jDialog do not dispose

Question

我有一个jFrame，当我按F2调用jDialog时，在这个jDialog中放入一些信息，然后当按下或单击jButton或Enter时，我得到信息并处理jDialog。

然而，jDialog并没有关闭，而是获取了我请求的所有信息。

这是代码：

/**
* Creates new form DialogCPF
*/
public DialogCPF(java.awt.Frame parent, boolean modal) {
super(parent, modal);
initComponents();
jFormattedTextField1.addKeyListener(new Tecla() {
@Override
public void keyReleased(KeyEvent e) {

}
});
}
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {                                         
// TODO add your handling code here:

ConsumirWS2 WS = new ConsumirWS2();
try {
WS.Buscar();
} catch (Exception ex) {
Logger.getLogger(DialogCPF.class.getName()).log(Level.SEVERE, null, ex);
}
jButtonSalvar.setEnabled(true);
jButtonExcluir.setEnabled(false);
jButtonINSERIR.setEnabled(false);
jButtonALTERAR.setEnabled(false);
jButtonPROCURAR.setEnabled(false);
jTextFieldAPELIDO.setEnabled(true);
jTextFieldNOME.setEnabled(true);
jFormattedTextFieldCPF.setEnabled(true);
jFormattedTextFieldDATA.setEnabled(true);
jTextFieldID.setEnabled(false);
/*DialogCPF dialog = new DialogCPF(new javax.swing.JFrame(), false);
dialog.dispose();*/
DialogCPF A = (DialogCPF)evt.getSource();
A.dispose();

}

}
});

dialog.addKeyListener(new KeyListener(){

@Override
public void keyPressed(KeyEvent e) {

@Override
public void keyReleased(KeyEvent e) {

DialogCPF dialog = new DialogCPF(new javax.swing.JFrame(), true);
//dialog.setEnabled(false);
dialog.dispose();
}
}
});        
dialog.setVisible(true);
}
});
}
// Variables declaration - do not modify                     
private javax.swing.JButton jButton1;
public static javax.swing.JFormattedTextField jFormattedTextField1;
private javax.swing.JLabel jLabel1;
public javax.swing.JLabel jLabel2;
private javax.swing.JPanel jPanel1;
// End of variables declaration                   
}

我已经尝试过这个，这个和这个解决方案，然而，我无法带来解决方案

Answer 1

这个。。。

private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
// TODO add your handling code here:
ConsumirWS2 WS = new ConsumirWS2();
try {
WS.Buscar();
} catch (Exception ex) {
Logger.getLogger(DialogCPF.class.getName()).log(Level.SEVERE, null, ex);
}
//...
DialogCPF A = (DialogCPF) evt.getSource();
A.dispose();
}

不太可能工作，因为ActionEvent的来源不太可能是对话框。我还关心ConsumirWS2实例的创建，这不是对话框的责任，对话框应该允许调用方提取它需要的信息，可能是通过观察者模式。

这个。。。

dialog.addKeyListener(new KeyListener() {
@Override
public void keyTyped(KeyEvent e) {
// Nothing
}
@Override
public void keyPressed(KeyEvent e) {
// Nothing 
}
@Override
public void keyReleased(KeyEvent e) {
if (e.getKeyCode() == KeyEvent.VK_ENTER) {
//...
}
}
});

这是一个坏主意，原因有很多，除了对用户来说不明显之外，任何将焦点从对话框中移开的组件(如文本字段(都会阻止它的执行。相反，请参阅如何将Java默认按钮设置为对ENTER键_released_作出反应？获得更好的解决方案

但当我们在这里的时候。。。

@Override
public void keyReleased(KeyEvent e) {
if (e.getKeyCode() == KeyEvent.VK_ENTER) {
//...
DialogCPF dialog = new DialogCPF(new javax.swing.JFrame(), true);
//dialog.setEnabled(false);
dialog.dispose();
}
}

不起作用。您创建一个对话框的新实例并立即处理它。。。这将如何影响屏幕上触发此事件的对话框实例？！

一般来说，你需要在对话框的当前实例上调用dispose，你最好看看如何制作对话框和如何制作框架，当然你最好避免使用表单编辑器
