Hello, everyone. I'm really new to Eugenia and I may have a silly question Embarrassed

My editor is almost done, and what I'm trying to do right now is simply change the color of the links (@gmf.link) label text, to make they look different from the nodes (@gmf.node) label text (both are black by default). Is it possible to do that through Eugenia annotations or any other way? I couldn't find any annotations in the Tutorial [1] to handle this, just change the color of the nodes border and background, which won't help as that's not the case (and also because I'm using SVG images instead of the regular shapes).

In the attached image you can see that we can easily confuse the links label text with the nodes label text. So I would like to change the links label text color to gray.

The next step in the editor is implementing some EVL rules and I'll probably need you guys to help me again when I get there Very Happy

Kind regards,
Marcos

Hi Marcos,

You will need to write a polishing transformation to achieve this [1].

Dimitris,

Thanks for your help.

I went through the tutorial you suggested and tried to write an EOL transformation rule to change one of the label's text to italic instead of changing its color, just for testing, as I found an example to do that in another tutorial [1]. So I adapted the code to this one:

-- Add italic font to hasSubFSSLabel
var hasSubFSSLabel = GmfGraph!Label.
	selectOne(r|r.name='HasSubFSSLabelFigure');
hasSubFSSLabel.font = new GmfGraph!BasicFont;
hasSubFSSLabel.font.style = GmfGraph!FontStyle#ITALIC;


However, I'm facing an error while generating the editor. The log file says:

!ENTRY org.eclipse.epsilon.common.dt 4 0 2015-12-09 15:05:47.511
!MESSAGE Called feature font on undefined object
	at (/home/marcos/epsilon-workspace2/ssmm/model/ECore2GMF.eol@4:0-4:45)


Any clue on what's happening? I guess the rule is wrong and can't select the object properly.

Hi Marcos,

That's right. There doesn't seem to be a Label named "HasSubFSSLabelFigure" in your .gmfgraph model. You may want to open your .gmfgraph model with Exeed to see exactly what is in it [1].

Cheers,
Dimitris

I corrected the name of the label to the one I found using Exeed:
index.php/fa/24256/0/

Now the rule is like:
-- Add italic font to hasSubFSSLabel
var hasSubFSSLabel = GmfGraph!Label.
	selectOne(l|l.name='HasSubFSSLabelLabel');
hasSubFSSLabel.font = new GmfGraph!BasicFont;
hasSubFSSLabel.font.style = GmfGraph!FontStyle#ITALIC;


But the problem persists. Same error:
!ENTRY org.eclipse.epsilon.common.dt 4 0 2015-12-09 15:43:32.888
!MESSAGE Called feature font on undefined object
	at (/home/marcos/epsilon-workspace2/ssmm/model/ECore2GMF.eol@4:0-4:45)

Could you please share a copy of your annotated Emfatic metamodel so that I can investigate?

Cheers,
Dimitris

... your code should read GmfGraph!Label.all.selectOne(...)

This was the problem indeed. The following script works fine for me.

-- Add italic font to hasSubFSSLabel
var hasSubFSSLabel = GmfGraph!Label.all.
	selectOne(l|l.name='HasSubFSSLabelLabel');
hasSubFSSLabel.font = new GmfGraph!BasicFont;
hasSubFSSLabel.font.style = GmfGraph!FontStyle#ITALIC;


Cheers,
Dimitris

Dimitris,

That was exactly that!

I was following a 2009 tutorial (yours, by the way) and trying to mix it with the new one.

Thank you very much for your help. Now I only have to find a way to change the label text color Very Happy (or maybe leave it just italic)
