The QGraphicsSvgItem class is a QGraphicsItem that can be used to render the contents of SVG files.
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:
Size of the item can be set via the setSize() method of the bounding rectangle 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.

| void QGraphicsSvgItem::setCachingEnabled | ( | bool | caching | ) |
Use QGraphicsItem::setCacheMode() instead.
Passing true to this function is equivalent to QGraphicsItem::setCacheMode(QGraphicsItem::DeviceCoordinateCache).
Definition at line 385 of file qgraphicssvgitem.cpp.
| void QGraphicsSvgItem::setElementId | ( | const QString & | id | ) |
Sets the XML ID of the element to id.
Definition at line 336 of file qgraphicssvgitem.cpp.
| void QGraphicsSvgItem::setMaximumCacheSize | ( | const QSize & | size | ) |
Sets the maximum device coordinate cache size of the item to size.
If the item is cached using QGraphicsItem::DeviceCoordinateCache mode, caching is bypassed if the extension of the item in device coordinates is larger than size.
The cache corresponds to the QPixmap which is used to cache the results of the rendering. Use QPixmapCache::setCacheLimit() to set limitations on the whole cache and use setMaximumCacheSize() when setting cache size for individual items.
Definition at line 299 of file qgraphicssvgitem.cpp.
| void QGraphicsSvgItem::setSharedRenderer | ( | QSvgRenderer * | renderer | ) |
Sets renderer to be a shared QSvgRenderer on the item.
By using this method one can share the same QSvgRenderer on a number of items. This means that the SVG file will be parsed only once. QSvgRenderer passed to this method has to exist for as long as this item is used.

This property holds the maximum size of the device coordinate cache for this item.
Returns the current maximum size of the device coordinate cache for this item.
If the item is cached using QGraphicsItem::DeviceCoordinateCache mode, caching is bypassed if the extension of the item in device coordinates is larger than the maximum size.
The default maximum cache size is 1024x768. QPixmapCache::cacheLimit() gives the cumulative bounds of the whole cache, whereas maximumCacheSize() refers to a maximum cache size for this particular item.
