<div class="descr">
<h2 id="details">Detailed Description</h2>
<p>The <a href="qgraphicssvgitem.html">QGraphicsSvgItem</a> class is a <a href="../qtwidgets/qgraphicsitem.html">QGraphicsItem</a> that can be used to render the contents of SVG files.</p>
<p><a href="qgraphicssvgitem.html">QGraphicsSvgItem</a> provides a way of rendering SVG files onto <a href="../qtwidgets/qgraphicsview.html">QGraphicsView</a>. <a href="qgraphicssvgitem.html">QGraphicsSvgItem</a> can be created by passing the SVG file to be rendered to its constructor or by explicit setting a shared <a href="qsvgrenderer.html">QSvgRenderer</a> on it.</p>
<p>Note that setting <a href="qsvgrenderer.html">QSvgRenderer</a> on a <a href="qgraphicssvgitem.html">QGraphicsSvgItem</a> doesn't make the item take ownership of the renderer, therefore if using <a href="qgraphicssvgitem.html#setSharedRenderer">setSharedRenderer</a>() method one has to make sure that the lifetime of the <a href="qsvgrenderer.html">QSvgRenderer</a> object will be at least as long as that of the <a href="qgraphicssvgitem.html">QGraphicsSvgItem</a>.</p>
<p><a href="qgraphicssvgitem.html">QGraphicsSvgItem</a> provides a way of rendering only parts of the SVG files via the <a href="qgraphicssvgitem.html#elementId-prop">setElementId</a>. If <a href="qgraphicssvgitem.html#elementId-prop">setElementId</a>() method is called, only the SVG element (and its children) with the passed id will be renderer. This provides a convenient way of selectively rendering large SVG files that contain a number of discrete elements. For example the following code renders only jokers from a SVG file containing a whole card deck:</p>
<pre class="cpp"><span class="type"><a href="qsvgrenderer.html">QSvgRenderer</a></span> <span class="operator">*</span>renderer <span class="operator">=</span> <span class="keyword">new</span> <span class="type"><a href="qsvgrenderer.html">QSvgRenderer</a></span>(QLatin1String(<span class="string">&quot;SvgCardDeck.svg&quot;</span>));
<span class="type"><a href="qgraphicssvgitem.html#QGraphicsSvgItem">QGraphicsSvgItem</a></span> <span class="operator">*</span>black <span class="operator">=</span> <span class="keyword">new</span> <span class="type"><a href="qgraphicssvgitem.html#QGraphicsSvgItem">QGraphicsSvgItem</a></span>();
<span class="type"><a href="qgraphicssvgitem.html#QGraphicsSvgItem">QGraphicsSvgItem</a></span> <span class="operator">*</span>red   <span class="operator">=</span> <span class="keyword">new</span> <span class="type"><a href="qgraphicssvgitem.html#QGraphicsSvgItem">QGraphicsSvgItem</a></span>();

black<span class="operator">-</span><span class="operator">&gt;</span><a href="qgraphicssvgitem.html#setSharedRenderer">setSharedRenderer</a>(renderer);
black<span class="operator">-</span><span class="operator">&gt;</span><a href="qgraphicssvgitem.html#elementId-prop">setElementId</a>(QLatin1String(<span class="string">&quot;black_joker&quot;</span>));

red<span class="operator">-</span><span class="operator">&gt;</span><a href="qgraphicssvgitem.html#setSharedRenderer">setSharedRenderer</a>(renderer);
red<span class="operator">-</span><span class="operator">&gt;</span><a href="qgraphicssvgitem.html#elementId-prop">setElementId</a>(QLatin1String(<span class="string">&quot;red_joker&quot;</span>));</pre>
<p>Size of the item can be set via the <a href="../qtcore/qrectf.html#setSize">setSize()</a> method of the <a href="qgraphicssvgitem.html#boundingRect">bounding rectangle</a> or via direct manipulation of the items transformation matrix.</p>
<p>By default the SVG rendering is cached using <a href="../qtwidgets/qgraphicsitem.html#CacheMode-enum">QGraphicsItem::DeviceCoordinateCache</a> mode to speedup the display of items. Caching can be disabled by passing <a href="../qtwidgets/qgraphicsitem.html#CacheMode-enum">QGraphicsItem::NoCache</a> to the <a href="../qtwidgets/qgraphicsitem.html#setCacheMode">QGraphicsItem::setCacheMode</a>() method.</p>
