Hello everyone!

I'm creating some graphical editors with EuGENia. My problem is that I need create a node with 2 labels, one of them to show the name (EAttribute) and another one must be show a fixed text (not EAttribute).

I don't know how to do, any ideas??

Thank you,
ajimenezr

Hi,

You can specify the first label (the one that is bound to the EAttribute
) in the @gmf.node(label="...") annotation. Then you need to add the
second label in your .gmfgraph model via a polishing transformation as per:

http://www.eclipse.org/gmt/epsilon/doc/articles/eugenia-poli shing/

If you have trouble with this, please send your metamodel and a drawing
of how you want your node to look like and I'll be happy to help.

Cheers,
Dimitris

Hi again,

I've already known your idea (I created another editors using GMF) but I want to create all through emfatic code and EuGENia plugin, but I don't know if it is possible:

Could I create a complex editor using only emfatic code and EuGENia?

Thanks,

ajimenezr

Hi,

As explained in
http://eclipse.org/gmt/epsilon/doc/articles/eugenia-polishin g/ , EuGENia
doesn't provide a 1:1 mapping with GMF (if it did, it would be as
complex as GMF and this would beat the whole point).

Its aim is to support the most commonly used features of GMF using
annotations so that you can get a working and fairly complete editor
very quickly, and then provide you with a systematic way of polishing
your editor.

So the short answer is that you can create an editor up to a certain
level of complexity with the built-in annotations, but you then have to
use the polishing transformations if you need to go any further.

In case it helps, in addition to the example above, the following two
examples also use polishing transformations:

http://eclipse.org/gmt/epsilon/examples/index.php?example=or g.eclipse.epsilon.eugenia.examples.endlabels
http://eclipse.org/gmt/epsilon/examples/index.php?example=or g.eclipse.epsilon.eugenia.examples.flowchart

Cheers,
Dimitris

Hi Dimitris,

your answer is perfect!

"Its aim is to support the most commonly used features of GMF using

Thank you very much!
