Something like Spy++ for SWT?

I am looking for something like Spy++ but for SWT. I know there are solutions that help you out when you want info about Eclipse's plugins, so I guess this must be somewhat possible.

In my specific case, I'd need a way to Spy on code other tha my own (like Spy++ allows you to), so I guess Eclipse's plugins aren't going to help me out here!

Thanks

You mean, something like SWT Spy?
