Hi guys this is my first post in the forum.
I'm just started to use the batik framework.
I'm writing an applet to show a svg file. I use eclipse as IDE to develop
the applet an it works. It show me the svg file.
When i tried to do the same on an html page using the applet tag, the applet
doesn't show at all.
I've added an display message on start of the applet and i see it but the
svg file isn't show.
Can anyone help me?
the Source of the applet is the following:
public class SVGViewer extends JApplet {
JSVGCanvas svgCanvas;
Document document;
Window window;
public void init()
{
String svgName;
try
{
svgCanvas = new JSVGCanvas();
getContentPane().add(svgCanvas);
svgName = getParameter("svgName");
// Parse the barChart.svg file into a Document.
String parser = XMLResourceDescriptor.getXMLParserClassName();
//SAXSVGDocumentFactory f = new SAXSVGDocumentFactory(parser);
URL url = new URL(getCodeBase(), svgName);
svgCanvas.setURI(url.toString());
//document = f.createDocument(url.toString());
setBackground(Color.ORANGE);
}
catch (Exception e) {
// TODO: handle exception
}
}
public void start()
{
JOptionPane.showMessageDialog(this, "STart");
svgCanvas.setDocumentState(JSVGCanvas.ALWAYS_DYNAMIC);
//svgCanvas.setDocument(document);
//svgCanvas.setURI("a/846004349.image");
try
{
svgCanvas.addSVGLoadEventDispatcherListener
(new SVGLoadEventDispatcherAdapter() {
public void svgLoadEventDispatchStarted
(SVGLoadEventDispatcherEvent e) {
// At this time the document is available...
document = svgCanvas.getSVGDocument();
Element root = document.getDocumentElement();
int w =
(int)Double.parseDouble(root.getAttribute("width"));
int h =
(int)Double.parseDouble(root.getAttribute("height"));
setSize(w, h);
// ...and the window object too.
window =
svgCanvas.getUpdateManager().getScriptingEnvironment().createWindow();
//window.alert("INIt");
// Registers the listeners on the document
// just before the SVGLoad event is dispatched.
registerListeners();
// It is time to pack the frame.
}
});
}
catch (Exception e) {
// TODO: handle exception
}
//window =
svgCanvas.getUpdateManager().getScriptingEnvironment().createWindow();
}
public void stop()
{
svgCanvas.setDocument(null);
}
public void destroy()
{
svgCanvas.dispose();
}
public void registerListeners() {
