Re: how to modify a svg displayed svgcanvas

[Steffen]

sorry, but i dont have any clue how to do this practically. may you please give some example code: i have something like this:            JSVGCanvas worldMap = new JSVGCanvas();         //get the XML Code from "world.svg"           String parser = XMLResourceDescriptor.getXMLParserClassName();           SAXSVGDocumentFactory f = new SAXSVGDocumentFactory(parser);           String uri = "http://www.nettrace.de/world.svg";           Document worldWithRectangle = f.createDocument(uri);                                      //create a new rectangle node           Element rectangle = world.createElementNS(uri, "rect");           rectangle.setAttributeNS(null, "x", "10");           rectangle.setAttributeNS(null, "y", "20");           rectangle.setAttributeNS(null, "width", "100");           rectangle.setAttributeNS(null, "height", "50");           rectangle.setAttributeNS(null, "style", "fill:red");        //add the rectangle to the xml of world.svg           worldWithRectangle.appendChild(rectangle);                    //show the 'new' SVGDocument           worldMap.setDocument(worldWithRectangle); but this brings the following exception:   [EMAIL PROTECTED] org.w3c.dom.DOMException: The current node (type: 9, name: #document) do not allow children of the given type (type: 1, name: rect)at org.apache.batik.dom.AbstractNode.createDOMException(Unknown Source) at org.apache.batik.dom.AbstractDocument.checkChildType(Unknown Source) at org.apache.batik.dom.AbstractParentNode.checkAndRemove(Unknown Source) at org.apache.batik.dom.AbstractParentNode.appendChild(Unknown Source) at AppletApplication.init(AppletApplication.java:151) at sun.applet.AppletPanel.run(Unknown Source) at java.lang.Thread.run(Unknown Source)
