CardLayout - hvilken metode?

Prøv denne her:

((CardLayout) parent.getLayout()).show(parent, \"name\");

Hm, jeg får en \"method.getLayout() not found in class java.awt.CardLayout\" fejl.

Ok. I mit eksempel er \"parent\" et JPanel, hvor layout er sat til cardlayout. Parent er ikke en instans af CardLayout. Hjælper det dig ?

Jeg er ikke helt sikker. Her er min kildekode: (lavet med JDeveloper, så den er garanteret ikke den mest effektive)


package package1;

import javax.swing.*;
import java.awt.*;
import oracle.dacf.control.swing.*;
import oracle.jdeveloper.layout.*;
import oracle.dacf.layout.*;
import java.awt.event.*;

public class frame1 extends JFrame {
  JPanel jPanel1 = new JPanel();
  CardLayout cardLayout1 = new CardLayout();
  JLabel jLabel2 = new JLabel();
  XYLayout xYLayout2 = new XYLayout();
  JLabel jLabel1 = new JLabel();
  JPanel jPanel2 = new JPanel();
  XYLayout xYLayout1 = new XYLayout();
  JLabel jLabel3 = new JLabel();
  JPasswordField jPasswordField1 = new JPasswordField();
  JTextField jTextField1 = new JTextField();
  JButton jButton1 = new JButton();
  JButton jButton2 = new JButton();
  JPanel jPanel3 = new JPanel();
  XYLayout xYLayout3 = new XYLayout();
  JButton jButton3 = new JButton();
  JButton jButton4 = new JButton();
  JButton jButton5 = new JButton();

  /**
  * Constructs a new instance.
  */
  public frame1() {
    super();
    try  {
      jbInit();
    }
    catch (Exception e) {
      e.printStackTrace();
    }
  }

  /**
  * Initializes the state of this instance.
  */
  private void jbInit() throws Exception {
    this.getContentPane().setLayout(xYLayout2);
    this.setSize(new Dimension(424, 425));
    jLabel2.setText(\"CPR\");
    jLabel1.setFont(new Font(\"Dialog\", 0, 18));
    jLabel3.setText(\"Kode\");
    jLabel3.setFont(new Font(\"Dialog\", 0, 18));
    jButton1.setText(\"Log ind\");
    jButton1.addActionListener(new java.awt.event.ActionListener() {

      public void actionPerformed(ActionEvent e) {
        jButton1_actionPerformed(e);
      }
    });
    jButton2.setText(\"Afslut\");
    jButton3.setText(\"Fastansat\");
    jButton4.setText(\"Institutleder\");
    jButton5.setText(\"Lønanviser\");
    jPanel3.setLayout(xYLayout3);
    jPanel2.setLayout(xYLayout1);
    jLabel1.setText(\"CPR\");
    jPanel1.setLayout(cardLayout1);
    this.setTitle(\"Over-/merarbejde\");
    this.getContentPane().add(jPanel1, new XYConstraints(0, 15, -1, 383));
    jPanel1.add(jPanel2, \"jPanel2\");
    jPanel2.add(jLabel1, new XYConstraints(27, 13, 66, -1));
    jPanel2.add(jLabel3, new XYConstraints(26, 61, -1, -1));
    jPanel2.add(jPasswordField1, new XYConstraints(27, 85, 141, -1));
    jPanel2.add(jTextField1, new XYConstraints(25, 36, 143, -1));
    jPanel2.add(jButton1, new XYConstraints(66, 117, -1, -1));
    jPanel1.add(jPanel3, \"jPanel3\");
    jPanel3.add(jButton3, new XYConstraints(65, 27, -1, -1));
    jPanel3.add(jButton4, new XYConstraints(60, 54, -1, -1));
    jPanel3.add(jButton5, new XYConstraints(62, 81, -1, -1));
    this.getContentPane().add(jButton2, new XYConstraints(346, 4, -1, -1));
  }

  void jButton1_actionPerformed(ActionEvent e) {
    ((CardLayout) cardLayout1.getLayout()).show(cardLayout1, \"jPanel3\");


  }
}

Jeg fandt selv ud af det. Dum lille fejl ;)

Men tak for hjælpen. :)
