Re: ScriptHandler: need example.

[Vincent Hardy <vi...@sun.com>]

Ludovic,

You are close to what you want. When you run your code, the circle comes 
out yellow right? It does in my environment. If it does not in yours, it 
may be because you are running an old version of Batik. You would need 
to switch to 1.5beta5 or, even better, the current CVS version.

However, to have an onclick handler, the code in the SVG file and in 
your Java file need to be modified.

SVG: No 'onclick' attribute

<?xml version="1.0" standalone="no"?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.0//EN" 
"http://www.w3.org/TR/2001/REC-SVG-20010904/DTD/svg10.dtd">
<svg xmlns="http://www.w3.org/2000/svg"
     xmlns:xlink="http://www.w3.org/1999/xlink">

   <script type="application/java-archive"
           xlink:href="SVGApplication.jar" />
   <circle id="myclic-circle" cx="25" cy="25" r="25" fill="red" />
</svg>

Handler:

import org.w3c.dom.*;
import org.w3c.dom.events.*;
import org.apache.batik.script.ScriptHandler;
import org.apache.batik.script.Window;

public class SVGApplication implements ScriptHandler, EventListener {
    private Document document;
   
    public void run (final Document document, final Window win) {
        this.document = document;
        EventTarget changecolor = 
(EventTarget)document.getElementById("myclic-circle");
        changecolor.addEventListener("click", this, false);
    }
   
    public void handleEvent(Event evt) {
        Element changecolor = document.getElementById("myclic-circle");
        changecolor.setAttributeNS(null, "fill", "#0F0");
    }
}

Vincent.
