[news.eclipse.platform.rcp] Re: A sensible way of registering events on

[Tom Bradshaw <breadlord@xxxxxxxxx>]

Thankyou - sorry to ask the obvious followup questions, but where would

them, or would you have the view implement them. Can I have a couple of 
code snippets? I'm sorry, but I'm very new to UI design in general...
