<div class="descr">
<h2>Detailed Description</h2>
<p>The QMediaImageViewer class provides a means of viewing image media.</p>
<p>QMediaImageViewer is used together with a media display object such as <a href="qvideowidget.html">QVideoWidget</a> to present an image. A display object is attached to the image viewer by means of the bind function.</p>
<pre class="cpp"> viewer <span class="operator">=</span> <span class="keyword">new</span> <span class="type">QMediaImageViewer</span>(<span class="keyword">this</span>);

 videoWidget <span class="operator">=</span> <span class="keyword">new</span> <span class="type"><a href="qvideowidget.html">QVideoWidget</a></span>;
 viewer<span class="operator">-</span><span class="operator">&gt;</span>bind(videoWidget);
 videoWidget<span class="operator">-</span><span class="operator">&gt;</span>show();</pre>
<p>QMediaImageViewer can be paired with a <a href="qmediaplaylist.html">QMediaPlaylist</a> to create a slide show of images. Constructing a <a href="qmediaplaylist.html">QMediaPlaylist</a> with a pointer to an instance of QMediaImageViewer will attach it to the image viewer; changing the playlist's selection will then change the media displayed by the image viewer. With a playlist attached QMediaImageViewer's <a href="qmediaimageviewer.html#play">play</a>(), <a href="qmediaimageviewer.html#pause">pause</a>(), and <a href="qmediaimageviewer.html#stop">stop</a>() slots can be control the progression of the playlist. The <a href="qmediaimageviewer.html#timeout-prop">timeout</a> property determines how long an image is displayed for before progressing to the next in the playlist, and the <a href="qmediaimageviewer.html#elapsedTime-prop">elapsedTime</a> property holds how the duration the current image has been displayed for.</p>
<pre class="cpp"> playlist <span class="operator">=</span> <span class="keyword">new</span> <span class="type"><a href="qmediaplaylist.html">QMediaPlaylist</a></span>(<span class="keyword">this</span>);
 playlist<span class="operator">-</span><span class="operator">&gt;</span>setPlaybackMode(<span class="type"><a href="qmediaplaylist.html">QMediaPlaylist</a></span><span class="operator">::</span>Loop);
 playlist<span class="operator">-</span><span class="operator">&gt;</span>addMedia(image1);
 playlist<span class="operator">-</span><span class="operator">&gt;</span>addMedia(image2);
 playlist<span class="operator">-</span><span class="operator">&gt;</span>addMedia(image3);

 viewer<span class="operator">-</span><span class="operator">&gt;</span>setPlaylist(playlist);
 viewer<span class="operator">-</span><span class="operator">&gt;</span>setTimeout(<span class="number">5000</span>);
