Detailed Description

The QVideoWidgetControl class provides a media control which implements a video widget.

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.

 QVideoWidgetControl *widgetControl = mediaService->requestControl<QVideoWidgetControl *>();
 layout->addWidget(widgetControl->videoWidget());

QVideoWidgetControl is one of number of possible video output controls.

The interface name of QVideoWidgetControl is com.nokia.Qt.QVideoWidgetControl/1.0 as defined in QVideoWidgetControl_iid.

See also QMediaService::requestControl() and QVideoWidget.
