I need to add some script for canvas. I did it like following, but it doesn't work.
code in customize LCA class:
@Override
public void renderChanges(Widget widget) throws IOException {
JavaScriptResponseWriter writer =
ContextProvider.getStateInfo().getResponseWriter();
writer
.write("$('#"
+ WidgetUtil.getId(widget)
+ "').bind('mousewheel', function(event, delta, deltaX, deltaY) {alert('wtf!!');});");
...
}
I have imported jquery and mousewheel plugin. I don't how rap works since I can't see any script(for widgets) written by JavaScriptResponseWriter on the client. It seems that these scripts(for widgets) will be evaluated internally.
any advice? Thanks for your attention.

Hi.
You won't be able to access the client widgets with jquery just like
that. I'm not sure what you want to do exactly, but i recommand you to
look at http://wiki.eclipse.org/RAP/ClientScripting. This project is in
very early development. Its currently missing Java API, which should be
there in a week or so. After that, any questions or suggestions for this
project are welcome.
greetings,
Tim

There is for me, but it now seems to me its not relevant for your issue.

I suggest you open an enhancement request on our bugzilla, we can
continue discussion there. Describe what API is missing and perhaps what
your usecase would look like.
Greetings,
