public abstract class ActionBaseDelete
extends UMLAction

Action for removing (moving to trash) objects from the model. Objects can be: - Modelelements - Diagrams (argodiagram and it's children) The root model and the last diagram in the project can not be removed. The reason for this is to prevent problems updating the detailspane and the navpane. Besides that, it is not possible to make a new root model.
