JComboBox - Socorro!

MusicoPJ · Novembro 20, 2004, 12:00am

Graças a alguns amigos do portal Java consegui um tutorial para autocompletar JComboBox ao digitar, mas tive que fazer algumas alterações para se enquadrar no programa que estou fazendo, só que tem um problema: Quando se digita muito rápido, da erro ao autocompletar.
Quem puder me ajudar segue-se abaixo o código:
(Desde já obrigado).

Kra… eu não tenho certeza… mas talvez issu seja problema de threads… tenta colocar synchronized no método que pega a tecla que o kra digitou…
