Hi all. I'm relatively new to swt so I apologise for the dull question,
but can anybody point me in the direction of an manuals, tutorials, and/or
examples of how to implement undo/redo function.

I have eclipse plug-in example's, being the Box View and Undo History
View, but neither have helped me understand the development process.

Thanks in advance.

PS. I've tried the obvious routes of the eclipse site, googling it etc, to
no avail.

What is it that you're trying to undo/redo? Unless it's graphics
operations on a SWT canvas, you're probably better off asking in the
eclipse.platform newsgroup.

Eclipse 3.1 has the new IUndoableOperation framework that you may find
interesting -
http://help.eclipse.org/help31/index.jsp?topic=/org.eclipse. platform.doc.isv/reference/api/org/eclipse/core/commands/ope rations/package-summary.html
You should be able to search for references for these classes to find
examples of uses. It's also common to use GEF's commands to perform undo
operations in graphical editors.

Hope this helps,
- Jeff
