我在尝试使用JLayeredPane进行自己的国际象棋游戏时遇到问题。调整JLayeredPane图层
我能走到今天：
（希望你可以看到块G6对标签呈现出绿色的边框将其选中块）
但是，当我加我2个SidePanel小号我的ChessBoard面板，然后有另一层顶部与标签应该涵盖每个板块，但它没有：
正如您所看到的绿色边框周围块G2已关闭。
当我将SidePanel s添加到ChessBoard并将其添加到底层并将其大小设置为600x600时，我已将其缩小到显而易见的范围，然后添加标签的顶层以适合ChessBoard，并且围绕选定的JLabel（以及更低的ChessBoard方块[黑色或白色]）绘制绿色边框，由于SidePanel s已将棋盘的实际尺寸减小到600x600，所以它现在将会是600-sp1.getWidth() x 600-sp2.getHeight()。我尝试设置顶层的边界和首选大小来弥补它，但似乎没有用。任何帮助表示赞赏谢谢：
ChessBoardTest.java：

SidePanel.java：
class SidePanel extends JPanel {
final static String HORIZONTAL = "horizontal";
final static String VERTICAL = "vertical";
public SidePanel(String[] strings, String direction) {
if (direction.equals(VERTICAL)) {
setLayout(new GridLayout(8, 0));
} else {
setLayout(new GridLayout(0, 8));
}
setDoubleBuffered(true);
for (String string : strings) {
this.add(new JLabel(string, JLabel.CENTER));
}
}
}
ChessBoard.java：
class ChessBoard extends JPanel {
public ChessBoard() {
super(new BorderLayout(), true);
this.add(populateBoard(Color.white, Color.black), BorderLayout.CENTER);
}
private JPanel populateBoard(Color c1, Color c2) {

for (int i = 0; i < 8; i++) {
for (int j = 0; j < 8; j++) {

square.setBackground((i + j) % 2 == 0 ? c1 : c2);
panel.add(square);
}
}
return panel;
}
}
ChessPieceLayer.java：
class ChessPieceLayer extends JComponent {
private HashMap<PiecePanel, String> panelsMap = new HashMap<>(64);
final ChessPieceMouseListener listener;
ChessPieceLayer() {
super();
listener = new ChessPieceMouseListener();
setLayout(new GridLayout(8, 8));

int[] rows = new int[]{1, 2, 3, 4, 5, 6, 7, 8};
String row, col;
int rowCount = 7, colCount = 0, trigger = 8;
for (int i = 0; i < 64; i++) {
if (trigger == 0) {
colCount = 0;
trigger = 8;
rowCount--;
}
col = cols[colCount++];
row = rows[rowCount] + "";
trigger--;
String location = col + row;
PiecePanel square = createAndAddPiecesWithMouseListener(location);
panelsMap.put(square, location);
}
}
private PiecePanel createAndAddPiecesWithMouseListener(String location) {
PiecePanel square = new PiecePanel(location, JLabel.CENTER);
square.addMouseListener(listener);
square.setText(location);
this.add(square);
return square;
}
}
PiecePanel.java：
class PiecePanel extends JLabel {
private String location;
public PiecePanel(String text, int horizontalAlignment) {
super("", horizontalAlignment);
this.location = text;
}
PiecePanel(String location) {
this.location = location;
}
public String getPieceLocation() {
return location;
}
public void setPieceLocation(String location) {
this.location = location;
}
@Override
protected void paintComponent(Graphics g) {
super.paintComponent(g);
}
}
ChessPieceMouseListener.java：
class ChessPieceMouseListener implements MouseListener {
int counter = 0;
PiecePanel this_pp, prev_pp;
@Override
public void mouseClicked(MouseEvent e) {
}
@Override
public void mousePressed(MouseEvent e) {
}
@Override
public void mouseReleased(MouseEvent e) {
PiecePanel pp = (PiecePanel) e.getComponent();
if (counter == 0) {
this_pp = pp;
this_pp.setBorder(new BevelBorder(0, Color.green, Color.green));
JOptionPane.showMessageDialog(null, "From " + pp.getPieceLocation());
counter = 1;
} else {
prev_pp = this_pp;
this_pp = pp;
prev_pp.setBorder(null);
JOptionPane.showMessageDialog(null, "To " + pp.getPieceLocation());
counter = 0;
}
}
@Override
public void mouseEntered(MouseEvent e) {
}
@Override
public void mouseExited(MouseEvent e) {
}
}
在第一我使用：
chessPieceLayer.setPreferredSize(boardSize);
chessPieceLayer.setBounds(0, 0, boardSize.width, boardSize.height);
然后我尝试：
chessPieceLayer.setPreferredSize(new Dimension(600-sp1.getWidth(),600-sp2.getHeight()));
chessPieceLayer.setBounds(0+sp1.getWidth(), 0+sp2.getHeight(), 600-sp1.getWidth(), 600-sp2.getHeight());
但结果犯规不同
你可以张贴棋盘和ChessPiecePlayer的代码？ –
@GuillaumePolet在那里。正在使用内部类，所以它们没有在自己的文件中声明，当然这只是测试。但我现在将其分开以便于查看 –
