Fechar a tela no NetBeans

2 respostas

Caros amigos!

Estou desenvolvendo um sisteminha com três classes no NetBeans 5.0:
main.java, CadCliente.java e ConCliente.java

O proceso correto que devo fazer é:

‘main’ chama CadCliente ( que cadastro o cliente ) que por sua vez, chama ConCliente através do botão btconsultar.

o problema é que quando fecho a Tela ConCliente a CadCliente tb fecha.
Deveria fechar somente a ConCliente. E deixar a CadCliente ainda aberta.
O que está faltando?
Qual a melhor forma de chamar uma JFrame. Vcs poderiam me ajudar?
Agradeço imensamente a todos!

Seguem as classes abaixo>

Esta é a main.java:

[b]package sisdados;

import java.awt.event.WindowAdapter;

import java.awt.event.WindowEvent;

import java.awt.event.WindowListener;

public class Main extends CadCliente{

public Main() {
    
}

public static void main(String[] args) {

CadCliente cadcliente = new CadCliente();

cadcliente.show();

WindowListener x = new WindowAdapter(){

public void windowClosing(WindowEvent e){

System.exit(0);

}

};

cadcliente.addWindowListener(x);		

}

}[/b]

Esta é a classe CadCliente.java:

[b]package sisdados;

import java.awt.Font;

import java.awt.event.ActionEvent;

import java.awt.event.ActionListener;

import java.awt.event.WindowAdapter;

import java.awt.event.WindowEvent;

import java.awt.event.WindowListener;

public class CadCliente extends javax.swing.JFrame implements ActionListener{

public CadCliente() {
    initComponents();
    setLocation(240,100);setResizable(false);
    btconsultar.addActionListener(this);        
}
