I'm exploring GMF for an upcoming project.

We would like to be able to drop palette items into a tree based editor.
Any samples or tutorials that show how you might have a graphical tree view
based editor derived from the generated diagram code that you get from gmf?
Anyone gone this route in their own development?

thank you

I was exploring changing my editors base view from a
ScrollingGraphicalViewer to a TreeViewer inside my generated editor code by
overriding CreateGraphicalViewer, but it seems alot of work to replumb this
and it doesn't appear the code is setup to handle changing the graphical
view out of the editor.

There are a number of references in the generated code that assume it is
dealing with the expected DiagramGraphicalViewer which derives from
ScrollingGraphicalViewer as well as a number of places the view is cast to
this class.

public class DiagramGraphicalViewer
extends ScrollingGraphicalViewer.

Is this not the way to go? Is there a way to take the generated code and
mimic a tree view within my editor or should I abandon the generated code
and roll my own editor?

If you need emf model editor that represents your model as a tree why
don't you use the one generated by emf.edit from genmodel? It's not that
hard to write palette for it )))

Neil, if you are interested in a tree viewer for your domain model you
can always get one for "free" from the EMF Project.

Here's a link to a tutorial:
http://dev.eclipse.org/viewcvs/indextools.cgi/*checkout*/org .eclipse.emf/doc/org.eclipse.emf.doc/tutorials/clibmod/clibm od.html

If you need further assistance just let me know.

Regards,
Angel Roman
