Duvidas com JtextFild

Programação Java
#1

Ola galera, estou programando no netbens.
Eu tenho 3 textfild.
Eu queria saber se tem como eu clicar em 1txt os outros 2txt ficassem ineditavel.

Se alguém puder me ajudar eu agradeceria muito.

#2

[i]Se n me engano existem um método setEditable

Coloca a tag resolvido no post pfvr, abc[/i]

#3

click com o botão direito encima do jTextField vá em Eventos depois em Mouse e depois click em MouseClicked para criar o Evento.
(botão direito > Eventos > MouseClicked )
e dentro do Evento coloque
o nome do jTextField que desabilitar mais .setEnabled(false);

vai fica mais ou menos assim

private void jTextField1MouseClicked(java.awt.event.MouseEvent evt) {
        jTextField2.setEnabled(false);
    }

Acho que ai desabilita o textfield, teria que ser : jTextField2.setEditable(false);

Bom vamos lá…

o primeiro exemplo funciona o seguinte:

quando o cara clicar no campo de texto 1, os outros 2 campos
ficarão desabilitados para edição.
Mas se ele clicar no campo 2 ou campo 3, ele poderá editar eles.

no caso eu fiz como você pediu:

exemplo 1:

[code]/*

    package Testes;

/**

    /**

      */
      public Teste() {
      initComponents();
      }

    /**

      @SuppressWarnings(“unchecked”)
      //
      private void initComponents() {

      jTextField1 = new javax.swing.JTextField();
      jTextField2 = new javax.swing.JTextField();
      jTextField3 = new javax.swing.JTextField();

      setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);

      jTextField1.setText(“jTextField1”);
      jTextField1.addMouseListener(new java.awt.event.MouseAdapter() {
      public void mouseClicked(java.awt.event.MouseEvent evt) {
      jTextField1MouseClicked(evt);
      }
      });

      jTextField2.setText(“jTextField2”);

      jTextField3.setText(“jTextField3”);

      javax.swing.GroupLayout layout = new javax.swing.GroupLayout(getContentPane());
      getContentPane().setLayout(layout);
      layout.setHorizontalGroup(

        break;
        }
        }
        } catch (ClassNotFoundException ex) {

        //

      /* Create and display the form */
      java.awt.EventQueue.invokeLater(new Runnable() {
      public void run() {
      new Teste().setVisible(true);
      }
      });
      }
      // Variables declaration - do not modify
      private javax.swing.JTextField jTextField1;
      private javax.swing.JTextField jTextField2;
      private javax.swing.JTextField jTextField3;
      // End of variables declaration
      }
      [/code]

No exemplo 2 ele bloqueia os campos, é bem parecido com o exemplo 1
deixei nesse exemplo 2, um campo desabilitado para edição e outro campo
desabilitado como componente, assim esse último fica mais escuro

observa aí:
