Написание пользовательской панели JPanel, которая будет следовать спецификациям LayoutManager.

Я пытаюсь закодировать пользовательскую JPanel, которая следует за layoutmanager содержащей JPanel (я использую gridbag). Моя пользовательская панель JPanel становится слишком длинной для вставки сюда, но контрольный список всех методов, которые нужно перезаписать, чтобы это работало.

Вот выдержка из моего пользовательского JPanel:

        public class GridPanel extends JPanel implements MouseMotionListener, MouseListener{
            private Rectangle offdutyRect, sbRect, driveRect, onRect;
            private int delta = 60;
            private int[][] gridArray;
            int draggedStartX = -1;
            int draggedStartY = -1;
            private int dutyStatusSpacing = 60;
            private int totalSpacing = 100;

            public GridPanel(){
            this.setSize(new Dimension(800, 100));
            this.addMouseMotionListener((MouseMotionListener) this);
            this.addMouseListener(this);
            int gridArrayColumns = 24*60/delta;
            gridArray = new int[4][gridArrayColumns];

            int r = 0;
            int rHeight = this.getHeight()/4;
            offdutyRect = new Rectangle(this.getX() + dutyStatusSpacing, this.getY() + r*rHeight, this.getWidth() - totalSpacing, rHeight);
            r++;
            sbRect = new Rectangle(this.getX() + dutyStatusSpacing, this.getY() + r*rHeight, this.getWidth() - totalSpacing, rHeight);
            r++;
            driveRect = new Rectangle(this.getX() + dutyStatusSpacing, this.getY() + r*rHeight, this.getWidth() - totalSpacing, rHeight);
            r++;
            onRect = new Rectangle(this.getX() + dutyStatusSpacing, this.getY() + r*rHeight, this.getWidth() - totalSpacing, rHeight);

            Rectangle rect = null;
            for(r = 0; r < gridArray.length; r++){
                if(r == 0){
                rect = offdutyRect;
                }else if(r == 1){
                rect = sbRect;
                }else if(r == 2){
                rect = driveRect;
                }else if(r == 3){
                rect = onRect;
                }

                //I haven't actually derived any of these things, just my best guesses.
                int len = gridArray[r].length;
                int width = (int) (rect.getWidth()/len);
                rect.setSize((int)(width*len), (int) rect.getHeight());
            }
        }

    public void paintComponent(Graphics g){
        g.clearRect(this.getX(), this.getY(), this.getWidth(), this.getHeight());
        //the center black bar for duty status "placeholders"
        g.setColor(Color.black);
        g.drawRect(getX(), getY(), getWidth() - 1, getHeight() - 1);
        g.drawRect((int)offdutyRect.getX(), (int)offdutyRect.getY() + (int)offdutyRect.getHeight()/2, (int)offdutyRect.getWidth(), 1);
        g.drawRect((int)sbRect.getX(), (int)sbRect.getY() + (int)sbRect.getHeight()/2, (int)sbRect.getWidth(), 1);
        g.drawRect((int)driveRect.getX(), (int)driveRect.getY() + (int)driveRect.getHeight()/2, (int)driveRect.getWidth(), 1);
        g.drawRect((int)onRect.getX(), (int)onRect.getY() + (int)onRect.getHeight()/2, (int)onRect.getWidth(), 1);
        g.setColor(Color.pink);
        g.drawRect((int)offdutyRect.getX(), (int)offdutyRect.getY(), (int)offdutyRect.getWidth(), (int)offdutyRect.getHeight());
        g.drawRect((int)sbRect.getX(), (int)sbRect.getY(), (int)sbRect.getWidth(), (int)sbRect.getHeight());
        g.drawRect((int)driveRect.getX(), (int)driveRect.getY(), (int)driveRect.getWidth(), (int)driveRect.getHeight());
        g.drawRect((int)onRect.getX(), (int)onRect.getY(), (int)onRect.getWidth(), (int)onRect.getHeight());

        //draw the array
        g.setColor(Color.green);
        Rectangle rect = null;
        for(int r = 0; r < gridArray.length; r++){
            if(r == 0){
            rect = offdutyRect;
            }else if(r == 1){
            rect = sbRect;
            }else if(r == 2){
            rect = driveRect;
            }else if(r == 3){
            rect = onRect;
            }

