You have two options:
1. Create your customshape with template points in the graph, or by code
like below.
In class: xyzEditPart
public class xyzNodeFigure extends Shape {
....
public xyzNodeFigure() {
this.setLayoutManager(new StackLayout()); this.addPoint(new
Point(getMapMode().DPtoLP(50), getMapMode().DPtoLP(0)));
this.addPoint(new Point(getMapMode().DPtoLP(100),
getMapMode().DPtoLP(50)));
this.addPoint(new Point(getMapMode().DPtoLP(50),
getMapMode().DPtoLP(100)));
this.addPoint(new Point(getMapMode().DPtoLP(0),
getMapMode().DPtoLP(50)));
this.setForegroundColor(ColorConstants.black);
this.setBackgroundColor(ColorConstants.green);
createContents();
}
2. Since the above 2D method is unsuited to figures like a cloud - you
could use an svg image. That process is described here:
http://wiki.eclipse.org/GMF_Tutorial_BPMN#Custom_Figures_.28 SVG.29
If you need to create the figure from scratch, Incscape is a great tool.
Hope this helps,
Tomas Zijdemans

Hi Tomas,
Thanks for your responses.
I tried using inkscape and followed the BPMN tutorial. However, I got some
errors.
Im posting the java code for you to view, just incase you find any errors:
The protected IFigure createNodeShape() is the method thats giving errors.
Please, I need your help. Thanks

Which version of GMF are you using, and what URL class is imported? (you'll
need java.net.URL)
This code works fine with the latest GMF:
URL url = FileLocator.find(Activator.getDefault().getBundle(), new
Path("images" + IPath.SEPARATOR + "ievent.svg"), null);
return new
ScalableImageFigure(RenderedImageFactory.getInstance(url), true, true,
true);

Hi,
Many thanks for your code and help so far.
I tried the codes, I cant just place the problem. When I used this code:
protected IFigure createNodeShape() {
URL url = FileLocator.find(ShapeDiagramEditorPlugin
getInstance().getBundle(), new Path("images/cloud.svg"), null);
return new ScalableImageFigure(RenderedImageFactory.getInstance(url),
true, true, true);
}
It kept underlining the getInstance(url) saying that it's undefined for
the type RenderedImageFactory.
When I used an alternative code:
protected IFigure createNodeShape() {URL url =
FileLocator.find(Activator.getDefault().getBundle(), new Path("images" +
IPath.SEPARATOR + "cloud.svg"), null);
return new
ScalableImageFigure(RenderedImageFactory.getInstance(url), true, true,
true);
I got 2 errors: 1. The method getDefault() is undefined for the type
Activator.
2. getInstance(url) is undefined for the type RenderedImageFactory.
Please, what further advise can you give.
Im using GMF version 2.0.1.v20071003 - 0000 Build id: 2.1M2
Thank you.
