    <p>You need to add the respective key to the <code>InputMap</code> of the component on which to apply <code>KeyBinding</code> as shown here : </p> <pre><code>panel.getInputMap(JComponent.WHEN_IN_FOCUSED_WINDOW).put( KeyStroke.getKeyStroke("pressed UP"), "pressedUPAction"); panel.getInputMap(JComponent.WHEN_IN_FOCUSED_WINDOW).put( KeyStroke.getKeyStroke("released UP"), "releasedUPAction"); panel.getActionMap().put("pressedUPAction", new AbstractAction() { @Override public void actionPerformed(ActionEvent ae) { System.out.println("UP Arrow Pressed"); } }); panel.getActionMap().put("releasedUPAction", new AbstractAction() { @Override public void actionPerformed(ActionEvent ae) { System.out.println("UP Arrow Released"); } }); </code></pre> <p>Have a look at this working example :</p> <pre><code>import java.awt.*; import java.awt.event.*; import javax.swing.*; public class SmallExample { private JButton button; private JPanel panel; private void displayGUI() { JFrame frame = new JFrame("Small Example"); frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE); panel = new JPanel() { @Override public Dimension getPreferredSize() { return (new Dimension(100, 100)); } }; panel.getInputMap(JComponent.WHEN_IN_FOCUSED_WINDOW).put( KeyStroke.getKeyStroke("pressed UP"), "pressedUPAction"); panel.getInputMap(JComponent.WHEN_IN_FOCUSED_WINDOW).put( KeyStroke.getKeyStroke("released UP"), "releasedUPAction"); panel.getActionMap().put("pressedUPAction", new AbstractAction() { @Override public void actionPerformed(ActionEvent ae) { System.out.println("UP Arrow Pressed"); } }); panel.getActionMap().put("releasedUPAction", new AbstractAction() { @Override public void actionPerformed(ActionEvent ae) { System.out.println("UP Arrow Released"); } }); frame.setContentPane(panel); frame.pack(); frame.setLocationByPlatform(true); frame.setVisible(true); } public static void main(String[] args) { Runnable runnable = new Runnable() { @Override public void run() { new SmallExample().displayGUI(); } }; EventQueue.invokeLater(runnable); } } </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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
