+ \class QGraphicsSvgItem
+ \ingroup multimedia
+ \ingroup graphicsview-api
+ \brief The QGraphicsSvgItem class is a QGraphicsItem that can be used to render
+ the contents of SVG files.
+
+ \since 4.2
+
+ QGraphicsSvgItem provides a way of rendering SVG files onto QGraphicsView.
+ QGraphicsSvgItem can be created by passing the SVG file to be rendered to
+ its constructor or by explicit setting a shared QSvgRenderer on it.
+
+ Note that setting QSvgRenderer on a QGraphicsSvgItem doesn't make the item take
+ ownership of the renderer, therefore if using setSharedRenderer() method one has
+ to make sure that the lifetime of the QSvgRenderer object will be at least as long
+ as that of the QGraphicsSvgItem.
+
+ QGraphicsSvgItem provides a way of rendering only parts of the SVG files via
+ the setElementId. If setElementId() 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:
+
+ \snippet doc/src/snippets/code/src_svg_qgraphicssvgitem.cpp 0
+
+ Size of the item can be set via the setSize() method or via
+ direct manipulation of the items transformation matrix.
+
+ By default the SVG rendering is cached using QGraphicsItem::DeviceCoordinateCache
+ mode to speedup the display of items. Caching can be disabled by passing
+ QGraphicsItem::NoCache to the QGraphicsItem::setCacheMode() method.

+ \class QSvgRenderer
+ \ingroup multimedia
+
+ \brief The QSvgRenderer class is used to draw the contents of SVG files onto paint devices.
+ \since 4.1
+ \reentrant
+
+ Using QSvgRenderer, Scalable Vector Graphics (SVG) can be rendered onto any QPaintDevice
+ subclass, including QWidget, QImage, and QGLWidget.
+
+ QSvgRenderer 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 QPainter, SVG drawings can be rendered on any subclass of
+ QPaintDevice.
+
+ SVG drawings are either loaded when an QSvgRenderer is constructed, or loaded later
+ using the load() 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, isValid() returns true; otherwise it returns false.
+ QSvgRenderer provides the render() slot to render the current document, or the current
+ frame of an animated document, using a given painter.
+
+ The defaultSize() 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 QWidget,
+ 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 \l viewBox
+ property.
+
+ Animated SVG drawings are supported, and can be controlled with a simple collection of
+ functions and properties:
+
+ \list
+ \o The animated() function indicates whether a drawing contains animation information.
+ \omit
+ \o The animationDuration() function provides the duration in milliseconds of the
+ animation, without taking any looping into account.
+ \o The \l currentFrame property contains the current frame of the animation.
+ \endomit
+ \o The \l framesPerSecond property contains the rate at which the animation plays.
+ \endlist
+
+ Finally, the QSvgRenderer class provides the repaintNeeded() signal which is emitted
+ whenever the rendering of the document needs to be updated.

+ \class QSvgWidget
+ \ingroup multimedia
+
+ \brief The QSvgWidget class provides a widget that is used to display the contents of
+ Scalable Vector Graphics (SVG) files.
+ \since 4.1
+
+ This class enables developers to display SVG drawings alongside standard widgets, and
+ is used in much the same way as QLabel is used for displaying text and bitmap images.
+
+ Since QSvgWidget is a subclass of QWidget, SVG drawings are rendered using the properties
+ of the display. More control can be exercised over the rendering process with the
+ QSvgRenderer class, as this can be used to paint onto other paint devices, such as QImage
+ and QGLWidget. The renderer used by the widget can be obtained with the renderer()
+ function.
+
+ 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 load()
+ functions provide two different ways to load an SVG file: they accept either the file name
+ of an SVG file or a QByteArray containing the serialized XML representation of an SVG file.
+
+ 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 QWidget size hint.
+ Subclass this class and reimplement sizeHint() if you need to customize this behavior.
