    <p>The game I'm trying to create is snake and so far I've figured out how to use <code>paint(Graphics g)</code> a bit of <code>JPanel</code>, mouse listener and now I'm trying to create a rectangle that will move across the screen and use key bindings or key listener, but I have no idea how I should go about this.</p> <p>Here's my code so far, it has 2 parts. The first part is called <code>snake2</code> because if I don't know what I'm doing I make the same program with different things. <code>Snake</code> used frame, but <code>Snake2</code> uses <code>JPanel</code> (looks better…)</p> <pre><code> import java.awt.*; //required for MouseListener import java.awt.event.*; //requied for Graohics import java.applet.*; import javax.swing.*; public class Snake2 extends JPanel { private Rectangle sampleObject; public Snake2() { addMouseListener(new MouseListener()); } /* create background */ public void paint (Graphics g) { Font angel = new Font("Angelic War", Font.BOLD, 60); Font ith = new Font("Ithornît", Font.BOLD, 78); setBackground(Color.darkGray); g.setColor(Color.darkGray); g.fillRect(0,0,700,850); g.setColor(Color.gray); g.fillRect(50,150,600,650); g.setColor(Color.white); g.drawRect(50,150,600,650); g.drawString("Quit",52,116); g.drawRect(50,100,30,20); //g.setFont(angel); //g.drawString("SNAKE",300,70); g.setFont(ith); g.drawString("SNAKE",280,90); } public void sprite (int x, int y, Graphics g){ g.setColor(Color.white); g.fillRect(300,200,10,10); } public void start (int x, int y, Graphics g){ g.setColor(Color.white); g.drawString("START GAME",300,425); } } /* Tracks where mouse is clicked */ class MouseListener extends MouseAdapter { public void mouseReleased(MouseEvent me) { if (me.getX() &gt;= 50 &amp;&amp; me.getX() &lt;= 80 &amp;&amp; me.getY() &gt;= 100 &amp;&amp; me.getY() &lt;= 120) { System.exit(0); } String str="Mouse Released at "+me.getX()+","+me.getY(); System.out.println(str); } } </code></pre> <p>And the second part is:</p> <pre><code> import javax.swing.JFrame; import java.awt.Dimension; public class SnakeDisplay { public static void main ( String [ ] arguments ) { JFrame frame = new JFrame ( "Snake" ); Snake2 panel = new Snake2 ( ); frame.setDefaultCloseOperation ( JFrame.EXIT_ON_CLOSE ); frame.add ( panel ); frame.setContentPane ( panel ); frame.setPreferredSize ( new Dimension ( 700, 850 ) ); //frame.setLocationRelativeTo ( null ); frame.setVisible ( true ); frame.pack ( ); } } </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.
