Creating a custom panel:

**xterradaniel** · 10-03-2010, 08:01 PM

I need to create a custom panel that resembles a tic tac toe board. I need it to have x's and 0'x and blank spaces put randomly in the grid (3 x 3). Here is what I have so far but I can't seem to finish it. I have only gotten this far due to some help on another forum, but now I am lost!

What I have thus far:

Java Code:

import java.awt.GridLayout;
import java.util.Random;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.SwingConstants;

public class Test2 extends JFrame {
	
	// Use a Constructor...
	public Test2() {
	       // Set up all of the basics.
	       setSize(200, 200);
	       setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
	       setLocationRelativeTo(null);
	       setTitle("Tic Tac Toe");
	       
	       // Add the panel to the JFrame:
	       add(new TicTacToeBoard());
	       
	       // Now, make the JFrame visible
	       setVisible(true);
	}

    public static void main(String[] args) {
    	// Make the main really small and simply call the constructor.
    	new Test2();
       
    }
}

// Pull the class out to here.
class TicTacToeBoard extends JPanel {
    //store the text in an array
    String[] text = {"X", "O", " "};
    Random rand = new Random();
    // use a Random object to randomly select text
    String randomText = text[rand.nextInt(text.length)];

    private JLabel[][] label;

    TicTacToeBoard() {
        super(new GridLayout(3, 3));
        label = new JLabel[3][3];
        for (int i = 0; i < 3; i++) {
            for (int j = 0; j < 3; j++) {
                label[i][j] = new JLabel();
                label[i][j].setHorizontalAlignment(SwingConstants.CENTER);
                add(label[i][j]);
                
                // Give them some text. Just for you to see...
                label[i][j].setText(i + " " + j);
            }
        }
    }

    void setXat(int x, int y) {
        label[x][y].setText("X");
    }

    void setOat(int x, int y) {
        label[x][y].setText("O");
    }

}
