Hi,
My application currently uses emf and I'd like to display some
of the objects graphically via gmf. At this point, I'm not
interested in saving modifications to the views and would like
to build the diagram from in memory objects (rather than from
a file). From reading suggestions on this newsgroup, I currently
can read in and display objects by creating my own
IStorageEditorInput and IDiagramDocumentProvider (to circumvent
having to use a file as input).
However, it's quite a hack (I'm sure I don't have them implemented
correctly) and I can't help wondering if there's a simpler way to
visualize my emf objects?
My code looks like:
// invoke the editor
MyStorageEditorInput input = new MyStorageEditorInput(domainObjectRoot);
readonlyEditor = page.openEditor( input, MyDiagramEditor.ID);
MyDiagramEditor.setInput(IEditorInput input)
{
// create diagram with input containing root object
TransactionalEditingDomain editingDomain = createEditingDomain();
ResourceSet resourceSet = editingDomain.getResourceSet();
final EObject myRootObj =
((MyStorageEditorInput)input).getDomainObject();
final Resource diagramResource = resourceSet.createResource(
URI.createPlatformResourceURI(dummyFile.getFullPath().toStri ng()));
List dummyFiles = new LinkedList();
AbstractTransactionalCommand command = new AbstractTransactionalCommand(
editingDomain, "Create new diagram", dummyFiles)
{
protected CommandResult doExecuteWithResult(IProgressMonitor monitor,
IAdaptable info)
throws ExecutionException
{
Diagram diagram = ViewService.createDiagram(myRootObj
MyRootEditPart.MODEL_ID,
MyDiagramEditorPlugin.DIAGRAM_PREFERENCES_HINT);
}
};
OperationHistoryFactory.getOperationHistory().execute(comman d,
new NullProgressMonitor(), null);
super.setInput(input);
}
Is there a way to invoke this editor without needing to
implement my own IStorageEditorInput and IDiagramDocumentProvider?
thanks,
Keith
