It's probably that AFAIK the best way to get this working is to try and
see, but that's too much time consuming for people reading the forum.

Seems like we met that same issues about reducing development loop in
..gmfgraph:
You should have a look at this bug to help you creating your GMFGraph:
* https://bugs.eclipse.org/bugs/show_bug.cgi?id=363449
It shows you a preview of what you're creating. You can get in from the
2.4.x-maintenance branch of GIT GMF-Tooling repository. It will probably
be part of the 3.0 release, and maybe of a 2.4.1.
If you like it, drop a comment or vote for it, it will be easier for me
to convince the project lead to put it in a 2.4.1 ;)
Also I made another tool that is useful for any Draw2d figure:
http://marketplace.eclipse.org/content/draw2d-preview .
Hope you'll find them interesting. And if you're motivated, feel free to
suggest feature requests to GMF Tooling via the tracker.

Draw2d follows the same principles as SWT for layouting. Spending a
couple of hours to create some Draw2d figures by hand will for sure make
you save you even more hours in your future usage of gmfgraph.

I have finally come up with the solution to use SVGFigure to save my time.
Basically these are what I do:
- Create the SVG image by using Inskcape to convert from PNG to SVG image.
- In the .gmfgraph:
+ Add a new Figure Gallery with name : Images
+ Under this Figure Gallery, add a Figure Descriptor with name SVGFinalStateFigure
+ Under this Figure Descriptor, add a new Custom Figure name SVGFinalStateFigure, Qualified Class Name: org.eclipse.gmf.runtime.draw2d.ui.render.figures.ScalableImageFigure
+ In the Canvas of this .gmfgraph, add a new Node name SVG Final State, this Node points to the SVGFinalStateFigure created above
- In the .gmfmap:
+ Map the Node Mapping of Diagram Node to this SVG Final State (SVGFinalStateFigure)
- Transform the .gmfmap to .gmfgen
- Regenerate the .diagram project
- Add the Final.svg image created above to the .diagram project
- Add dependencies to the .diagram project org.eclipse.gmf.runtime.draw2d.ui.render
- Update the createNodeShape() function of FinalStateEditPart to the following:
/**
* @generated NOT
*/
protected IFigure createNodeShape() {
URL url = FileLocator.find(SelfletBehaviorDiagramEditorPlugin
.getInstance().getBundle(), new Path("icons/Final.svg"), null); //$NON-NLS-1$
return new ScalableImageFigure(RenderedImageFactory.getInstance(url),
true, true, true);
}
- Add the corresponding imports to this java file
- Ready to go!
The whole commit for this code is located at this GitHub page
Don't be threatened by the generated codes. Just look at the steps above and compare the codes. Some files are generated automatically by GMF Frameworks, so we don't need to care about, e.s. .gmfgen file.
The solution comes from following this tutorial. Thanks everyone.
Hope this helps someone.

Hi Mickael,
Thanks for the good advice on doing all configurations in GMF. Sometimes, I do feel that I need to use the Git rewrite history function a lot just to update the changes I made in the past to the .diagram project, because once I deleted the .diagram project, all changes I made to this project are gone. I have to rewrite the history of Git to update the changes. That's not good for an open source project.
Now I have totally get rid of the habit of deleting .diagram project when there is any error generating from the gmfgen. I feel that it's generally better to do everything in GMF configuration files.
Thanks,
