Frank Benoit <keinfarbton googlemail.com> Thank you, yidaby. I added your snippets http://www.dsource.org/projects/dwt-samples/browser/jface/snippets/Snippet040TableViewerSorting.d?rev=88%3A9ed020f0c2a5 And to workaround the forward reference problem, i changed the CellEditor. http://www.dsource.org/projects/dwt-addons/changeset/69%3A07b9d96fd764 Then i also added the compareToIgnoreCase to dwt-win/dwt-linux dwt.dwthelper.utils There are a lot of problems with anonymous and nested classes in DMD. This is why i did move all those classes to top level scope. It seems works now. I tested it on linux.
