Hi,

I was wondering how we can delete a representation (file) ? I'm designing a dashboard so that the user can see the list of representations as a list (Similar to what is designed in UMLDesigner) !

Now, I 'm writing a java service to be run when the user hits the delete button on keyboard.

Thanks,
Best Regards,
Parsa

P.S. - The thing is that the default action of delete button of course deletes the representation, but I need to write a java service to show the confirmation dialog to the user and then delete.

Hi Parsa,

I think you might have two solutions:
. the first is to take a look to the org.eclipse.sirius.deleteHook
extension point. It will be called when the user uses the delete
menus/action/buttons.
. the second is to look into [1] & [2] and to use a ModelChangeTrigger
(will be called in pre-commit of the transaction) and to react to any
EObject detachment (delete tools, but also every other interaction which
might result in the detachment/deletion of one of your domain EObject).

Regards
