\class QMediaControl
\ingroup multimedia
\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()
