Boa noite pessoal,
Estou com o seguinte problema:
Criei uma tela Principal com clinete , produto e fornecedor.
Configurei cada item de menu para abrir a sua referidade tela de cadastro, tudo certinho e belezinha.
O problema em si é : eu consigo abrir todas as telas mas na hora de fechar a tela de fornecedores, quando eu clico pra fechar a tela principal está fechando simultaneamente.O que pode ser?
o que posso fazer pra corrigir isso?
Grato a todos,Abs!
Passe seu código que fica mais fácil…
Segue o codigo da tela principal e a de fornecedor

}Repare no método initComponents da classe Fornecedores.
O seguinte método está sendo utilizado para definir o que fazer quando fechar a Janela de Fornecedores:
setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE); Para que isto não ocorra, você deve fazer um tratamento personalizado para o evento de fechar a janela de Fornecedores.
Voce pode fazer o seguinte:
addWindowListener( new WindowAdapter() {
public void windowClosing( WindowEvent e ) {
// aqui apenas esta deixando o formulário invisível
Fornecedor.this.setVisible( false );
}
});Espero ter ajudado. Não sei se existe uma forma melhor para isso.
melhor do que simplesmente setar como visible(FALSE) é dar o dispose() da tela. Porque limpa da memória a aplicação fica mais leve.
