創建一個強大的、可調整大小的Swing Chess GUI
Swing 是一個用於創建圖形用戶界面(GUI) 的Java庫,提供了一個強大的框架用於構建強大且可自訂的應用程式。在本文中,我們將重點放在一個可調整大小的基於Swing 的國際象棋GUI,滿足以下要求:
GUI 版面:
技術方法:
實作細節:
import java.awt.*; import java.awt.event.*; import java.awt.image.BufferedImage; import javax.swing.*; import javax.swing.border.*; import java.net.URL; import javax.imageio.ImageIO; public class ChessGUI { private final JPanel gui = new JPanel(new BorderLayout(3, 3)); private JButton[][] chessBoardSquares = new JButton[8][8]; private Image[][] chessPieceImages = new Image[2][6]; private JPanel chessBoard; private final JLabel message = new JLabel("Chess Champ is ready to play!"); private static final String COLS = "ABCDEFGH"; // Chess piece types public static final int QUEEN = 0, KING = 1, ROOK = 2, KNIGHT = 3, BISHOP = 4, PAWN = 5; public static final int[] STARTING_ROW = { ROOK, KNIGHT, BISHOP, KING, QUEEN, BISHOP, KNIGHT, ROOK }; // Player colors public static final int BLACK = 0, WHITE = 1; public ChessGUI() { initializeGui(); } public final void initializeGui() { createImages(); // Main GUI layout gui.setBorder(new EmptyBorder(5, 5, 5, 5)); JToolBar tools = new JToolBar(); tools.setFloatable(false); gui.add(tools, BorderLayout.PAGE_START); // Toolbar buttons Action newGameAction = new AbstractAction("New") { @Override public void actionPerformed(ActionEvent e) { setupNewGame(); } }; tools.add(newGameAction); tools.add(new JButton("Save")); // Implement later tools.add(new JButton("Restore")); // Implement later tools.addSeparator(); tools.add(new JButton("Resign")); // Implement later tools.addSeparator(); tools.add(message); gui.add(new JLabel("?"), BorderLayout.LINE_START); // Chess board layout chessBoard = new JPanel(new GridLayout(0, 9)) { @Override public final Dimension getPreferredSize() { Dimension d = super.getPreferredSize(); Dimension prefSize = null; Component c = getParent(); // Adjust size to fit within parent component if (c == null) { prefSize = new Dimension((int) d.getWidth(), (int) d.getHeight()); } else if (c != null && c.getWidth() > d.getWidth() && c.getHeight() > d.getHeight()) { prefSize = c.getSize(); } else { prefSize = d; } int w = (int) prefSize.getWidth(); int h = (int) prefSize.getHeight(); // Square shape int s = (w > h ? h : w); return new Dimension(s, s); } }; chessBoard.setBorder(new CompoundBorder(new EmptyBorder(8, 8, 8, 8), new LineBorder(Color.BLACK))); chessBoard.setBackground(new Color(204, 119, 34)); // Ochre color JPanel boardConstrain = new JPanel(new GridBagLayout()); boardConstrain.setBackground(new Color(204, 119, 34)); // Ochre color boardConstrain.add(chessBoard); gui.add(boardConstrain); // Chess board squares Insets buttonMargin = new Insets(0, 0, 0, 0); for (int ii = 0; ii < chessBoardSquares.length; ii++) { for (int jj = 0; jj < chessBoardSquares[ii].length; jj++) { JButton b = new JButton(); b.setMargin(buttonMargin); ImageIcon icon = new ImageIcon(new BufferedImage(64, 64, BufferedImage.TYPE_INT_ARGB)); b.setIcon(icon); if ((jj % 2 == 1 && ii % 2 == 1) || (jj % 2 == 0 && ii % 2 == 0)) { b.setBackground(Color.WHITE); } else { b.setBackground(Color.BLACK); } chessBoardSquares[jj][ii] = b; } } // Initial chess board setup chessBoard.add(new JLabel(""));
