Hi everyone,

I have created the Initial State with this FigureDescriptor.
index.php/fa/6261/0/
<descriptors
name="InitFigure">
<actualFigure
xsi:type="gmfgraph:Ellipse"
name="InitFigure">
<foregroundColor
xsi:type="gmfgraph:RGBColor"/>
<backgroundColor
xsi:type="gmfgraph:ConstantColor"
value="black"/>
<preferredSize
dx="22"
dy="22"/>
<insets
top="5"
left="5"
bottom="5"
right="5"/>
<border
xsi:type="gmfgraph:MarginBorder">
<insets
top="5"
left="5"
bottom="5"
right="5"/>
</border>
</actualFigure>
</descriptors>

Now I want to create the Final State the same as this one:
index.php/fa/6262/0/

But it seems that I have problems with designing the GMF Graph for this state. I am new to Draw2d. Someone please could help me figure out how to do so?
The Final State is slighly bigger than the Initial State. I think it's 30x30, compares to 22x22 of Initial State.

Thanks,

Hi everyone,

Is the question lack some details or no one is interested in giving the answer?

If you want to test the graph then you can navigate to this GitHub project: https://github.com/pnhoang/Selflet
Import the SelfletBehavior* projects and then you will be able to test your change.

I am thinking of putting the .svg file as the default image, but I am eager to also learn how to draw in draw2d with this specific situation. Thanks.

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.

Hi Mickael,

Thanks for the response, I have dropped a message in the bug report for previewing the figure at design phase. I think it's very helpful.

I know that Draw2d has the same principles with SWT, but I am new to this Java world in general. That's the point. But thanks for your suggestion, I will come back to learn SWT before proceeding ahead.

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.

Not sure if it matches your use case, but documentation tells an easier
way to leverage SVG Figures:

Hi Mickael,

Somehow I enjoyed hacking the .diagram project than installing an Experimental SDK. Is that part of the tutorial still valid (i.e. installing the Experimental SDK, )? In the previous section, I tried to use the ImageFigure as suggested but did not see any ImageFigure in the gmfgraph.

Sure, that's a good thing to learn. However, you'll discover that the
less you modify generated code, the more agile you are. Then you'll like
to see simple way to achieve things by configurating GMF files ;)
Don't be afraid of using the experimental SDK, it is not that much
"experimental", it has the same level of quality than the rest of GMF.
You can rely on it for your apps without risks.

> Is that part of the tutorial still valid?

I hope so, this is the main tutorial and docuementation.

Indeed, there is no such ImageFigure in gmfmap. I updated the wiki to
fix that.
Here are more relevant inputs about ImageFigure:

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,