            //I haven't actually derived any of these things, just my best guesses.
            int len = gridArray[r].length;
            int width = (int) (rect.getWidth()/len);

            int height = (int) rect.getHeight() - 2;
            for(int c = 0; c < gridArray[r].length; c++){
            if(gridArray[r][c] == 1){
                    int x = (int) (rect.getX() + width*c);
                    int y = (int) rect.getY() + 2;
                    g.fillRect(x, y, width, height);
            }
            }
        }
        }
    //implement setSize
    public void setSize(Dimension d){

    if(gridArray == null){

        int gridArrayColumns = 24*60/delta;
        gridArray = new int[4][gridArrayColumns];
    }
    int r = 0;
    int rHeight = this.getHeight()/4;
    offdutyRect = new Rectangle(this.getX() + dutyStatusSpacing, this.getY() + r*rHeight, (int)d.getWidth() - totalSpacing, rHeight);
    r++;
    sbRect = new Rectangle(this.getX() + dutyStatusSpacing, this.getY() + r*rHeight, (int)d.getWidth() - totalSpacing, rHeight);
    r++;
    driveRect = new Rectangle(this.getX() + dutyStatusSpacing, this.getY() + r*rHeight, (int)d.getWidth() - totalSpacing, rHeight);
    r++;
    onRect = new Rectangle(this.getX() + dutyStatusSpacing, this.getY() + r*rHeight, (int)d.getWidth() - totalSpacing, rHeight);

    Rectangle rect = null;
    for(r = 0; r < gridArray.length; r++){
        if(r == 0){
        rect = offdutyRect;
        }else if(r == 1){
        rect = sbRect;
        }else if(r == 2){
        rect = driveRect;
        }else if(r == 3){
        rect = onRect;
        }

        //I haven't actually derived any of these things, just my best guesses.
        int len = gridArray[r].length;
        int width = (int) (rect.getWidth()/len);
        rect.setSize((int)(width*len), (int) rect.getHeight());
    }
    }

}

А вот относительно короткий пользовательский контейнер, в который будут добавлены несколько экземпляров моего пользовательского класса:

public class GridContainer extends JPanel implements ActionListener{
    List<GridPanel> panels = new ArrayList<GridPanel>();

    public GridContainer(){
    GridBagLayout gb = new GridBagLayout();
    this.setLayout(gb);
    GridBagConstraints c = new GridBagConstraints();

    c.gridx = 0;
    c.gridy = 0;
    c.weightx = .5;
    c.weighty = .5;
    c.fill = GridBagConstraints.HORIZONTAL;
    BufferedImage img = null;
    try {
        img = ImageIO.read(this.getClass().getResource("/res/add.png"));
    } catch (IOException e) { }
    JButton addButton = new JButton();
    addButton.setIcon(new ImageIcon(img));
    addButton.addActionListener(this);
    this.add(addButton, c);
    }

    public void actionPerformed(ActionEvent e) {
    System.out.println("action performed"  +  panels.size());
    this.setLayout(new GridBagLayout());
    removeAll();
    repaint();
    panels.add(new GridPanel());
    int r = 0;
    GridBagConstraints c = new GridBagConstraints();
    for(int i = 0; i < panels.size(); i++){
            JLabel label = new JLabel("day " + i);
            c = new GridBagConstraints();
            c.gridx = 0;
            c.gridy = r;
            c.weightx = 1;
            c.weighty = 1;
            this.add(label, c);
            r++;

            c = new GridBagConstraints();
            c.gridx = 0;
            c.gridy = r;
            c.weightx = 1;
            c.weighty = 1;
            c.fill = GridBagConstraints.HORIZONTAL;
            this.add(panels.get(i), c);
            r++;
    }

    c = new GridBagConstraints();
    c.gridx = 0;
    c.gridy = r;
    c.weightx = 1;
    c.weighty = 1;
    c.fill = GridBagConstraints.HORIZONTAL;
    BufferedImage img = null;
    try {
        img = ImageIO.read(this.getClass().getResource("/res/add.png"));
    } catch (IOException ex) { }
    JButton addButton = new JButton();
    addButton.setIcon(new ImageIcon(img));
    addButton.addActionListener(this);
    this.add(addButton, c);
    repaint();

    }
}

Не чувствуйте себя обязанным отлаживать эту стену кода, просто некоторый контекст того, где я нахожусь.
