QMediaContentContext Class Reference
[QtMediaModule]

Player Objects

By convention player objects are defined by a setMediaContent() slot in the class declaration. The following declaration outlines a simple player object class.

    class PlayerObject : public QObject
    {
        Q_OBJECT
    public:
        PlayerObject( QObject* parent = 0 );

    public slots:
        void setMediaContent( QMediaContent* content );
    };

After creating a context add related player objects to the context. When setMediaContent() is called the context will also call setMediaContent() for all player objects added to the context.

    PlayerObject *a = new PlayerObject( this );
    PlayerObject *b = new PlayerObject( this );

    QMediaContentContext *context = new QMediaContentContext( this );
    context->addObject( a );
    context->addObject( b );

This way all player objects added to the context will always be working with the same media content object.

QMediaContentContext is a player object.
