Class ShapeForbidLayoutEditPolicy

  • All Implemented Interfaces:
    org.eclipse.gef.EditPolicy, org.eclipse.gef.RequestConstants
    public class ShapeForbidLayoutEditPolicy
extends org.eclipse.gef.editpolicies.LayoutEditPolicy
    An EditPolicy, which 'forbids' any Layout dependent Commands. All methods of this EditPolicy return null, which is different from using no EditPolicy at all, because it will create a visible feedback that the requests are forbidden. This EditPolicy can for example be used for those EditParts, which do not have any children.
