Hi,

I know this question have been asked tons of time, but I will ask again:
Is there anywhere a good example of EMF + GEF usage. The only complete
example I found is the shape example and I think it is the worst example
ever !!! I mean it is really confusing : it explains how to make
graphical editor containing shapes on a shape business model...that's
crazy !

Best regards.

org.eclipse.gef.examples.ediagram is an excellent example.

Personally, I like it.. you certainly learn the distinction between
edit part and domain objects!

Hey Man

Did you try out the IBM RedBook example that talks about EMF + GEF together.

Hi,

Sure, I tried it and I think it is not well written. I would have
expected a clear step-by-step how-to but all I found is a bunch of
information given an arbitrary order...I don't get it.

Regards.

Hi,

I'm looking for an step by step tutorial too. I'm trying to build my own
grafical editor.

Any source code to look at?

Thanks

Hello exquisitus,

I suggest you to try GMf project (http://www.eclipse.org/modeling/gmf/) the
idea of this project is to simplify EMF-based GEF diagram development, so
you can probably use it.

I want to make an editor that paints labeled boxes, with a fixed position,
one below each other. Really it would be like a graphical tree.

How can I make this? what is the better option, using gmf or directly gef?

I'have been looking differents tutorials about gef and gmf but I need more
info to do what I want.

thanks

Hello Alex,

I have used GMF for a while but, unfortunately, it is limited for what I
want to do. I think GMF fits well I you have to develop one view for one
metamodel. In the case you want to develop several views for one
metamodel, you have to get back to GEF. I have read the new book written
by Richard C. Gronback (http://my.safaribooksonline.com/9780321591364)
showing development of BPEL language. In its approach, it mixes several
metamodels, each one dedicated to a view (the examples are available in
the eclipse cvs). I don't think coupling business models and views is a
good approach.

regards.

EMF is not enough for that ?

Finally, it is an improved Shape example. It still mixes concerns. Can
anyone give a good example avoiding mixing concerns ???

Hi,

I've downloaded org.eclipse.gef.examples.ediagram but it has compilation
errors.

They are only few of them. You can easily correct them.

Hello roeclipse,

If you you need diagram editor capable to modify EMF model (these boxes are
stored there..) then I suggest you using GMF.

Hello exquisitus,

Well, it's your choice, but I think if you are working with EMF and going
to create diagram editor it definitely make sense to start working with GMF.
You have to solve all these problems even with GEF, so GEF will not help
you to spread different model views across several diagrams... In the same
time it is definitely possible to modify GMF-generated code to make it working
in accordance with the requirements and I’m still thinking that some part
of the jobe will be done for you by GMF (both – framework and generator)..

Hi,

finally, I have found a really good tutorial based on a step by step
example. You can download the learning material following this link:
