Question

我有一个JPanel 7width 9高度板。我也可以将我的棋子放在棋盘上。我现在的问题是如何调用这些部分：伪代码： if（whero1在第0行第5列然后......

代码如下：

public class Board extends JPanel{
private static final String imageFolderPath = "src/resources/images/";
Dimension dimension = new Dimension(500, 500);
JPanel board;
JLabel piece;
MovePiece mp = new MovePiece(this);

public Board(){
  //set size of panel;
  this.setPreferredSize(dimension);
  this.addMouseListener(mp);
  this.addMouseMotionListener(mp);

  //create the Board
  board = new JPanel();
  board.setLayout(new GridLayout(9,7));
  board.setPreferredSize(dimension);
  board.setBounds(0, 0, dimension.width, dimension.height);
  this.add(board);

  for (int i = 0; i < 63; i++) {
    JPanel square = new JPanel(new BorderLayout());
    square.setBorder(BorderFactory.createEtchedBorder(EtchedBorder.RAISED));
    board.add(square);
    square.setBackground(new Color(185, 156, 107));
  }
JLabel whero1 = new JLabel( new ImageIcon(imageFolderPath+"/pieces/bhero.png") );
  JPanel panel = (JPanel)board.getComponent(60);
  panel.add(whero1);

//I'm trying this, but i.m going nowhere
  int x =whero1.getParent().getX();
  int y = whero1.getParent().getY();
  System.out.println(x);
  System.out.println(y);
  /*if(x==0&&y==0){
      whero1.setIcon(new ImageIcon(imageFolderPath+"/pieces/bdg.png"));
  }*/
 }

}

最简单的解决方案是维护董事会的某种虚拟模型。通过这种方式，您可以简单地更新游戏状态并请求UI更新自身以反映模型的状态。

更简单，然后尝试询问n深度包含并转换为/从坐标系

nb：这......

int x =whero1.getParent().getX(); 
int y = whero1.getParent().getY();

是否会返回whereo1父级的像素x / y位置相对于它的父级容器，并不相信这会对它有所帮助

调用jpanel添加到jframe中
