Witam.
Pisze prosta aplikacje gui i natknalem sie na problem z ktorym nie moge sobie poradzic.
Bardzo prosilbym was o pomoc.
Chcialbym aby po wpisaniu imienia oraz nazwiska i kliknieciu przycisku dodaj, wprowadzone dane wpisywaly sie do textarea znajdujacego sie ponizej oraz zapisywaly sie.
Domyslam sie ze kod moze byc troche chaotycznie napisany ale to dlatego, ze jestem jeszcze dosc slaby w programowaniu i jak na razie wszystko przychodzi metoda prob i bledow. pola btn_dodaj oraz actionPerformed zostawilem swiadomie puste, poniewaz rozne proby konczyly sie niepowodzeniem.
Licze na wasza pomoc.
pozdrawiam
