To include the definitions of the module's classes, use the following directive:</p> <pre class="cpp"> <span class="preprocessor">#include <QtSvg></span> </pre> <p>To link against the module, add this line to your qmake <code>.pro</code> file:</p> <pre class="cpp"> QT += svg </pre> <a name="rendering-svg-files"></a> <h2 id="rendering-svg-files">Rendering SVG Files</h2> <p>Scalable Vector Graphics (SVG) is a language for describing two-dimensional graphics and graphical applications in XML. SVG 1.1 is a W3C Recommendation and forms the core of the current SVG developments in Qt. SVG 1.2 is the specification currently being developed by the SVG Working Group, and it is <a href="http://www.w3.org/TR/SVG12/">available in draft form</a>. The Mobile SVG Profiles (SVG Basic and SVG Tiny) are aimed at resource-limited devices and are part of the 3GPP platform for third generation mobile phones. You can read more about SVG at About SVG.</p> <p>Qt supports the static features of <a href="http://www.w3.org/TR/SVGMobile12">SVG 1.2 Tiny</a>. ECMA scripts and DOM manipulation are currently not supported.</p> <p>SVG drawings can be rendered onto any QPaintDevice subclass. This approach gives developers the flexibility to experiment, in order to find the best solution for each application.</p> <p>The easiest way to render SVG files is to construct a <a href="qsvgwidget.html">QSvgWidget</a> and load an SVG file using one of the <a href="qsvgwidget.html#load">QSvgWidget::load</a>() functions.</p> <p><a href="qsvgrenderer.html">QSvgRenderer</a> is the class responsible for rendering SVG files for <a href="qsvgwidget.html">QSvgWidget</a>, and it can be used directly to provide SVG support for custom widgets. To load an SVG file, construct a <a href="qsvgrenderer.html">QSvgRenderer</a> with a file name or the contents of a file, or call <a href="qsvgrenderer.html#load">QSvgRenderer::load</a>() on an existing renderer. If the SVG file has been loaded successfully the <a href="qsvgrenderer.html#isValid">QSvgRenderer::isValid</a>() will return true.</p> <p>Once you have loaded the SVG file successfully, you can render it with the <a href="qsvgrenderer.html#render">QSvgRenderer::render</a>() function. Note that this scheme allows you to render SVG files on all paint devices supported by Qt, including QWidget, QGLWidget, and QImage. See the SVG Viewer example for more details.</p> </div> <!-- @@@svgrendering.html --> </div> </div> </div> </div> </div> <div class="footer"> <p> <acronym title="Copyright">©</acronym> 2019 The Qt Company Ltd.
