    \preliminary

    \brief The QMediaControl class provides a base interface for media service controls.

    Media controls provide an interface to individual features provided by a

    media service.  Most services implement a principal control which exposes

    the core functionality of the service and a number optional controls which

    expose any additional functionality.

    A pointer to a control implemented by a media service can be obtained using

    the \l {QMediaService::requestControl()} member of QMediaService.  If the

    service doesn't implement a control it will instead return a null pointer.

    \code

    QMediaPlayerControl *control = qobject_cast<QMediaPlayerControl *>(

            service->requestControl("com.nokia.Qt.QMediaPlayerControl/1.0"));

    \endcode

    Alternatively if the IId of the control has been declared using

    Q_MEDIA_DECLARE_CONTROL the template version of

    QMediaService::requestControl() can be used to request the service without

    explicitly passing the IId.

    \code

    QMediaPlayerControl *control = service->requestControl<QMediaPlayerControl *>();

    \endcode

    Most application code will not interface directly with a media service's

    controls, instead the QMediaObject which owns the service acts as an

    intermediary between one or more controls and the application.

/*!

    \macro Q_MEDIA_DECLARE_CONTROL(Class, IId)

    \relates QMediaControl

    The Q_MEDIA_DECLARE_CONTROL macro declares an \a IId for a \a Class that

    inherits from QMediaControl.

    Declaring an IId for a QMediaControl allows an instance of that control to

    be requested from QMediaService::requestControl() without explicitly

    passing the IId.

    \code

    QMediaPlayerControl *control = service->control<QMediaPlayerControl *>();

    \endcode

    \sa QMediaService::requestControl()
