[SouJava-J] Thread que modifica JText

[Jorge Fl�vio]

Ol� a todos . Tenho uma pequena d�vida : eu tenho um JTextField dentro de um
JFrame  numa classe. Dentro do mesmo arquivo tenho uma classe que extende
Thread.
Quero saber como modificar o valor do JTextField de dentro da classe
BtnThread ; seria interessante
que BtnThread recebesse como argumento o JText e modificasse a vari�vel do
JTextField correspondente.
A� vai o c�digo-fonte, baseado num sample do JBuilder :
Obrigado a todos.
