Hello,

I'm looking for examples of ECF use with graphical editors (GEF or GMF).
I remember of stumbling upon an example a long time ago: a simple collaborative GEF editor, with green squares.. but i cant find it.

Could someone point me a link to an example?

thank you in advance,
Ugo

Hi Ugo,

Yes, we did have an example years ago (in 2005 I think) that was an
EMF+simple GEF-based graphical editor. It was very simple...essentially
just nodes and links between them, but it did use ECF to communicate and
synchronize state changes of the underlying model (using EMF and
notification, and ECF's messaging APIs).

I'm sad to say that we haven't been able to keep this example maintained
(it had dependencies not only on ECF, but also on EMF, GEF), and so I'm
not at all sure it will still work (or even compile) with more recent
versions of ECF, EMF, and GEF.

I'm willing to track it down in the Eclipse archives if you wish, but
I'm not sure if it's worth it given the changes that have occurred
since. Do you still want to access this (old) code? Let me know and if
so I'll find it in the Eclipse archives.

Thanks,

Scott

Guys,

Forgive me that I chime in here but maybe the new Dawn component of the
CDO Model Repository is of interest for you. Dawn is a generative
framework that augments GMF editors so that they transparently work on
top of distributed shared EMF/CDO models. Please let us know if you
would like to have more infos. Martin Fluegge will be happy to answer
them ;-)

Here's an old article about Dawn:

Cheers

Hello Scott,
I would appreciate very much if you could track those old projects for me, thank you.
I'm investigating how two GMF editors might be synchronized using ECF, to build a sort
of collaborative graphical editor. If ECF is able (and I think it is) to sync commands
between the editors, would be enough, it is really simple and the example should give me
what I need.

(I got an old 'scribble share' at the examples, on the cvs, but I could not get it to work after a few tries..)

I promise to try to fix the dead projects and patch back to you guys, if you want.
Anyway I will be working with graphical editors and collaboration quite a bit in the future,
whatever I produce is meant to be contributed back :)

Best regards,
Ugo

Hello Eike,
thank you very much, Dawn seems to fit perfectly.
The screencasts shows some really nice features

I will contact Martin regarding the implementation.

Dear Ugo,

I am doing my thesis in "Collaborative modeling editors in Eclipse".
I am looking for some examples of using ECF with graphical editors?

Could you please tell me where can I find them?




thanks,

Uma Shankar
