[news.eclipse.platform.swt] Re: No common IList interface for List and C

["Grant Gayed" <grant_gayed@xxxxxxxxxx>]

Hi,

Interfaces like these don't exist in swt.  They have been requested before
(eg.- https://bugs.eclipse.org/bugs/show_bug.cgi?id=4394 ), but in the
interest of keeping the toolkit minimal they've never gained favour.  So I
don't think it's worth submitting a new request.
