onclick event
I tried to render a simple svg file with an onclick event (a circle which
size is changed when clicked, found on
http://www.w3.org/TR/SVG/images/script/script01.svg) inside a JSVGCanvas
but the click does not seem to be interpreted (the size of the circle
remains the same).
Is there somtehing special I need to tell my JSVGCanvas?
I'd like as well to be informed when this event is triggered in my Java
code. Is there a listener for that purpose?
I tried to find a solution by myself but as the last javadoc has not been
released, there are some differences with the source that make guessing
painful. As far as I could guess, it seems that this can be done with
UserAgent but I can't figure out how to create one in order to give it to
the JSVGCanvas constructor.
Philippe.

Philippe,
Did you check that your class is in your classpath when your run
Batik?

Thanks for the advice.
I looked at samples\batikMusic.svg and found this is exactly what I want to
do : calling some java code from javascript.
Unfortunately I can't figure out how to call one of my classes, I always
get error messages like "scripting error : myclass is not defined".
Even if I use importPackage(myPackage), any call to myClass will fail but
it seems to work fine for standard java package. Is there a specific
configuration to allow proprietary package to be accessed in EcmaScript?
Thanks,
Philippe

Philippe,
You should be able to position event listeners in your SVG source and
you can look at the samples\batikMusic.svg example for an example.
Positioning event handlers on the GVT tree is not recommended, even
though it is possible, as you discovered. It is not recommended because
this ties what you are doing with your SVG to the viewer you are using
and, as much as I love Batik, it is not a good idea to tie you SVG
code to that particular implementation.

OK, I finally managed to be warned when an onclick event appear using a
GraphicsNodeMouseListener.
This listener is added on the GraphicsNode corresponding to the SVG
Element, the GraphicsNode being retrieved using the BridgeContext. That was
hard to guess but it seems to be the right way. Please tell me if there is
a simpler way.
I'm style worried about the circle in my SVG file example which is not
updated when it is clicked. Is interactive feature not yet supported by
JSVGCanvas?
Sorry to bother you with all this questions but I'm doing some tests on
Batik in order to decide if it is mature enough to use it in the next
release of our Java based application (see ViewletBuilder at
www.qarbon.com) to do some SVG stuff. So any help would be greatly appreciated.
