Thread: Chess Program

Guys,

I am developing a chess manager program(not an interactive game)!

I have the following classes in my model package

ChessPieces
ChessBoard contains Squares in an ArrayList and chessPieces in an ArrayList
Square

Also in my view package i have a chessboardview

Its a JPanel ill post the code below.
Is there a way the get all the 64 squares in my JPanel with ImageIcon?
CHESSBOARD

package model;
 
import java.util.Set;
import java.util.ArrayList;
 
import javax.swing.ImageIcon;
 
public class ChessBoard {
 
    private Set<ChessPiece> chessPieces;
    private ArrayList<Square> squares;
    private static final String[] LOCATIONS = {
    "A1","B1","C1","D1","E1","F1","G1","H1",
    "A2","B2","C2","D2","E2","F2","G2","H2",
    "A3","B3","C3","D3","E3","F3","G3","H3",
    "A4","B4","C4","D4","E4","F4","G4","H4",
    "A5","B5","C5","D5","E5","F5","G5","H5",
    "A6","B6","C6","D6","E6","F6","G6","H6",
    "A7","B7","C7","D7","E7","F7","G7","H7",
    "A8","B8","C8","D8","E8","F8","G8","H8",
    };
 
    public ChessBoard(){ 
        squares = new ArrayList<Square>();
        addLocations();
        setSquareColors();
    }
 
    private void addLocations(){
        for(int i = 0; i < LOCATIONS.length; i++){
        	squares.add(new Square(LOCATIONS[i]));    
        }       
    }
 
    private void setSquareColors(){
    	for(int i = 0; i < LOCATIONS.length; i++){
    	    squares.get(i).setColor("BROWN");
    	}
    	for(int i = 1; i < LOCATIONS.length-1; i++){
    	    squares.get(i).setColor("WHITE");
    	}
    }
 
    public Square getSquare(int i){
        return squares.get(i);
    }
 
    public String getSquareColor(int i){
        return squares.get(i).getColor();
    }
 
    public ArrayList<Square> getAllSquares(){
    	return squares;
    }
 
    public void setSquareImage(int i, ImageIcon image){
    	getSquare(i).setImage(image);
    }
}

SQUARE

hello
try to make the class square of type jpanel and override the paintComponent method to place the images in it. then you should be able to place as many squares as you want in the chess board.
thanks

can you code an example for me?

--- Update ---

8x8 grid of JPanels that could hold images.

i all ready have that right?

setLayout( new GridLayout(8, 8) );
setPreferredSize( boardSize );
setBounds(10, 10, boardSize.width, boardSize.height);
setBorder(BorderFactory.createLineBorder(Color.BLACK));

this layout sets the jpanel layout from the class chessboardview. It is actually a super to extends jpanel
i really cant get the squares in a 64 panel which contains the squares with location an image to represent a chess board

Okay i made my square class JLabel what next? I have 64 different square objects, each with different locations.

import javax.swing.JLabel;
 
public class Square extends JLabel{

but what next to do in the chessboardview class? how to add all 64 squares in the right position

i need something like

for (int i = 0; i < 64; i++) {
 
 
	            int row = (i / 8) % 2;
	            if (row == 0)

but what next? to add 64 squares alternately coloured brown and white

the location value and the color and image are set correctly the arraylist contains 64 squares with string location, string color, ImageIcon image. Now in the chessboardview which extends JPanel(chess board) i need to implement those 64 squares in the JPanel which has a gridlayout(8,8) but i i have no idea how? do i have to make 64 JLabels and how can i place them in the right order etc.

you can change the logic so that they are correctly positioned.

how do i change a grid logic so the labels are set correctly?

i dont know how to change a gridlayout so it contains 64 jlabels in the right order

what do you mean by what order? thanks for you help!

public class ChessBoardView extends JPanel

    //intialize variables

how do i place 64 squares in the right order?

I dont know which JLabels

public class ChessBoard {
 
    private Set<ChessPiece> chessPieces;
    private ArrayList<Square> squares;
    private static final String[] LOCATIONS = {
    "A1","B1","C1","D1","E1","F1","G1","H1",
    "A2","B2","C2","D2","E2","F2","G2","H2",
    "A3","B3","C3","D3","E3","F3","G3","H3",
    "A4","B4","C4","D4","E4","F4","G4","H4",
    "A5","B5","C5","D5","E5","F5","G5","H5",
    "A6","B6","C6","D6","E6","F6","G6","H6",
    "A7","B7","C7","D7","E7","F7","G7","H7",
    "A8","B8","C8","D8","E8","F8","G8","H8",
    };
 
    public ChessBoard(){ 
        squares = new ArrayList<Square>();
        addLocations();
        setSquareColors();
    }
 
    private void addLocations(){
        for(int i = 0; i < LOCATIONS.length; i++){
        	squares.add(new Square(LOCATIONS[i]));    
        }       
    }
 
    private void setSquareColors(){
    	for(int i = 0; i < LOCATIONS.length; i++){
    	    squares.get(i).setColor("BROWN");
    	}
    	for(int i = 1; i < LOCATIONS.length-1; i++){
    	    squares.get(i).setColor("WHITE");
    	}
    }

				}
			}
	}
 
	private void addSquaresToContentPane(){
		super.add(new JLabel (chessboard.getSquare(0).getImage()));
 
 
		}
 
	}

how did you get that? which code?

 private void createGUI() {
		Dimension boardSize = new Dimension(200, 200);
 
	    setLayout( new GridLayout(8, 8) );
	    setPreferredSize( boardSize );
	    setBounds(10, 10, boardSize.width, boardSize.height);
	    setBorder(BorderFactory.createLineBorder(Color.BLACK));
 
	    addImageToSquare();
	    addSquaresToContentPane();
	}

can you post the code?

which method are you talking about?

--- Update ---

can you please post the code you made to get to the point of the grid with all the labels and icons in it
