<div class="descr">
<h2 id="details">Detailed Description</h2>
<p>The <a href="qsvgrenderer.html">QSvgRenderer</a> class is used to draw the contents of SVG files onto paint devices.</p>
<p>Using <a href="qsvgrenderer.html">QSvgRenderer</a>, Scalable Vector Graphics (SVG) can be rendered onto any <a href="../qtgui/qpaintdevice.html">QPaintDevice</a> subclass, including <a href="../qtwidgets/qwidget.html">QWidget</a>, <a href="../qtgui/qimage.html">QImage</a>, and QGLWidget.</p>
<p><a href="qsvgrenderer.html">QSvgRenderer</a> provides an API that supports basic features of SVG rendering, such as loading and rendering of static drawings, and more interactive features like animation. Since the rendering is performed using <a href="../qtgui/qpainter.html">QPainter</a>, SVG drawings can be rendered on any subclass of <a href="../qtgui/qpaintdevice.html">QPaintDevice</a>.</p>
<p>SVG drawings are either loaded when an <a href="qsvgrenderer.html">QSvgRenderer</a> is constructed, or loaded later using the <a href="qsvgrenderer.html#load">load</a>() functions. Data is either supplied directly as serialized XML, or indirectly using a file name. If a valid file has been loaded, either when the renderer is constructed or at some later time, <a href="qsvgrenderer.html#isValid">isValid</a>() returns true; otherwise it returns false. <a href="qsvgrenderer.html">QSvgRenderer</a> provides the <a href="qsvgrenderer.html#render">render</a>() slot to render the current document, or the current frame of an animated document, using a given painter.</p>
<p>The <a href="qsvgrenderer.html#defaultSize">defaultSize</a>() function provides information about the amount of space that is required to render the currently loaded SVG file. This is useful for paint devices, such as <a href="../qtwidgets/qwidget.html">QWidget</a>, that often need to supply a size hint to their parent layout. The default size of a drawing may differ from its visible area, found using the <a href="qsvgrenderer.html#viewBox-prop">viewBox</a> property.</p>
<p>Animated SVG drawings are supported, and can be controlled with a simple collection of functions and properties:</p>
<ul>
<li>The <a href="qsvgrenderer.html#animated">animated</a>() function indicates whether a drawing contains animation information.</li>
<li>The <a href="qsvgrenderer.html#framesPerSecond-prop">framesPerSecond</a> property contains the rate at which the animation plays.</li>
</ul>
<p>Finally, the <a href="qsvgrenderer.html">QSvgRenderer</a> class provides the <a href="qsvgrenderer.html#repaintNeeded">repaintNeeded</a>() signal which is emitted whenever the rendering of the document needs to be updated.</p>
