailed Description

The QSoundControl class extends the functionality of the QSound class.

The QSoundControl class can be used to control the volume, priority and provide the status for a QSound object.

Construct a QSoundControl object with an exising QSound object.

    QSoundControl *control = new QSoundControl( new QSound( "test.wav" ) );

The control may now be used to alter the behavior of the sound object.

    control->setVolume( 50 );
    control->setPriority( QSoundControl::RingTone );

In additon the control may be used to listen for when the sound object finishes playback.

    connect( control, SIGNAL(done()), this, SLOT(doSomething()) );

The control object does not take owenership of the sound object. Care must be taken to ensure the sound object remains valid for the life of the control object.

    delete control->sound();
    delete control;
