    <p>I'm using java trying to make a basic game but am having some trouble with a KeyAdapter. I've used a very similar format before and thought I understood it, but this has me stumped.</p> <p>Any help would be appreciated, here is the main code I'm working with</p> <pre><code>public class Board extends JPanel implements ActionListener{ Timer timer; Tank tank = new Tank(); boolean boardset; public Board(){ setBackground(Color.BLACK); ImageIcon alien1ii = new ImageIcon(this.getClass().getResource("si_Alien1.png")); Image alien1 = alien1ii.getImage(); ImageIcon alien2ii = new ImageIcon(this.getClass().getResource("si_Alien2.png")); Image alien2 = alien2ii.getImage(); ImageIcon alien3ii = new ImageIcon(this.getClass().getResource("si_Alien3.png")); Image alien3 = alien3ii.getImage(); timer = new Timer(5, this); timer.start(); addKeyListener(new TAdapter()); JButton button = new JButton(new AbstractAction("hello2"){ @Override public void actionPerformed(ActionEvent e){ boardset = false; } }); this.add(button); //actual game setFocusable(true); setDoubleBuffered(true); } public void paint(Graphics g){ super.paint(g); g.setColor(Color.WHITE); Graphics2D g2d = (Graphics2D) g; g2d.drawImage(tank.getTank(), tank.getx(), tank.getY(), this); g2d.drawLine(0, (tank.getY()+25), 400, (tank.getY()+25)); Toolkit.getDefaultToolkit().sync(); g.dispose(); } public class TAdapter extends KeyAdapter{ public void keyPressed(KeyEvent e){ tank.keyPressed(e); System.out.println("pressedddddddddddddddddd"); } public void keyReleased(KeyEvent e){ tank.keyReleased(e); } } public void setBoardset(boolean x){ boardset = x; } public boolean getBoardset(){ return boardset; } @Override public void actionPerformed(ActionEvent e) { repaint(); tank.move(); } } </code></pre> <p>Seems to me like this should be pretty straightforward, right now I'm using this print statement to see if the class is actually recognizing key strokes at all: public class TAdapter extends KeyAdapter{ public void keyPressed(KeyEvent e){ tank.keyPressed(e); System.out.println("pressedddddddddddddddddd"); }</p> <p>However, there is no output. So I suspect it is not recognizing any keystrokes at all. But I can't figure out why. If anybody has any suggestions I would appreciate it. Obviously I have more code I can share if anybody thinks it would be useful in figuring out this bug.</p>

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.
