Boa noite pessoal. Alguém pode me dar uma mão neste código do Deitel, cap 31. O botão não executa ação nenhuma…


package welcomesoapclient;

import welcome.WelcomeSOAP;
import welcome.WelcomeSOAPService;
import javax.swing.JOptionPane;

public class WelcomeSOAPClientJFrame extends javax.swing.JFrame {

    private WelcomeSOAP welcomeSOAPProxy;

    /** Creates new form WelcomeSOAPClientJFrame */
    public WelcomeSOAPClientJFrame() {
        initComponents();

        try {
            WelcomeSOAPService service = new WelcomeSOAPService();
            welcomeSOAPProxy = service.getWelcomeSOAPPort();
            System.out.println("try");
        } catch (Exception exception){
            exception.printStackTrace();
            System.exit(1);
        }
    }

    
    @SuppressWarnings("unchecked")

        setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);

        nameJLabel.setText("Nome:");

        submitJButton.setText("Submit");
        submitJButton.addKeyListener(new java.awt.event.KeyAdapter() {

                submitJButtonActionPerformed(evt);

Você já tentou digitar qualquer caractere do teclado quando o foco está no botão?

#3

Entenda a interface KeyListener

Esta interface é usada para receber eventos do teclado (pressionamento de teclas). Classes interessadas em processar eventos do teclado devem implementar esta interface (e todos os seus métodos) ou extender a classe abstrata KeyAdapter (sobrescrevendo apenas os métodos de interesse).
