59 \brief The QMediaControl class provides a base interface for media service controls.
60
61 Media controls provide an interface to individual features provided by a
62 media service. Most services implement a principal control which exposes
63 the core functionality of the service and a number of optional controls which
64 expose any additional functionality.
65
66 A pointer to a control implemented by a media service can be obtained using
67 the \l {QMediaService::requestControl()} member of QMediaService. If the
68 service doesn't implement a control it will instead return a null pointer.
69
70 \snippet multimedia-snippets/media.cpp Request control
71
72 Alternatively if the IId of the control has been declared using
73 Q_MEDIA_DECLARE_CONTROL the template version of
74 QMediaService::requestControl() can be used to request the service without
75 explicitly passing the IId or using qobject_cast().
76
77 \snippet multimedia-snippets/media.cpp Request control templated
78
79 Most application code will not interface directly with a media service's
80 controls, instead the QMediaObject which owns the service acts as an
81 intermediary between one or more controls and the application.

87 \macro Q_MEDIA_DECLARE_CONTROL(Class, IId)
88 \relates QMediaControl
89
90 The Q_MEDIA_DECLARE_CONTROL macro declares an \a IId for a \a Class that
91 inherits from QMediaControl.
92
93 Declaring an IId for a QMediaControl allows an instance of that control to
94 be requested from QMediaService::requestControl() without explicitly
95 passing the IId.
