    <p>I need some help on my java code I'm a newbie in java, What I want to do is once I press a letter I want to display some message just to verify that the code works. Using javax swing library specifically the keylistener and key event and I don't know if I'm doing it right. here are my code:</p> <pre><code>import java.awt.*; import javax.swing.*; import java.awt.event.*; import java.awt.event.KeyListener; import java.awt.event.KeyEvent; public class KeyStrokeButton{ public JFrame frame; public JPanel panel; public JButton btnfocus, btnrelease, btnwindow, btnancestor; public JTextField text; public static void main(String[] args) { SwingUtilities.invokeLater(new Runnable(){ public void run() { KeyStrokeButton mydesign = new KeyStrokeButton(); mydesign.design(); } }); } public void design() { panel = new JPanel(); panel.setLayout(null); frame = new JFrame("Keystroke Tutorials"); frame.getContentPane().add(panel); frame.setSize(250, 250); frame.setVisible(true); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); btnfocus = new JButton("&lt;html&gt;&lt;center&gt;Focus"); btnfocus.setBounds(10, 10, 90, 80); panel.add(btnfocus); btnfocus.addKeyListener(new ClickPressed()); btnrelease = new JButton("Release"); btnrelease.setBounds(110, 10, 90, 80); panel.add(btnrelease); btnancestor = new JButton("Ancestor"); btnancestor.setBounds(10, 100, 90, 80); panel.add(btnancestor); btnwindow = new JButton("Window"); btnwindow.setBounds(110, 100, 90, 80); panel.add(btnwindow); } class ClickPressed implements KeyListener { public void KeyPressed(KeyEvent e) { //any code. } } } </code></pre> <p>as much as possible I want to separate my code for the event, so I create a class to make it readable.</p>

    3. COI don't think you want to use KeyListener for buttons. You might want to consider adding ActionListeners to your buttons via the addActionListener method.

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.

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