How to delete view programmatically of a given DDiagramElement [message #1722931]

Hi,

I am looking for an API to delete the view of a given DDiagramElement, doing the same thing that the "Delete View" tools in the ViewpointSpecificationEditor.

How can I do that programmatically ?

many thanks in advance,
Benoît

Hi Benoit

Did you try the simplest operation?

final DDiagramElement element = ...
// alternative1: EcoreUtil.remove(element);
// or better, alternative2
SiriusPlugin.getDefault().getModelAccessorRegistry().getModelAccessor(element).eRemove(element);

You will need these dependencies in order to access ModelAccessor:

org.eclipse.sirius
org.eclipse.sirius.ecore.extender

I guess it will work fine if you execute this code in a command (this is ok if the operation is executed into a Java Service called by Sirius or an ExternalJavaAction). Of course, the mapping of the deleted view must be unsynchronized or Sirius will recreate the view during the next refresh.

Cheers,
Yann
