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!

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
