public class CardExample
extends java.lang.Object

An example to illustrate the use of the class CardCell for the GUI shown below.

The GUI contains a CardCell at the bottom. The CardCell has three JLabel objects as its elements, with their display texts being Mutable Component 1, Mutable Component 2, and Mutable Component 3. When the user clicks the button with text Show Component 2, the label with the text Mutable Component 2 in the card is displayed. The the other buttons are associated with the labels in a similar fashion.

public class CardExample
{
        public static String MUTABLECELLNAME="Mutable Component ";
        public static void createGUI()
        {
                // Create the card with the three labels.
                CardCell card=new CardCell();
                for(int i=1;i<=3;i++)
                {
                        String name=MUTABLECELLNAME+i;
                        card.add(name,namedPanel(name));
                }
                JFrame f=new JFrame();
                // The top level cell.
                ButtonGroup bg=new ButtonGroup();
                // Create the three buttons with appropriate action listeners.
                JRadioButton buttons[]=new JRadioButton[3];
