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

Hi Tim
There's no content now in the page you provided. Maybe wait for some time.
What I want to do is to add mousewheel listener to canvas. On RCP, we have a canvas which can be zooming with mousewheel event. This does not support in RAP. So I try to do it myself.
The solution I thought is implementing a customized LCA class for the canvas, adding the mousewheel listener and in the handler of js, sending the request to server(this seems possible).
Do you have any idea about this? Thanks for your reply.
Thanks
