    <p>For comparison, I've re-factored @HFOE's <a href="https://stackoverflow.com/a/11553472/230513">example</a> so that <code>Ground implements Icon</code> and indexes the array returned by <code>values()</code>. As <code>value</code> is an implementation detail, <code>int[][] MAP</code> could instead be <code>Ground[][] MAP</code>.</p> <p>Update: This variation illustrates <code>Ground[][] MAP</code> and adds <code>TexturePaint</code>.</p> <p><img src="https://i.stack.imgur.com/GAUpA.png" alt="enter image description here"></p> <pre><code>import java.awt.Color; import java.awt.Component; import java.awt.Graphics; import java.awt.Graphics2D; import java.awt.GridLayout; import java.awt.TexturePaint; import java.awt.geom.Rectangle2D; import java.awt.image.BufferedImage; import java.util.Random; import javax.swing.*; /** @see https://stackoverflow.com/a/11556441/230513 */ public class GridExample extends JPanel { public static final Ground[][] MAP = { {Ground.GRASS, Ground.GRASS, Ground.DIRT, Ground.WATER, Ground.WATER}, {Ground.GRASS, Ground.DIRT, Ground.CITY, Ground.WATER, Ground.WATER}, {Ground.GRASS, Ground.DIRT, Ground.CITY, Ground.WATER, Ground.WATER}, {Ground.GRASS, Ground.DIRT, Ground.DIRT, Ground.DIRT, Ground.WATER}, {Ground.GRASS, Ground.GRASS, Ground.DIRT, Ground.WATER, Ground.WATER}, }; private JLabel[][] labelGrid = new JLabel[MAP.length][MAP[0].length]; public GridExample() { setLayout(new GridLayout(MAP.length, MAP[0].length)); for (int r = 0; r &lt; labelGrid.length; r++) { for (int c = 0; c &lt; labelGrid[r].length; c++) { labelGrid[r][c] = new JLabel(); labelGrid[r][c].setIcon(MAP[r][c]); add(labelGrid[r][c]); } } } private static void createAndShowGui() { GridExample mainPanel = new GridExample(); JFrame frame = new JFrame("GridExample"); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.add(mainPanel); frame.pack(); frame.setLocationByPlatform(true); frame.setVisible(true); } public static void main(String[] args) { SwingUtilities.invokeLater(new Runnable() { @Override public void run() { createAndShowGui(); } }); } } enum Ground implements Icon { DIRT(new Color(205, 133, 63)), GRASS(new Color(0, 107, 60)), WATER(new Color(29, 172, 214)), CITY(Color.lightGray); private static final int SIZE = 42; private Random random = new Random(); private TexturePaint paint; private Ground(Color color) { this.paint = initPaint(color); } private TexturePaint initPaint(Color color) { BufferedImage image = new BufferedImage( SIZE, SIZE, BufferedImage.TYPE_INT_ARGB); Rectangle2D.Double rect = new Rectangle2D.Double(0, 0, SIZE, SIZE); for (int row = 0; row &lt; SIZE; row++) { for (int col = 0; col &lt; SIZE; col++) { if (random.nextBoolean()) { image.setRGB(col, row, color.getRGB()); } else { if (random.nextBoolean()) { image.setRGB(col, row, color.darker().getRGB()); } else { image.setRGB(col, row, color.brighter().getRGB()); } } } } return new TexturePaint(image, rect); } @Override public void paintIcon(Component c, Graphics g, int x, int y) { Graphics2D g2d = (Graphics2D) g; g2d.setPaint(paint); g.fillRect(0, 0, SIZE, SIZE); } @Override public int getIconWidth() { return SIZE; } @Override public int getIconHeight() { return SIZE; } } </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.
