Hello
I am working on a project with graphiti and having some problems. In my editor there are the elements "Variable" and "Pipline", based on EClasses from my Domain Model. I can add both to my diagram.
What I want is that the "Variable" objects can be added as children to a "Pipeline" object, but I don't know how to do that. Couldn't find any help in the tutorial or in the forum so far. The code for the create classes for "Variable" and "Pipeline is below.
public class CreateVariableFeature extends AbstractCreateFeature {
public CreateVariableFeature(IFeatureProvider fp) {
super(fp, "Variable", "Create Variable");
}
public boolean canCreate(ICreateContext context) {
return getBusinessObjectForPictogramElement(context.getTargetContainer()) instanceof Pipeline;
}
public Object[] create(ICreateContext context) {
Variable newClass = ModellFactory.eINSTANCE.createVariable();
getDiagram().eResource().getContents().add(newClass);
String newClassName = "Variable";
if (newClassName == null || newClassName.trim().length() == 0) {
return EMPTY;
}
newClass.setName(newClassName);
addGraphicalRepresentation(context, newClass);
return new Object[] { newClass };
}
}
public class CreatePipelineFeature extends AbstractCreateFeature {
public CreatePipelineFeature(IFeatureProvider fp) {
super(fp, "Pipeline", "Create Pipeline");
}
public boolean canCreate(ICreateContext context) {
return context.getTargetContainer() instanceof Diagram;
}
public Object[] create(ICreateContext context) {
Pipeline line = ModellFactory.eINSTANCE.createPipeline();
getDiagram().eResource().getContents().add(line);
String newClassName = "Pipeline";
if (newClassName == null || newClassName.trim().length() == 0) {
return EMPTY;
}
line.setName(newClassName);
addGraphicalRepresentation(context, line);
return new Object[] { line };
}
}
I hope someone can help me. Thank you.

If you mean adding in the editor shape tree instead of adding in EMF, then the create call of the outermost container shape is the point that you should change.
In the 'add' tutorial
ContainerShape containerShape =
peCreateService.createContainerShape(targetDiagram, true);
