<p>The <a href="qvideowidget.html">QVideoWidget</a> class provides a widget which presents video produced by a media object.</p>
<p>Attaching a <a href="qvideowidget.html">QVideoWidget</a> to a <a href="qmediaobject.html">QMediaObject</a> allows it to display the video or image output of that media object. A <a href="qvideowidget.html">QVideoWidget</a> is attached to media object by passing a pointer to the <a href="qmediaobject.html">QMediaObject</a> in its constructor, and detached by destroying the <a href="qvideowidget.html">QVideoWidget</a>.</p>
