Witam, w wolnych chwilach, ćwiczę sobie pisanie i pracę z NetBeans7(świetna rzecz ) wyprodukowałem kod nawet działa, chodzi o to że wszystkie zmiany czcionki, koloru itd zachodzą dla całego EditorPane a nie powinno tak być, jak zmodyfikować kod by to zmienić? Z góry dziękuje wszystkim sympatykom Javy za pomoc.Sam zabieram się za poszukiwania.
