I'm new to using batik, and I want to turn all text elements in an SVGDocument into links which pass the text to a callback. Can you point me to an example of something similar? I'm finding the text elements like this:
There is no need to
SVGDocument doc = ... Element svgRoot = doc.getDocumentElement(); NodeList labels = svgRoot.getElementsByTagNameNS("*", "text"); Node n; for(int i=0;i<labels.getLength();i++) { n = labels.item(i); log.info("A label:"+n.getFirstChild().getNodeValue());
EventListener l = new EventListener { public void handleEvent(Event evt) { // you can try to use the current n element here, that // means you need to make it final and build one listener // for each element or use evt.getTarget() to get the // element and use only one listener instance per document } } n.addEventListener("click", l, false)
//presumably, replace n with a link element that contains n? }
You can use too event bubbling on the addEventListener and attach only one listener on the document root and check the element type you are getting, instead of attaching a listener to each element, the advantage of this method is that it work for all text elements you add later without need to add a listener to them
