From my understanding, GMF can generate an editor from EMF model. I have two
questions, would be grateful if anyone can shine some lights.
1. Is there API that I can compose the relation in a graph beforehand if I
already how the components are connected, and ask GMF to take that input and
draw it out?
2. After GMF generated the editor and user composes the graph, in what
format can the graph has saved? From GEF shape example, it is saved in
binary form. Can it be saved in XML format possible? Is there any example
for this?
Thanks,
Agatha

Hi Alex,
When I access the Callisto Webinar, it seems the dialog is saved as mmd file
which looks to be a binary file.. Are you sure it is saved as XMI format?
For Q #1, does it means I should compose GMF input in XMI format on the fly?
I am unsure what you mean by writing custom code to ensure it is compatible
with gmf.runtime.notation and draw in optimal position. Are you suggesting a
program or an XMI file?
I though it is similiar to generate ecore_diagram from ecore.. So Eclipse
can provide API on how to compose the GMF input. Are there schema or DTD
file that I should follow when compose the XMI file?
BTW, I hit an error in the mindmap example, I have started another thread on
that.
Thanks!!

Hi Alex,
I finally get mindmap to work, and yep it is saved as *.mindmap_diagram so
you are right that it is in XMI format.
So, now I only leave you with question #2...

Which API, can you elaborate? Would be helpful if you can give an example..
Many Thanks!

If we are talking about diagram information (position/size of the nodes,
links bending points, colors, ..) this information is available in Notation
model: org.eclipse.gmf.runtime.notation plugin, package with the same name.
Take a look on View, Node, Diagram, Edge interfaces in this package.
