Hi. This method is used to get the svgdocument:
public static SVGDocument textToSVGDocument(String xmlSvg) throws
Exception{
SAXSVGDocumentFactory ssdf = new
SAXSVGDocumentFactory(XMLResourceDescriptor.getXMLParserClassName());
return
(SVGDocument)ssdf.createDocument("http:\\\\idi.ntnu.no\\~fredrhag\\test.svg"
,new StringReader(xmlSvg));
}
The method returns a SVGDocument (the text is parsed and everything is
ok...). The uri input to the createDocument is chosen at "random" since the
document is created from a string which has no uri. Does it matter? What is
the uri used for?
It can matter, that is used as the 'base URL' for the document.
This is used when resolving external references (mostly images).
Neither (from code below) gvtBuildSucceded/Failed or Cancelled is called.
One of then should be called right?
Yes in all cases one of them must be called if gvtBuildStarted
is called. Is Build Started called?
Also have you "looked" at the Document you get back?
Sincerely, Fredrik

Hi Fredrik,

I tried posting this some days ago, but got no answer. I guess something
went wrong (had just registered for this mail-list), so I'm trying again.
I've successfully loaded and displayed a document by calling the
loadSVGDocument [1] with an uri. But if trying the setSVGDocument [2] with
a
SVGDocument instance, nothing happens at [3].
gvtBuildCompleted is never called when using the setSVGDocument... Any
ideas?
Unless you have any more information not really ;)
How are you creating the SVG Document? You might want to read
the thread about 'namespace woes'.
Sincerely, Fredrik
----CODE----
[1] svgCanvas.loadSVGDocument(someValidURI);
[2] svgCanvas.setSVGDocument(someSVGDocument);
[3] waitForGVTTreeBuilding();
private void waitForGVTTreeBuilding(){
GVTTreeBuilderAdapter gvtba = new GVTTreeBuilderAdapter() {
public void gvtBuildCompleted(GVTTreeBuilderEvent evt) {
synchronized(this){notify();}
}
public void gvtBuildFailed(GVTTreeBuilderEvent evt){
JOptionPane.showMessageDialog(gjf,"En feil skjedde under
lasting av svg. "+evt.toString(),"Feil under
lasting",JOptionPane.ERROR_MESSAGE);
}
public void gvtBuildCancelled(GVTTreeBuilderEvent evt){
JOptionPane.showMessageDialog(gjf,"En feil skjedde under
lasting av svg. "+evt.toString(),"Feil under
lasting",JOptionPane.ERROR_MESSAGE);
}
};
svgCanvas.addGVTTreeBuilderListener(gvtba);
try{synchronized(gvtba){gvtba.wait(0);}}catch(Exception
e){e.printStackTrace();}
}
