\class QVideoWidgetControl
\preliminary
\since 4.7
\brief The QVideoWidgetControl class provides a media control which
implements a video widget.
\ingroup multimedia-serv
The videoWidget() property of QVideoWidgetControl provides a pointer to
a video widget implemented by the control's media service. This widget
is owned by the media service and so care should be taken not to delete it.
\code
QVideoWidgetControl *widgetControl = mediaService->control<QVideoWidgetControl *>();
layout->addWidget(widgetControl->widget());
\endcode
QVideoWidgetControl is one of number of possible video output controls,
in order to receive video it must be made the active video output
control by setting the output property of QVideoOutputControl to \l {QVideoOutputControl::WidgetOutput}{WidgetOutput}. Consequently any
QMediaService that implements QVideoWidgetControl must also implement
QVideoOutputControl.
The interface name of QVideoWidgetControl is \c com.nokia.Qt.QVideoWidgetControl/1.0 as
defined in QVideoWidgetControl_iid.
