}

i mam w niej button który dodaje imię i nazwisko jako jeden wiersz, a chciałbym też mieć button usuwający wiersz (imię i nazwisko), wszystkie wiersze oraz pobierający ostatni wiersz do pol tekstowych w celu jego edycji, z góry wielkie dzięki za pomoc :)

stwórz te buttony i obsłuż identycznie jak w przypadku addButton z tym że zamias metody add użyj remove, clear albo set.

ok, mam add, del, delall i quit button tylko chciałbym żeby del usuwał ostatni dodany a nie pierwszy a add blokował dodawanie pustych row
