Member Function Documentation

   void QwtPlotSvgItem::draw (QPainter * painter, const QwtScaleMap & xMap, const QwtScaleMap &
       yMap, const QRectF & canvasRect) const [virtual]
       Draw the SVG item

       Parameters:
           painter Painter
           xMap X-Scale Map
           yMap Y-Scale Map
           canvasRect Contents rect of the plot canvas

       Implements QwtPlotItem.

   bool QwtPlotSvgItem::loadData (const QRectF & rect, const QByteArray & data)
       Load SVG data

       Parameters:
           rect Bounding rectangle
           data in SVG format

       Returns:
           true, if the SVG data could be loaded

   bool QwtPlotSvgItem::loadFile (const QRectF & rect, const QString & fileName)
       Load a SVG file

       Parameters:
           rect Bounding rectangle
           fileName SVG file name

       Returns:
           true, if the SVG file could be loaded

   void QwtPlotSvgItem::render (QPainter * painter, const QRectF & viewBox, const QRectF & rect)
       const [protected]

   int QwtPlotSvgItem::rtti () const [virtual]
       Returns:
           QwtPlotItem::Rtti_PlotSVG

       Reimplemented from QwtPlotItem.

   QRectF QwtPlotSvgItem::viewBox (const QRectF & rect) const [protected]
       Calculate the view box from rect and boundingRect().

       Parameters:
           rect Rectangle in scale coordinates

       Returns:
           View box, see QSvgRenderer::viewBox()
