RE: [jwt-dev] JWT and GMF
|
Hi Marc, others,
I would like just to clarify my/team position: GEF is the technology we have
been paying so far so I'm not against GMF (basically because we never played
before with it).
So, what we have experimented is that GEF is something hard to learn so we
decided to also have a look to GMF (seems to be easy to start but hard to
customize) to have a better overview of this technology and so be able to
compare both with one target in mind: what is the best Eclipse technology to
build a BPM graphical editor?
In this context Rodrigue is doing some experimentation with GMF which I
think is a good complement with the work that Pierre and Marc are doing
around GEF.
BTW, Pierre is about to post on the last developments around JWT.
Best regards,
Miguel

Hi Rodrigue
GMF has been discussed already but maybe not openly (on the mailing list
etc.). It helps configure and generate a diagram and its palette. Its
good point is that it extends EMF's modeling and generation chain up to
the diagram UI. It's bad point is that UI is a field where you may want
to tinker to get exactly what you have in mind and that the configure /
generation paradigm rather gets in the way. So if your default generated
diagram is OK with you (and you've succeeded in generating it !), you've
won some time and an architecture, otherwise...
Basically, right now the existing JWT code is GEF, nobody has the
resources to rewrite it, and the main JWT architects (Florian, Miguel,
me and I suppose Pierre) dislike GMF's generation magic. I've tried a
little bit GMF and closely followed Stéphane Drapeau who at SCA Tools
has successfully used it, and it seems to me that it has a steep
learning curve, can really make tinkering difficult (for example,
Stéphane wanted to have concept icons on top of the border of another)
and would be harder to customize to support model and view
extensibility. These two last points come from the fact that like EMF,
it is aimed at creating end-user tools rather than extensible tools that
other vendors would build on.
But it really comes down to the fact that our view developers are
Augsburg's and are experts on GMF and not EMF, and that Miguel I guess
also prefers GEF right now. I personally think that making views-like
things in GMF would be way harder than in GEF and require heavy
knowledge of GMF, even possibly help it evolve.
Regards,
Marc
