Trying to draw image, but not showing up

[Mike Williams]

I am trying to get the lander image to appear on the Animation Panel when i run the program. The code in question is in class DrawPanel. For some reason image is not appearing. What could be wrong.

  
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.event.*;
 
public class Animation extends JFrame
{
    private DrawPanel AnimationPanel;
    private JPanel ButtonPanel;
    private JButton startButton, stopButton;
    
    public Animation()
    {
        super( "MoonLander" );
        // create animation area
        AnimationPanel = new DrawPanel();
        
        // set up start button
        startButton = new JButton( "Start" );
        startButton.addActionListener( new ActionListener()
        {
            public void actionPerformed( ActionEvent event )
            {
                // code to run animation
            }
        });
        
        // set up stop button
        stopButton = new JButton( "Stop" );
        stopButton.addActionListener( new ActionListener()
        {
            public void actionPerformed( ActionEvent event )
            {
                // code to stop animation
            }
        });
        
        // set up panel containing buttons
        ButtonPanel = new JPanel();
        //ButtonPanel.setLayout( new GridLayout() );
        ButtonPanel.add( startButton );
        ButtonPanel.add( stopButton );
        
        // attach button panel on content pane
        getContentPane().add( AnimationPanel, BorderLayout.CENTER );
        getContentPane().add( ButtonPanel, BorderLayout.SOUTH );
        
        
        setDefaultCloseOperation(EXIT_ON_CLOSE);
        setSize(350,350);
        setVisible(true);
    } 
    private class DrawPanel extends JPanel implements Runnable 
    {
        private Thread runner;
        int x = 175;
        int y = 175;
        Image lander = Toolkit.getDefaultToolkit().getImage( "lander.jpg" );
        Image landerFire = Toolkit.getDefaultToolkit().getImage( "landerfire.jpg" );

        public DrawPanel()
        {
            setBackground(Color.black);
        }
 
       public void paintComponent(Graphics g)
       {
           super.paintComponent(g);
           Graphics2D g2d = (Graphics2D)g;
           g2d.drawImage( lander, x, y, this );
       }
       public void run()
       {
       }
       
    }
       public static void main(String[] args)
       {
           new Animation();
       }
    
}

Can someone help me?

What is "code to draw animation" short for? If that's where you've placed the actual animation loop, then the problem is that you'lll be blocking the event thread, which is what actually repaints the screen; never do any long-running processing on the event thread! Instead, you have to create a new thread dedicated to running your animation.
The JDK demos include a number of animation applets; look there for examples.

I dont understand what your talkin about with the "code to draw animation" part, i dont see that, i just need that image to show up right now.

Ok I have went back and created 2 seperate classes, but it still does not show my image, can anyone help me?

  
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.event.*;
 
public class ImagePanel extends JPanel implements Runnable 
{
    
    private Thread runner;
    int x = getWidth();
    int y = getHeight();
    Image lander = Toolkit.getDefaultToolkit().getImage( "lander.jpg" );
    Image landerFire = Toolkit.getDefaultToolkit().getImage( "landerfire.jpg" );

    public ImagePanel()
    {
        setBackground(Color.black);
    }
   public void paintComponent(Graphics g)
   {
       super.paintComponent(g);
       Graphics2D g2d = (Graphics2D)g;
       g2d.drawImage( lander, x, y, this );
   }
   public void startAnimation()
   {
       runner = new Thread();
       
       if( runner == null ) 
       {
           runner = new Thread(this);
       }
       
       runner.start();
    }
   
   
    public void stopAnimation()
    {
      if  ( runner != null )
            runner = null;
    }
    
    public void run()
    {
    }
       
}

Please don't post questions to multiple forums. I just answered this for you over in the Threads forum, so I'm going to close this one; followups there, please.
