wow, thanks for your swift reply, Thomas.
I read your pdf presentation (I can tell I'll be
referring to that document quite a bit in the future,
thank you!), particularly the part with the code
snippet:
document = canvas.getSVGDocument();
elem = document.getElementById("foo");
elem.addEventListener([event-type],[listener],[use-capture]);
That makes sense to me, but my difficulty is that elem
doesn't seem to have a method named addEventListener.
The interface for org.w3c.dom.Element doesn't describe
any such method, and I get compile errors saying
there's no such method.
am I using the wrong version of something?
yours,
Don
