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

[Tom Schindl <tom.schindl@xxxxxxxxxxxxxxx>]

I'd use a command and if a double-click occurs I'd execute this command 
using the ICommandServer/IHandlerService. You can then in any part of 
your system listen to the command and act upon it.

You'll also have to register your Viewer as a SelectionProvider in the 
SelectionService this way you can easily read it in any part of your RCP 
application.
