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 modify the document
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
Thanks in advance,
Jim
