我试图下一盘棋，但当我试图通过jlabel图标插入棋子时，它们会覆盖实际的棋盘，因此只有棋子留在屏幕上。我怎样才能使这些标签不掩盖它背后的画呢？我是用一个扩展japplet的类来实现的。
更新：它通过使用applet而不是japplet工作，尽管我仍然不知道为什么。
代码如下：

ChessBoard board;   // done in another class file

public static int CEL_WIDTH = 65; 
public static int MARGIN_X = 50, MARGIN_Y = 50;   

imagePos = "../src/Schack/Bilder/";

JLabel label; 

public void init() {

    setLayout(null);

    this.setSize(600, 600);

    board = new ChessBoard(MARGIN_X, MARGIN_Y, CEL_WIDTH);   

    ImageIcon imageIcon = new ImageIcon(getImage(getDocumentBase(), imagePos + "blackRook.png"));  //scaling  my image 
    Image image = imageIcon.getImage(); 
    Image newimg = image.getScaledInstance(CEL_WIDTH, CEL_WIDTH,  java.awt.Image.SCALE_SMOOTH); 
    imageIcon = new ImageIcon(newimg);  

    label = new JLabel(imageIcon);
    label.setBounds(MARGIN_X, MARGIN_Y, CEL_WIDTH, CEL_WIDTH);

    add(label);           

}

@Override
public void paint(Graphics g) {

    board.paintChessBoard(g);  // another paint method in a different class file 

    super.paint(g);

}
