Hi There,
I've been reading this thred with interest, because
I'm trying to accomplish something similar.
I'm using batik to generate SVG output for display in
a Java application. I'm putting text and lines (with
unique "id" attributes) in the SVG display, and I
want the java app to be notified when the mouse passes
over, or is clicked on, a text or line element.
You say:"The easiest thing to do is add a DOM 'click'
event listener on the root SVG element."
If by "root SVG Element" you mean the element you get
from:
DOMImplementation impl =
SVGDOMImplementation.getDOMImplementation();
this.svgDoc =
(SVGDocument)impl.createDocument(svgNS, "svg", null);
this.svgRoot = svgDoc.getDocumentElement();
Then I don't see how to add a listener to svgRoot, as
it doesn't have any addListener methods. Neither does
svgDoc.
However, the svgCanvas I get from
this.svgCanvas = new JSVGCanvas();
does have listener Methods. Is that where I should
register a listener? And if so, could you tell me
which listener, and how to find out the id of the
clicked element?
Where does the DOMEvent come from?
Thanks in advance for any advice you can give me. I'm
really stimied on this one.
Yours,
