[news.eclipse.platform] getting IResource objects for all files in an IR

["Marc E" <marc_e@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx>]

I've got a ResourceSelectionDialog that can return a folder, and so I can 
cast the getResult() to an IResource. Now, what I want to do is get the 
IResource objects for all files inside that folder. I started to do it with 
just casting that to a File object and doing a listFiles(). But then i've 
gotta go through the rigamarole of turning those File objects into resources 
and quite frankly i'm not having any luck.

In the end, my goal is to get the project-relative path for each of those 
files (i.e. for each file resource, call resource.getProjectRelativePath())

But I figure there's probably an built-in mechanism in eclipse for doing 
this already since this seems like it'd be a fairly common thing.

Any help is greatly appreciated.

Thanks.
