多个JLabel上的鼠标侦听器在一个循环中起作用

Question

我有一个地图作为背景（一个JLabel），我添加了多个Jlabels（作为棋子）。我有一个地图的mouselistener，以便它将我的棋子移动到所需的位置。但它只适用于最后添加的pawn.why是什么？我如何让它循环遍历我的所有jlabels？我正在使用MVC模式。

我需要将mouseListener分配给地图，以便为所有JLabel提供移动区域。

来自Controller的

代码：

this.view.addIconListener(new DragMouseAdapter());

    class DragMouseAdapter extends MouseAdapter {
    private Point initialLoc;
    private Point initialLocOnScreen;

public void mousePressed(MouseEvent e) {
  JComponent comp = (JComponent)e.getSource();
  initialLoc = comp.getLocation();
  initialLocOnScreen = e.getLocationOnScreen();
}

public void mouseReleased(MouseEvent e) {
   /*saySomething("Mouse released; # of clicks: "
                + e.getClickCount(), e);*/
}

public void mouseEntered(MouseEvent e) {
   //saySomething("Mouse entered", e);
}

public void mouseExited(MouseEvent e) {
   //saySomething("Mouse exited", e);
}

public void mouseClicked(MouseEvent e) {


    for(int i = 0; i < 199; i++)
    {
        if((xAxis.get(i) - 15 < e.getX()  && xAxis.get(i) + 15 > e.getX()) && 
            (yAxis.get(i)- 10< e.getY()  && yAxis.get(i) +10 > e.getY() ))
        {
            System.out.println("tada" + (i + 1));
        //System.out.println(x + " " + y);
            view.setCurrentPlayer(model.getCurrentPlayer());
            view.validate();
            //view.addIconListener(this);
            System.out.println(model.getCurrentPlayer());
            view.setPlayerLocation(xAxis.get(i), yAxis.get(i));
            break;
        }
  }
}
