This is GEF 3.0.
The LogicExample seems to have hooked into the global menu and toolbars
for Undo/Redo. Can you point me to the relevant areas of the code that
make this happen?
I have them on my right-click menu within the editor, but not on the
main menu and toolbar. Those are disabled.
Thanks

Thanks. I took a look and copied the relevant bits. However, the
toolbar and menu options still do not enable after changes are made.
The right-click menu options still work fine. So it seems like there
must be other bits in the example that control this.
Any ideas?

Hi Mark,
You're manipulating the GEF-Diagram with different Commands, right?-Then
you have to implement for every command an undo and a redo action by
overwriting #undo(), #redo() and #canUndo(). All executed commands are
on the command-stack an can be undone if the #canUndo() - method of the
special command returns true.
Cheerz,
Tom

That is just how you enable undo/redo in your model. I have that
working fine. What I am asking is a UI issue. How do I get the
Eclipse IDE undo/redo menu and toolbar enabled and connected to my
code? The Logic example appears to do it. Right now, I have to
right-click in my diagram to get to the options. I just want the other
ones enabled too.
I have done it before via brute force, but it seems like the logic
example might have a better way. I just cannot figure it out.
This is in 3.0

Have you declared the contributor-class in your plugin.xml?

I am not sure what you mean. I look at the logic example XML and all I
see is it contributing a Print action and the stuff to declare the
editor itself and the New wizard.

Disregard. I see it now.
I will give it a try.
Thanks

Actually, it turns out that Yes, I did already have that defined.
Any other ideas?

Yes, I had all of that. I finally got it working. I was doing a
couple of other things in my contributor class. I think one of these
was interefering with something or causing a side-effect. I
reorganized some of that code and then this started working.
Thanks
