I have implemented commands for creating and moving/resizing edit parts.
This seems to work fine. Do I need to do anything to enable the undo/redo
menu items in Eclipse when I add something to the command stack? I am
using XYLayoutEditPolicy like the logic example. I can see that my
commands get added to a stack in DefaultCommandStack::Execute(), but I can
not figure out how to enable the undo so I can get the framework to call
the undo and redo of my commands.

Can someone point me to some documentation on how the command processor
works in eclipse and how plug-ins like gef fit into this?

Thank you,

Well, if you sommands support Undo and Redo you just need to
activate/register the default Actions. Look at the Logic example. I'm not at
work and so have not the right source in front of me. Maybe you must supply
and ActionContributor class with your editor.

You do need to specify a "contributorClass" in your plugin.xml file. You
can use GEF's ActionBarContributor to get undo, redo, save, and delete
support. Or you could subclass it to add your own actions (see
LogicActionBarContributor).

Works like a charm. I was using a basic text editor contributor class
that I must have copied from the readme example.

Merci beaucoups!
