Hi,
I have a JPanel with a cardLayout, however when i try to go to the next card nothing happens. Here is my code:
01 import java.applet.*; 02 import java.awt.*; 03 import java.util.*; 04 import java.awt.event.*; 05 import javax.swing.JEditorPane; 06 import javax.swing.*; 07 public class FindAddApplet extends Applet implements ActionListener 08 { 09 private JLabel jcomp1; 10 private JButton nextButton; 11 private JButton prevButton; 12 private JPanel contentPanel; 13 //content layout 14 private CardLayout cardLayout; 15 //jpanel cards 16 ClassYearCard classYear; 17 PeriodCard periodCard; 18 //labels for cards 19 private int currentLabel = 0; 20 String classYearLabel = ("card1"); 21 String periodCardLabel = ("card2"); 22 23 public void init() { 24 //construct components 25 cardLayout = new CardLayout(); 26 jcomp1 = new JLabel ("Main Page"); 27 nextButton = new JButton ("Next >"); 28 prevButton = new JButton ("< Previous"); 29 contentPanel = new JPanel (); 30 classYear = new ClassYearCard(); 31 periodCard = new PeriodCard(); 32 33 //adjust size and set layout 34 setPreferredSize (new Dimension (415, 414)); 35 setLayout (null); 36 37 //add components 38 add (jcomp1); 39 add (nextButton); 40 nextButton.addActionListener(this); 41 add (prevButton); 42 add (contentPanel); 43 contentPanel.setLayout(cardLayout); //sets layout of contentPanel 44 45 //set content layout 46 47 //add stuff to panel 48 contentPanel.add(classYear, classYearLabel); 49 contentPanel.add(periodCard, periodCardLabel); 50 51 //set component bounds (only needed by Absolute Positioning) 52 jcomp1.setBounds (25, 5, 100, 25); 53 nextButton.setBounds (295, 375, 110, 25); 54 prevButton.setBounds (175, 375, 110, 25); 55 contentPanel.setBounds (15, 30, 390, 340); 56 } 57 58 public void start() { 59 } 60 61 public void actionPerformed(ActionEvent e){ 62 if (e.getSource() == "nextButton"){ 63 cardLayout.show(contentPanel, "card2"); 64 } 65 } 66 67 public void stop() { 68 } 69 70 public void destroy() { 71 } 72 73 }
When i click the next button the panel just stays what it is currently, do i need to do something like repaint the contentPanel?
Thanks,
