CardLayout – Java Swing – Example

In this tutorial, we are going to see an example of CardLayout in Java Swing. CardLayout class manages components in such a way that only one component is visible at a time. It treats each component as a card, which is why it is called CardLayout.

The constructors of CardLayout class are:

CardLayout Constructors	Description
CardLayout()	Arrange the components as a card without horizontal and vertical space.
CardLayout(int h, int v)	Arrange the components as a card with the given horizontal and vertical space.

 

 
Commonly used methods of CardLayout are the following:

• public void next(Container parent): is used to return to the next card in the given container.
• public void previous(Container parent): is used to return to the previous card of the given container.
• public void first(Container parent): is used to return to the first card of the given container.
• public void last(Container parent): is used to return to the last card of the given container.
• public void show(Container parent, String name): is used to return to the specified card with the given name.

public class MyCardLayout extends JFrame implements ActionListener
{
  CardLayout card;
  Container c;
  
  MyCardLayout()
  {  
    c = getContentPane();
    //create a CardLayout object with 30 hor spaces and 20 ver spaces
    card = new CardLayout(30,20);
    c.setLayout(card);
    
    JButton btn1 = new JButton("Welcome");
    JButton btn2 = new JButton("To");
    JButton btn3 = new JButton("StackHowTo");
    
    btn1.addActionListener(this);
    btn2.addActionListener(this);
    btn3.addActionListener(this);
      
    c.add("a",btn1);c.add("b",btn2);c.add("c",btn3);
            
  }
  public void actionPerformed(ActionEvent e) {
    card.next(c);
  }

  public static void main(String[] args) {
    MyCardLayout frame = new MyCardLayout();
    frame.setSize(300,300);
    frame.setVisible(true);
    frame.setDefaultCloseOperation(EXIT_ON_CLOSE);
