[news.eclipse.platform.swt] Re: When can setFocus return false?

["Grant Gayed" <grant_gayed@xxxxxxxxxx>]

Hi Michal,

There are a few contexts where controls don't take focus, but your case of a
Text not taking it but then taking it in an immediate re-try sounds strange.
Are you able to provide a snippet that shows this happening (example snippet
template: http://www.eclipse.org/swt/faq.php#whatisasnippet )?  Can you see
if this still happens with a recent eclipse/swt like
http://download.eclipse.org/eclipse/downloads/drops/S-3.4M6a-200804091425/index.php ?
