Hey,
Guys and gulls i need help with the following asap.
I'm trying to code a checkers board in java and populate it with checkers and then paint this onto a JPanel. I then add the JPanel to my JFrame.
I am able to draw my checkers board and populate it with checkers. I do this by creating a class which extends JPanel. I then use the paint method to draw my board and checkers and then paint this onto the JPanal. I then have another class which creates the JFrame and adds the JPanel to it. However whenever I add the JPanel to the JFrame, the JPanel wont size to the size I set it at.
Below is my code. This one has really been racking my brains so help would greatly be appreciated.
Cheers
import java.awt.*;
import javax.swing.*;
public class Board extends JPanel
{
public Board()
{
this.setSize(200, 200);
}
public void paint(Graphics g)
{
super.paint(g);
int row;
int col;
int x,y;
String type = "";
for ( row = 1; row < 9; row++ )
{
for ( col = 1; col < 9; col++)
{
x=col * 50;
y=row * 50;
if ( (row % 2) == (col % 2) )
{
g.setColor(Color.WHITE);
type = "white";
}
else
{
g.setColor(Color.BLACK);
type = "black";
}
g.fillRect(x, y, 50, 50);
g.setColor(Color.RED);
if (type == "black" && (row==1 || row ==2 || row==3))
{
g.drawOval(x+5, y+5, 40, 40);
g.fillOval(x+5, y+5, 40, 40);
}
else if (type == "black" && (row==6 || row ==7 || row==8))
{
g.setColor(Color.BLUE);
g.drawOval(x+5, y+5, 40, 40);
g.fillOval(x+5, y+5, 40, 40);
}
}
}
}
}
import java.awt.*;
import javax.swing.*;
public class main extends JFrame
{
public static void main(String args[])
{
Board ex = new Board();
ex.setLayout(null);
System.out.println(ex.getSize());
JFrame frame = new JFrame();
frame.setSize(600,600);
frame.setLocationRelativeTo(null);
frame.add(ex);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setVisible(true);
}
}
