posta o código pra gente dar uma olhada… fica mais fácil
Ola…
coloca isso no frame que vc quer que não feche pelo x.
suajanela.setDefaultCloseOperation(JFrame.DO_NOTHING_ON_CLOSE);desta forma quando o usuario clicar no x do frame, nada acontecerá…
vc pode usar um JInternalFrame e retirar o x do Frame também.
Tou com problema tenho um a tela de login quando aperto no X na barra de titulo ele abre o sistema como faço qdo aperto X feche, quero somente qdo dar login!!!
