<h2>Detailed Description</h2>
<p>The QVideoWidgetControl class provides a media control which implements a video widget.</p>
<p>The <a href="qvideowidgetcontrol.html#videoWidget">videoWidget</a>() 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.</p>
<pre class="cpp"></pre>
<p>QVideoWidgetControl is one of number of possible video output controls.</p>
<p>The interface name of QVideoWidgetControl is <tt>org.qt-project.qt.videowidgetcontrol/5.0</tt> as defined in <a href="qvideowidgetcontrol.html#QVideoWidgetControl_iid">QVideoWidgetControl_iid</a>.</p>
