Display containment through link [message #651393]

Hi,

I have two nodes (A and B) A is having a reference to B. This reference is set containment true. I only know how to display B inside A, but not how to make the containmen visible by drawing a line. Here is a Example:

-------         A.containment      ------
|Node A| -----------------------> |Node B|
-------                            ------

When I define a link on the containment using the target feature I cannot start drawing a line from A to B.

Does anyone know how to solve this?

Thanks in advance!

Hello Raplh,
I think there is a semantic issue in what you are trying to achieve. The ecore containment can't be map directly with your "domain" containment.
You should create a ContainmentConnection object in your domain to represent your containment relationship and map it to Connection figure.

Hope that it's clear enough

Hi Romain,

adding an extra meta model element is what I wanted to get around. Is there no way to do this by children/containment feature? I could not find a good description of those two. I have also seen, that there is a way to affix containments outside of a container but could not find any documentation, too.

Are you talking about boundary items?

Hi,

I have seen this tutorial: http://www.eclipse.org/gmt/epsilon/doc/articles/eugenia-affi xed-nodes/ . I do not know how to do this with GMF. Would it be possible to have this with a line between the outer element and the container? Maybo border items would solve my problem. My use case would be something like having a UML Class and displaying the methods and fields outside of the class. I think border items would be great as they are deleted together with the containing node. How could I realize such a thing?

Thanks!!

Hi Ralph,

it looks like phantom nodes are exactly what you need: http://www.eclipse.org/gmt/epsilon/doc/articles/eugenia-phan tom-nodes/
