[news.eclipse.newcomer] Doubleclickevent for SelectionDialog

[Christian Weyand <newsgroup@xxxxxxxxxxx>]

Hello Newsgroup,
i've written a SelectionDialog, which list's all items in a tree. I'd 
like to add a DoubleClickListener to this dialog, so it's more handy to 
use - but can't find any information in the SelectionDialog API.

Is this possible at all?

Thanks in advance,
chris
