Olá Pessoal!
Ca estou mais uma vez com uma dúvida sobre eventos de botões.
Bom criei dois botões no meu jFrame um para fechar o jframe e outro para minimizar, mas não sei implementar nenhuma dessas duas funções nos botões.
criei os botões pois não quero utilizar a barrinha padrão do windows.
me ajudem ai se possível!
Ola amigo, tente assim:
para fechar: dispose();
para minimizar: JFrame.setExtendedState(JFrame.ICONIFIED);
Não funcionou o minimizar!
private void minimizarBtnActionPerformed(java.awt.event.ActionEvent evt) {
JFrame.setExtendedState(JFrame.ICONIFIED);
}
Poste o código da sua classe, dependendo de como vc está instanciando o JFrame, deverá usar assim:
this.setExtendedState(JFrame.ICONIFIED);
To postando o código do Jframe todo pra ver se você encontra algum erro amigo.
Desde já muito obrigado.

} E SE no lugar de um JFRAME fosse um JDIALOG?
Amigo, para o JDialog não existe essa possibilidade, pois o mesmo foi criado para ser uma janela MODAL.
criei para uma assim para sair do jframe
[quote]private void jButton5ActionPerformed(java.awt.event.ActionEvent evt) {
System.exit(0);
}[/quote]
e para minimizar
[quote]private void jButton_SairSair_Tela(java.awt.event.ActionEvent evt) {
setVisible(false);
dispose();
}[/quote]
