Como Fecho um JInternalFrame sem fechar a aplicação?[RESOLVIDO]

Assuntos Gerais
#1

Oi, pessoal tudo bem com vcs?

Estou desenvolvendo um aplicativo desktop para a minha loja. Tava tendo dificuldades para visualizar um JInternalFrame, mas graças a esse fórum consegui resolver o problema, só que agora eu não estou conseguindo fazer o JInternalFrame fechar. Tentei usar a variável closable do JInternalFrame, mas não deu resultado.

Depois setei o setDefaultCloseOperation para “Sair ao Fechar”. Mas também não deu resultado. Mas eu quero fazer isso sem ter que fechar o aplicativo. Será que alguém pode me ajudar?

Pronto aqui está o código.

  public class CadFuncionario extends javax.swing.JInternalFrame {

    /** Creates new form CadFuncionario */
    public CadFuncionario() {
        initComponents();
        setDefaultCloseOperation(EXIT_ON_CLOSE);
        
    }

    /** This method is called from within the constructor to
     * initialize the form.
     * WARNING: Do NOT modify this code. The content of this method is
     * always regenerated by the Form Editor.

Esse é o código do meu JInternalFrame. Como disse anteriormente, não estou conseguindo fechá-lo. A minha dúvida é como fechar um JInternalFrame sem fechar o form principal.

#4

Estou usando o método do próprio JInternalFrame closable para fechar o JInternalFrame, mas aí nada.
Será que alguém, sabe como proceder?

Olá amigo

tenta isso:

public class FramePrincipal extends JFrame implements ActionListener{

    static FramePatrimonio framePatrimonio;
.
.
.
.
    protected void createFramePatrimonio() throws PropertyVetoException, Exception {
        menu = menuBar;
        if (framePatrimonio == null) {
            framePatrimonio = new FramePatrimonio(this.dbConnection);
            framePatrimonio.setVisible(true); //necessary as of 1.3
            desktop.add(framePatrimonio);
            framePatrimonio.pack();
            desktop.getDesktopManager().maximizeFrame(framePatrimonio);
        } else {
            framePatrimonio.setVisible(true);
        }
        try {
            framePatrimonio.setSelected(true);
        } catch (java.beans.PropertyVetoException e) {
        }
        
    }


----: Aqui no frame patrimonio :----


public void jButtonFecharActionPerformed(java.awt.event.ActionEvent evt) {
      FecharForm();
}

public void FecharForm() {
     this.dispose();
     FramePrincipal.framePatrimonio = null;
 }

Qualquer coisa posta aí.

Caro Silvio Guedes.

Vi no seu exemplo que você usou um JFrame, para servir de exemplo. O que eu quero saber é o seguinte, como eu fecho um form do tipo JInternalFrame, sem ter que fechar toda a aplicação. É esse realmente o meu problema.

#7

Resolvi, obrigado a todos que postaram.

#8

Olá amigo

apenas postei a parte que interessava para sua dúvida, haja vista que, subentende-se o form principal sendo jFrame e o outro jInternalFrame.

veja que postei

 ----: Aqui no frame patrimonio :----  jInternalframe
   

 public class FramePatrimonio extends jInternalFrame {   <-------------seria isto que gostaria de ter visto.......

   
 public void jButtonFecharActionPerformed(java.awt.event.ActionEvent evt) {  
       FecharForm();  
 }  
   
 public void FecharForm() {  
      this.dispose();  
      FramePrincipal.framePatrimonio = null;  
 }

qualquer dúvida posta aí.
