Subject Event listener problem
Date Wed, 11 Jan 2006 06:08:15 GMT
Hello All,
  I want to handle a "click" event in a SVG document.

My code looks like this

public class PositionNrSelect implements EventListener
    {
        public void handleEvent(Event evt) 
        {
            Element e=(Element)evt.getTarget();
            if(e.getFirstChild()!=null)
            {
                  // Do necessary processing....
            }
            
        }
    }


I am adding the EVent listener as follows

String parser = XMLResourceDescriptor.getXMLParserClassName();
                     SAXSVGDocumentFactory f = new SAXSVGDocumentFactory(parser);
                     svgDocument =  (SVGDocument) f.createDocument(svgFileSys.toURL().toString());
                     svgCanvas.setDocument(svgDocument);
Element elt2 = svgCanvas.getSVGDocument().getRootElement();
                     EventTarget t2 = (EventTarget)elt2;
                     t2.addEventListener("click",new PositionNrSelect(),true);

Problem I am facing is ,Whenever I click on a number which is shown on loaded SVG I am able
to enter into the evnt handling code that I have written , after this I am getting error Dailog
of following type.
----
SVG Error:
E:\Mahesh\projects\geproject\Valid-test-data\new-test-data\case1\F3.072.200--001TKGMUL_03\UT_1
(The system cannot find the file specified)
-----
If I click on "details"  button error shown is as folows

java.io.FileNotFoundException: E:\Mahesh\projects\geproject\Valid-test-data\new-test-data\case1\F3.072.200--001TKGMUL_03\UT_1

    at org.apache.batik.swing.svg.SVGDocumentLoader.run(Unknown Source)

After which click has no effects ,either I donmt get error nor I the control enters the Event
handling code.
What is the problem?
Is this possible fource to ignore the error dialog?

Please reply

Note:
  I am pasting that part of SVG on which I am clicking...

<g id="UT">
  <metadata id="CorelCorpID_2Corel-Layer"/>
  <g id="UT_1_REF">
   <polyline id="UT_1_REF_1" class="fil2 str2" points="203.483,72.9546 203.483,67.3247

   <line id="UT_1_REF_2" class="fil2 str2" x1="166.739" y1="105.01" x2="203.713" y2= "71.3094"

   <polyline id="UT_1_REF_3" class="fil2 str3" points="203.686,72.7773 203.686,67.5537

   <a xlink:href="UT_1">
    <rect class="fil4" x="205" y="68" width="1" height="3"/>
    <g transform="matrix(0.691005 0 0 1 108.866 -19.0694)">
     <text x="140.034" y="90.4591" id="UT_1_REF_4" class="fil5 fnt0">1</text>
    </g>
   </a>
  </g>
