包含卡布局的网格布局 - 可以完成吗？

Question

的目标是显示单元，其中所有单元都彼此独立的表，每个单元有几个可选的显示器（试想一个数谜板，危险板，分机）

这是我在挥杆的第一次尝试。经过大量的阅读，我决定我的方法是首先使用卡片布局（这部分我很满意）独立设计每个单元格，然后将其“包裹”在网格布局中。 这可能是我的地方缺乏基本的Swing理解提高其头：

当设计我创建了一个框架和面板添加到它的每个单元：

import javax.swing.*; 
    import java.awt.*; 
    import java.awt.event.ActionEvent; 
    import java.awt.event.ActionListener; 

    public class Cell extends Component{ 

    JFrame frame = new JFrame(); 

    /* we'll use a card layout with a panel for each look of the cell */ 
    CardLayout cardLayout = new CardLayout(); 
    JPanel containterPanel = new JPanel(); 
    JPanel firstPanel = new JPanel(); 
    JPanel secondPanel = new JPanel(); 
    JPanel thridpanel = new JPanel(); 

    public Cell(){ 

     /* assign the card layout to the container panel */ 
     containterPanel.setLayout(cardLayout); 

     /* assign objects to the different panels - details not important for the sake of the question */ 
     //.... 

     /* add the different panels to the container panel and show the initial one */ 
     containterPanel.add(firstPanel, "firstPanel"); 
     containterPanel.add(secondPanel, "secondPanel"); 
     containterPanel.add(thridpanel, "thridpanel"); 
     cardLayout.show(containterPanel, "firstPanel"); 

     /* add the container to the frame and display it*/ 
     frame.add(containterPanel); 
     frame.setVisible(true); 
    } 
} 

这很好地表现。 但我试图把它包在一个网格布局，其中每个单元的行为就像这是很笨拙：

import java.awt.*; 


public class Board{ 

    private static final int COLUMNS_NUM = 3; 
    private static final int ROWS_NUM = 3; 

    JFrame frame = new JFrame(); 
    JPanel panel = new JPanel(); 
    Cell cells[] = new Cell[COLUMNS_NUM * ROWS_NUM]; 

    public Board(){ 

     panel.setLayout(new GridLayout(ROWS_NUM, COLUMNS_NUM)); 
     for (int i = 0; i <ROWS_NUM * COLUMNS_NUM; i++) 
     { 
      cells[i] = new Cell(); 
      panel.add(cells[i]); 
     } 

     frame.add(panel); 
     frame.setVisible(true); 
    } 

    public static void main(String[] args) { 
     new Board(); 
    } 

} 

我得到的是一堆不相关的帧，从主板框架分离。很明显，我没有正确处理帧（应该只创建一个..？）。 任何帮助引导我到正确的方法将不胜感激。

如果细胞被添加到董事会，让他们一个JPanel，而不是一个JFrame

一个例子：

进口java.awt.CardLayout中; import javax.swing.JLabel; import javax.swing.JPanel;

//make it a sub class of JPanel for easier implementation. 
public class Cell extends JPanel{ 

    public Cell(){ 

     JPanel firstPanel = new JPanel(); 
     //add a lable just so something is displayed 
     firstPanel.add(new JLabel(("Panel 1"))); 
     JPanel secondPanel = new JPanel(); 
     JPanel thridpanel = new JPanel(); 

     CardLayout cardLayout = new CardLayout(); 
     /* assign the card layout */ 
     setLayout(cardLayout); 

     /* add the different panels to the container panel and show the initial one */ 
     add(firstPanel, "firstPanel"); 
     add(secondPanel, "secondPanel"); 
     add(thridpanel, "thridpanel"); 
     cardLayout.show(this, "firstPanel"); 
    } 
} 

和电路板，以保持电池：

import java.awt.Dimension; 
import java.awt.GridLayout; 

import javax.swing.JFrame; 
import javax.swing.JPanel; 
import javax.swing.WindowConstants; 


//make it a sub class of JFrame for easier implementation. 
public class Board extends JFrame{ 

    private static final int COLUMNS_NUM = 3; 
    private static final int ROWS_NUM = 3; 

    Cell cells[] = new Cell[COLUMNS_NUM * ROWS_NUM]; 

    public Board(){ 

     setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE); 
     setPreferredSize(new Dimension(800, 800)); 

     JPanel panel = new JPanel(); 
     add(panel); //or better getContentPane().add(panel); 
     panel.setLayout(new GridLayout(ROWS_NUM, COLUMNS_NUM)); 

     for (int i = 0; i <(ROWS_NUM * COLUMNS_NUM); i++) 
     { 
      cells[i] = new Cell(); 
      panel.add(cells[i]); 
     } 

     pack(); 
     setVisible(true); 
    } 

    public static void main(String[] args) { 
     new Board(); 
    } 
} 

这是怎么样子：
