Editing diagram programatically [message #492109]

Hi guys,

I have a diagram and I need to create a similar one. I am already
creating the file, but it is empty. How can I put the elements there?

Does anyone can help?

Thanks,

Hi,

you can getContents from one and addContents to the other EResource.

Thanks Aurelien,

I am trying to do like you said.

To get the original resource, i am doing like this:

TransactionalEditingDomain editingDomain =
GMFEditingDomainFactory.INSTANCE .createEditingDomain();
URI uri = URI.createFileURI(diagramPath.toPortableString());
Resource diagramResource = editingDomain.getResourceSet().getResource
(uri, false);

Then, I add in the second one:
if (object2 instanceof Diagram) {
diagram.getContents().remove(object);
diagram.getContents().add(object2); }

But it is not working...
What is worng?

The problem is my getResource() is returning null. I don't know Why.

This is the code:
TransactionalEditingDomain editingDomain =
GMFEditingDomainFactory.INSTANCE.createEditingDomain();
URI uri = URI.createFileURI(diagramPath.toOSString()); Resource
diagramResource = editingDomain.getResourceSet().getResource(uri, false);

I think that the createFileUri with the toOSString may bot give you the right uri

It is because a have a Path and need to transform into URI, so i did this.

How Is the use of GMFEditingDomainFactory? I think I am doing wrong,
because there is no Resource in the ResourceSet when I looked in debug.
