|
51 \brief The QVideoWidgetControl class provides a media control which |
|
52 implements a video widget. |
|
53 |
|
54 \ingroup multimedia-serv |
|
55 |
|
56 The videoWidget() property of QVideoWidgetControl provides a pointer to |
|
57 a video widget implemented by the control's media service. This widget |
|
58 is owned by the media service and so care should be taken not to delete it. |
|
59 |
|
60 \code |
|
61 QVideoWidgetControl *widgetControl = mediaService->control<QVideoWidgetControl *>(); |
|
62 |
|
63 layout->addWidget(widgetControl->widget()); |
|
64 \endcode |
|
65 |
|
66 QVideoWidgetControl is one of number of possible video output controls, |
|
67 in order to receive video it must be made the active video output |
|
68 control by setting the output property of QVideoOutputControl to \l {QVideoOutputControl::WidgetOutput}{WidgetOutput}. Consequently any |
|
69 QMediaService that implements QVideoWidgetControl must also implement |
|
70 QVideoOutputControl. |
|
71 |
|
72 The interface name of QVideoWidgetControl is \c com.nokia.Qt.QVideoWidgetControl/1.0 as |
|
73 defined in QVideoWidgetControl_iid. |
