Hi,

I'm trying to programmatically create and open a diagram based on an emf model that I have created.

This EObject is contained in an other EObject, i create the EOBject using the factory:

xyzFactory.eINSTANCE.create....

Then I add it to the parent object.
All these objects are in the same xml file (including the parent's diagram).

My problem is that I can't create the diagram in the same file.

I have tried using the same code as in performFinish() from the generated xyzNewDiagramFileWizard class but the diagram is created in an other file, if i give him the uri of the EObject it erase my file (even if the diagram is correctly opening after that)

here is the code i use from performFinish:

List affectedFiles = new LinkedList();
//using an other uri
		String diagramFile  = "/My Processes/"+form.getName()+".form_diagram";
		URI diagramModelURI = URI.createPlatformResourceURI(diagramFile, true);
		ResourceSet resourceSet = getEditingDomain().getResourceSet();
		final Resource diagramResource = resourceSet.createResource(diagramModelURI);
		
		AbstractTransactionalCommand command = new AbstractTransactionalCommand(
				getEditingDomain(),
				"",
				affectedFiles) {

			protected CommandResult doExecuteWithResult(
					IProgressMonitor monitor, IAdaptable info)
					throws ExecutionException {
				int diagramVID = ProcessVisualIDRegistry
						.getDiagramVisualID(form);
				if (diagramVID != FormEditPart.VISUAL_ID) {
					return CommandResult
							.newErrorCommandResult(Messages.ProcessNewDiagramFileWizard_IncorrectRootError);
				}
				Diagram diagram = ViewService.createDiagram(
						form,
						FormEditPart.MODEL_ID,
						FormDiagramEditorPlugin.DIAGRAM_PREFERENCES_HINT);
				diagramResource.getContents().add(diagram);
				diagramResource.getContents().add(diagram.getElement());
				return CommandResult.newOKCommandResult();
			}
		};
		
		try {
			OperationHistoryFactory.getOperationHistory().execute(command,
					new NullProgressMonitor(), null);
			diagramResource.save(ProcessDiagramEditorUtil.getSaveOptions());
			ProcessDiagramEditorUtil.openDiagram(diagramResource);
		} catch (ExecutionException e) {
			FormDiagramEditorPlugin.getInstance().logError(
					"Unable to create model and diagram", e); //$NON-NLS-1$
		} catch (IOException ex) {
			FormDiagramEditorPlugin.getInstance().logError(
					"Save operation failed for: " + diagramModelURI, ex); //$NON-NLS-1$
		} catch (PartInitException ex) {
			FormDiagramEditorPlugin.getInstance().logError(
					"Unable to open editor", ex); //$NON-NLS-1$
		}


Have you an idea?
Thanks you by advance for your help!

Hello Baptiste,

> String diagramFile = "/My
> Processes/"+form.getName()+".form_diagram";
You have to open resource where EObject is located here.

> final Resource diagramResource =
> resourceSet.createResource(diagramModelURI);
use resourceSet.getResource(diagramModelURI, true);
here instead of creating new resource.

> diagramResource.getContents().add(diagram.getElement());
do not add diagram element to the resoruce content - it is already there.

Thank you it helped a lot

I did this:
// add the form to the task
		task.getForm().add(myForm);

		//create the diagram
		int diagramVID = ProcessVisualIDRegistry.getDiagramVisualID(form);
		if (diagramVID != FormEditPart.VISUAL_ID) {
			// error
		}
		Diagram diagram = ViewService.createDiagram(myForm,
				FormEditPart.MODEL_ID,
				FormDiagramEditorPlugin.DIAGRAM_PREFERENCES_HINT);
		myForm.eResource().getContents().add(diagram);

		// save the ressource
		try {
			task.eResource().save(ProcessDiagramEditorUtil.getSaveOptions());
		} catch (IOException e) {
			FormDiagramEditorPlugin.getInstance().logError(
					"Save operation failed for: " + task.eResource(), e); //$NON-NLS-1$
		}
		


Now i'm trying to open the Diagram but with it open the whole resource file even if I give him the uri with the fragment corresponding to my diagram:

		//open the diagram
		try {
			URI uri = EcoreUtil.getURI(diagram);
			Resource res = editingDomain.getResourceSet().getResource(uri, true);
			FormDiagramEditorUtil.openDiagram(res);
		} catch (PartInitException e) {
			FormDiagramEditorPlugin.getInstance().logError(
					"Unable to open editor", e); //$NON-NLS-1$
		}

this open the parent's diagram in the sub-diagram editor (???)

