Since deleting a diagram is something serious that could cause loss of work if done by accident, & umbrello; will ask you to confirm the delete operation before actually removing the Diagram. Once a diagram has been deleted and the file has been saved there is no way to undo this action.
Com que esborrar un diagrama és una cosa seriosa que pot causar la pèrdua de treball si es fa accidentalment, & umbrello; us demanarà que confirmeu l' operació de esborrat abans d' esborrar realment el diagrama. Una vegada que s' hagi esborrat un diagrama i s' hagi desat el fitxer no hi ha forma de desfer l' acció.
