Hi friend,

i am sending simple program of using CardLayout Manager.


import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.*;
import javax.swing.BorderFactory;
import javax.swing.BoxLayout;
import javax.swing.ButtonGroup;
import javax.swing.JComponent;
import javax.swing.JRadioButton;

public class CardlayoutTest implements ActionListener {
JPanel cards;
final static String[] strings =
{"Welcome", "Welcome To Java Tutorial",
"Welcome Roseindia"};

private static JComponent createComponent(String s) {
JLabel l = new JLabel(s);
l.setBorder(BorderFactory.createMatteBorder(5,5,5,5, Color.DARK_GRAY));
l.setHorizontalAlignment(JLabel.CENTER);
return l;
}

public void addCardsToPane(Container pane) {
JRadioButton[] rb = new JRadioButton[strings.length];
ButtonGroup group = new ButtonGroup();
JPanel buttons = new JPanel();
buttons.setLayout(new BoxLayout(buttons, BoxLayout.PAGE_AXIS));

for (int i= 0; i < strings.length; i++) {
rb[i] = new JRadioButton("Display Component" + (i+1));
rb[i].setActionCommand(String.valueOf(i));
rb[i].addActionListener(this);
group.add(rb[i]);
buttons.add(rb[i]);
}
rb[0].setSelected(true);

cards = new JPanel(new CardLayout());
for (int i = 0; i < strings.length; i++) {
cards.add(createComponent(strings[i]), String.valueOf(i));
}

pane.add(buttons, BorderLayout.NORTH);
pane.add(cards, BorderLayout.CENTER);
}

public void actionPerformed(ActionEvent evt) {
CardLayout cl = (CardLayout)(cards.getLayout());
cl.show(cards, (String)evt.getActionCommand());
}

public static void main(String[] args) {
JFrame.setDefaultLookAndFeelDecorated(true);

JFrame frame = new JFrame();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

CardlayoutTest card = new CardlayoutTest();
card.addCardsToPane(frame.getContentPane());
frame.setSize(300, 250);
frame.setVisible(true);
}
}
