Adding purely geometric shapes to a diagram? [message #72264]

I would like to be able to add purely grapical elements to a diagram
(e.g. Labels to allow to describe things or rectangles that can be used
to surround and group elements).
These graphical elements should have no semantic meaning (I mean have no
representation whatsoever in the .ecore model). Can that be (easily)
done in GMF?

And by the way: is the original source to the geoshapes example
available? The source supplied in the GMF-examples file apparently is
the *generated* source, not the actual GMF input files. I would be
interested to see how these geometric shapes were defined.

The GeoShapes code will be in the plugin
org.eclipse.gmf.runtime.diagram.ui.geoshapes, but this plugin is not a
generated plugin, it had been implemented form scratch.

Thanks for responding and for clarifying things re. the geoshapes
example!

I guess my question was more: can one specify such elements using GMF
(i.e. in a somehwat "declarative" way) and if so, how, or only by
hand-morphing/-adding to the generated code?

I find the concept of GMF very intruiging and so I want to hand-code
or -change as little as possible as long as I can achieve the same using
the misc. .gmf*-files.

Hello Michael,

It is possible to generate diagram code working with design-only elements.
The only problem is: such elements can not contain any other diagram elements
with semantic model element attached. This is a current limitation.

To get pure-design elements generated just do not specify semantic model
element for the corresponding mapping.