Thank you again for your help, and if you have an idea it would be great!

Hello Baptiste,

> FormDiagramEditorUtil.openDiagram(res);
I do not have FormDiagramEditorUtil in my workspace..

I suggest you using IWorkbenchPage.openEditor(URIEditorInput(), <editorID>);
for openning diagram editor.

Hi,

I am trying to create a diagram programatically, like you. What is this
task that you used?

Here:
> // add the form to the task
> task.getForm().add(myForm);


Thanks,

"task" is one of my EObjects, i juste add an Element to another one.

I've made 2 functions to do the creation and the opening of the diagram


	public Diagram createDiagram(XXX xxx){
		//create the diagram
		int diagramVID = ProcessVisualIDRegistry.getDiagramVisualID(xxx);
		if (diagramVID != FormEditPart.VISUAL_ID) {
			// error
		}
		Diagram diagram = ViewService.createDiagram(xxx,
				XXXEditPart.MODEL_ID,
				XXXDiagramEditorPlugin.DIAGRAM_PREFERENCES_HINT);
		xxx.eResource().getContents().add(diagram);

		// save the ressource
		try {
			xxx.eResource().save(XXXDiagramEditorUtil.getSaveOptions());
		} catch (IOException e) {
			XXXDiagramEditorPlugin.getInstance().logError(
					"Save operation failed for: " + xxx.eResource(), e); //$NON-NLS-1$
		}
		refresh();
		return diagram;
	}
	

	public void openDiagram(XXX xxx){
		//open the diagram

		try {
                //find the diagram in the resource
			Diagram diag = null;
			EList<EObject> resources = xxx.eResource().getContents();
			for (EObject eObject : resources) {
				if(eObject instanceof Diagram){
					if(((Diagram)eObject).getElement()!=null  && ((Diagram)eObject).getElement().equals(xxx)){
						diag = (Diagram)eObject;
						break;
					}
				}
			}
                   //open it
			URI uri = EcoreUtil.getURI(diag);
			IWorkbenchPage page = PlatformUI.getWorkbench()
			.getActiveWorkbenchWindow().getActivePage();
			page.openEditor(new URIEditorInput(uri,xxx.getName()), XXXDiagramEditor.ID);
			
			
		} catch (PartInitException e) {
			XXXDiagramEditorPlugin.getInstance().logError(
					"Unable to open editor", e); //$NON-NLS-1$
		}


It's better to execute them in a command.

tell me if you have troubles with it

Hi Baptiste,

I am currently trying to implement the following behaviour:

Upon the push of a button, a new model and diagram file shall be created
and the selected diagram elements shall be stored in those files.

It looks like that's what you are doing, although I'm not entirely sure.
Can you help me with implementing the things above? I do not know how to
create new files and store things in them from eithin the run method of
my action.

Regards,
Matthias

Hi Matthias,

Here is a snippet of code doing the thing in the execute method of an
AbstractHandler:

public Object execute(ExecutionEvent event) throws ExecutionException {
try {


IProject project = //retreive your IProject

URI newProcessURI =
URI.createPlatformResourceURI(project.getFile("your file
name").getFullPath().toString(), false);
Resource diagram = XXXDiagramEditorUtil.createDiagram(newProcessURI,
new NullProgressMonitor());
if (diagram != null) {
try {
XXXDiagramEditorUtil.openDiagram(diagram);
} catch (PartInitException e) {
ErrorDialog.openError(Display.getDefault().getActiveShell(),
"Open New Diagram",
null, e.getStatus());
}
}




return null;
} catch (Exception ex) {
ex.printStackTrace();
return null;
}
}

As you can see here you should reuse generated Util functions.
Good Luck

Romain
