    <p>I looked at a code example that used this code:</p> <pre><code>cl.show(cardPanel, "" + (currentCard)); </code></pre> <p>But when I use <code>show</code> I get a message in Eclipse that it's deprecated and I wonder if there is another way to show the different cards in the CardLayout when I click on the buttons? Below is the code for my CardLayout class. Suggestions are also welcome if some part of the code are bad practise. Thanks!</p> <pre><code>import java.awt.*; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import javax.swing.*; public class CardLayoutTest extends JFrame implements ActionListener { // Ref private JPanel cardPanel, jp1, jp2, buttonPanel; private JLabel jl1, jl2; private JButton btn1, btn2; private CardLayout cardLayout; // Konstruktor public CardLayoutTest() { setTitle("Test med CardLayout"); setSize(600,400); cardPanel = new JPanel(); buttonPanel = new JPanel(); cardPanel.setLayout(cardLayout); jp1 = new JPanel(); jp2 = new JPanel(); jl1 = new JLabel("Card 1"); jl2 = new JLabel("Card 2"); jp1.add(jl1); jp2.add(jl2); cardPanel.add(jp1, "1"); cardPanel.add(jp2, "2"); btn1 = new JButton("Show Card 1"); btn2 = new JButton("Show Card 2"); buttonPanel.add(btn1); buttonPanel.add(btn2); getContentPane().add(cardPanel, BorderLayout.NORTH); getContentPane().add(buttonPanel, BorderLayout.SOUTH); btn1.addActionListener(this); } public void actionPerformed(ActionEvent event) { // ??? Show card 1 ??? // ??? Show card 2 ??? } public static void main(String[] args) { CardLayoutTest frame = new CardLayoutTest(); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setVisible(true); } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
