how to create programatically a diagram file when we provide a model eobject.

for example, i have a model eobject named transaction, which has some children and subchildren.Now i want to create an diagram file which has nodes and edges programatically through transaction eobject.I can use a stupid way by the strong coding, but it may be very troubled.

Is there any simple way to do this? for example some useful classes and methods.

Take a look at the XXXInitDiaramFileAction in your generated diagrams plugin.
I believe GMF is generating a diagram programmatically there.

Best,

Hi,

Check generated xxDiagramEditorUtil.
You should find a static method
createDiagram(URI diagramURI, URI modelURI, IProgressMonitor progressMonitor).

From here you just need to load the existing model instead of creating a new one.

Switching

final Resource modelResource = editingDomain.getResourceSet()
				.createResource(modelURI);

for :

final Resource modelResource = editingDomain.getResourceSet().
				getResource(modelURI, true);

and deleting :

attachModelToResource(model, modelResource);

should do the trick.

Or you can modify :

private static XXX createInitialModel() {
		return XXXFactory.eINSTANCE.createXXX();
	}

to return what you want.
