- \class QVideoWidget
- \preliminary
- \since 4.7
- \brief The QVideoWidget class provides a widget which presents video
- produced by a media object.
- \ingroup multimedia
-
- Attaching a QVideoWidget to a QMediaObject allows it to display the
- video or image output of that media object. A QVideoWidget is attached
- to media object by passing a pointer to the QMediaObject in its
- constructor, and detached by destroying the QVideoWidget.
-
- \code
- player = new QMediaPlayer;
-
- widget = new QVideoWidget(player);
- widget->show();
-
- player->setMedia(QUrl("http://example.com/movie.mp4"));
- player->play();
- \endcode
-
- \bold {Note}: Only a single display output can be attached to a media
- object at one time.
