setBackground().. and Cusor()

[Justin Fox]

ok can you change the color of the CROSSHAIR_CUSOR?

and in this code, the setBackground method isnt working...

    
 
import java.awt.Event.*;
import java.awt.*;
import javax.swing.*;
 

public class BattleShip extends JPanel
{
 
JButton connect, startGame, chat;
Cursor mycursor;
 
public BattleShip()
{
setBackground(Color.cyan);
mycursor = new Cursor(Cursor.CROSSHAIR_CURSOR);
setCursor(mycursor);
 

setLayout(new FlowLayout());
 
connect = new JButton("Connect");
startGame = new JButton("Start");
chat = new JButton("Chat");
 
add(connect);
add(startGame);
add(chat);
 

setPreferredSize(new Dimension(600,300));
 

 
}
public void paintComponent(Graphics g)
{
int Xoriginal = 40;
int Yoriginal = 40;
int count = 0;

int X = Xoriginal;
int Y = Yoriginal;
 
int W = 20;
int L = 20;
 

  for(int i = 0; i< 100; i++)
  {
g.setColor(Color.black);
g.drawRect(X,Y,W,L);
g.setColor(Color.gray);
g.fillRect(X+1,Y+1,W-1,L-1);

count ++;
X += W;

if(count == 10)
{
X = Xoriginal;
Y += L;
count = 0;
}
  }
 
count = 0;
int Xoriginal2 = 320;


X = Xoriginal2;
Y = Yoriginal; 
 
  for(int i = 0; i< 100; i++)
  {
g.setColor(Color.black);
g.drawRect(X,Y,W,L);
g.setColor(Color.gray);
g.fillRect(X+1,Y+1,W-1,L-1);
count ++;
X+=W;
 
if(count == 10)
{
X = Xoriginal2;
Y +=L;
count = 0;
}
  }
 



}
 
}
 

 

here is the JFrame()...

    
 
import javax.swing.JFrame;
 

public class BattleShipFrame extends JFrame
{
public static void main (String[]args)
{
 
JFrame fram = new JFrame("BattleShip");
fram.setDefaultCloseOperation(EXIT_ON_CLOSE);
 
fram.getContentPane().add(new BattleShip());
 
fram.pack();
fram.setVisible(true);
 
}
}

thanks,

Justin

About the background color.
The parent is responsible for repainting the background but as you are overriding paintComponent, the backgound won't be repainted. You've got to call super.paintComponent(g).
