<p>The QSvgWidget class provides a widget that is used to display the contents of Scalable Vector Graphics (SVG) files.</p> <p>This class enables developers to display SVG drawings alongside standard widgets, and is used in much the same way as <a href="qlabel.html">QLabel</a> is used for displaying text and bitmap images.</p> <p>Since QSvgWidget is a subclass of <a href="qwidget.html">QWidget</a>, SVG drawings are rendered using the properties of the display. More control can be exercised over the rendering process with the <a href="qsvgrenderer.html">QSvgRenderer</a> class, as this can be used to paint onto other paint devices, such as <a href="qimage.html">QImage</a> and <a href="qglwidget.html">QGLWidget</a>. The renderer used by the widget can be obtained with the <a href="qsvgwidget.html#renderer">renderer</a>() function.</p> <p>Each QSvgWidget can be constructed with the file name of a SVG file, or they can be constructed without a specific file to render and one can be supplied later. The <a href="qsvgwidget.html#load">load</a>() functions provide two different ways to load an SVG file: they accept either the file name of an SVG file or a <a href="qbytearray.html">QByteArray</a> containing the serialized XML representation of an SVG file.</p> <p>By default, the widget provides a size hint to reflect the size of the drawing that it displays. If no data has been loaded, the widget provides the default <a href="qwidget.html">QWidget</a> size hint. Subclass this class and reimplement <a href="qsvgwidget.html#sizeHint">sizeHint</a>() if you need to customize this behavior.</p> </div> <p><b>See also </b><a href="qsvgrenderer.html">QSvgRenderer</a>, <a href="qtsvg.html">QtSvg Module</a>, and <a href="qpicture.html">QPicture</a>.</p> <!-- @@@QSvgWidget --> <div class="func"> <h2>Member Function Documentation</h2> <!-- $$$QSvgWidget[overload1]$$$QSvgWidgetQWidget* --> <h3 class="fn"><a name="QSvgWidget"></a>QSvgWidget::<span class="name">QSvgWidget</span> ( <span class="type"><a href="qwidget.html">QWidget</a></span> * <i>parent</i> = 0 )</h3> <p>Constructs a new SVG display widget with the given <i>parent</i>.</p> <!-- @@@QSvgWidget --> <!-- $$$QSvgWidget$$$QSvgWidgetconstQString&QWidget* --> <h3 class="fn"><a name="QSvgWidget-2"></a>QSvgWidget::<span class="name">QSvgWidget</span> ( const <span class="type"><a href="qstring.html">QString</a></span> & <i>file</i>, <span class="type"><a href="qwidget.html">QWidget</a></span> * <i>parent</i> = 0 )</h3> <p>Constructs a new SVG display widget with the given <i>parent</i> and loads the contents of the specified <i>file</i>.</p> <!-- @@@QSvgWidget --> <!-- $$$~QSvgWidget[overload1]$$$~QSvgWidget --> <h3 class="fn"><a name="dtor.QSvgWidget"></a>QSvgWidget::<span class="name">~QSvgWidget</span> ()</h3> <p>Destroys the widget.</p> <!-- @@@~QSvgWidget --> <!-- $$$load[overload1]$$$loadconstQString& --> <h3 class="fn"><a name="load"></a><span class="type">void</span> QSvgWidget::<span class="name">load</span> ( const <span class="type"><a href="qstring.html">QString</a></span> & <i>file</i> )<tt> [slot]</tt></h3> <p>Loads the contents of the specified SVG <i>file</i> and updates the widget.</p> <!-- @@@load --> <!-- $$$load$$$loadconstQByteArray& --> <h3 class="fn"><a name="load-2"></a><span class="type">void</span> QSvgWidget::<span class="name">load</span> ( const <span class="type"><a href="qbytearray.html">QByteArray</a></span> & <i>contents</i> )<tt> [slot]</tt></h3> <p>Loads the specified SVG format <i>contents</i> and updates the widget.</p> <!-- @@@load --> <!-- $$$paintEvent[overload1]$$$paintEventQPaintEvent* --> <h3 class="fn"><a name="paintEvent"></a><span class="type">void</span> QSvgWidget::<span class="name">paintEvent</span> ( <span class="type"><a href="qpaintevent.html">QPaintEvent</a></span> * <i>event</i> )<tt> [virtual protected]</tt></h3> <p>Reimplemented from <a href="qwidget.html#paintEvent">QWidget::paintEvent</a>().</p> <!-- @@@paintEvent --> <!-- $$$renderer[overload1]$$$renderer --> <h3 class="fn"><a name="renderer"></a><span class="type"><a href="qsvgrenderer.html">QSvgRenderer</a></span> * QSvgWidget::<span class="name">renderer</span> () const</h3> <p>Returns the renderer used to display the contents of the widget.</p> <!-- @@@renderer --> <!-- $$$sizeHint[overload1]$$$sizeHint --> <h3 class="fn"><a name="sizeHint"></a><span class="type"><a href="qsize.html">QSize</a></span> QSvgWidget::<span class="name">sizeHint</span> () const<tt> [virtual]</tt></h3> <p>Reimplemented from <a href="qwidget.html#sizeHint-prop">QWidget::sizeHint</a>().</p> <!-- @@@sizeHint --> </div> </div> </div> </div> <div class="ft"> <span></span> </div> </div> <div class="footer"> <p> <acronym title="Copyright">©</acronym> 2013 Digia Plc and/or its subsidiaries.
