I have been reading the mailing lists and collected
some code from the mailing list, and have a question:
Below you will find some code that will write the
id of the clicked element. From what I understand there should not be nessecary
to add a event listener for each element, since the mouse-event are propagating
through the element tree if one element is clicked. The code below shows only
the body-element, not all the other element. How is it possible to get the
element that really was clicked on?
//called when a
svg-document is loaded
private void
captureDOMEvent()
{ String svgid=svgCanvas.getSVGDocument().getRootElement().getId(); EventTarget t = (EventTarget)(svgCanvas.getSVGDocument().getElementById(svgid)); EventListener OnClickAction(svgCanvas); t.addEventListener("click", onClick, false); } import org.w3c.dom.Element; import org.w3c.dom.events.Event; import org.w3c.dom.events.EventListener; import org.apache.batik.swing.JSVGCanvas; public class OnClickAction implements EventListener, Runnable { Event evt; JSVGCanvas svgCanvas; public OnClickAction(JSVGCanvas svgCanvas) { this.svgCanvas=svgCanvas; } public void handleEvent(Event evt) { this.evt = evt; if (Thread.currentThread() == svgCanvas.getUpdateManager().getUpdateRunnableQueue().getThread()){ Element elt = (Element)(evt.getCurrentTarget()); if (elt != null) { String svgid = elt.getAttribute("id"); System.out.println("ID: "+svgid); } } else { try { svgCanvas.getUpdateManager(). getUpdateRunnableQueue().invokeLater (this); } catch (Exception e) { e.printStackTrace(); } } } public void run() { handleEvent(evt); } } Thanks Torstein
