How to add close button to a JTabbedPane Tab?

Question

I\'m working in with a JTabbedPane, I need to add a close button in the tabs to close the current one.

I have been searching and as I understand I must extend from J

You can have a JLabel named "x" and use the mouseListener

 private final JLabel l = new JLabel(); // this is the label for tabbedPane
 private final JLabel b = new JLabel("x");//Close Button
 if (closeable)
        {
            b.setToolTipText("Click to close");

            b.setOpaque(false);
            b.setBackground(Color.gray);

            b.addMouseListener(new MouseAdapter()
            {
                @Override
                public void mouseExited(MouseEvent e)
                {
                    b.setBorder(bordere);
                    b.setOpaque(false);
                }

                @Override
                public void mouseEntered(MouseEvent e)
                {
                    b.setBorder(borderl);
                }

                @Override
                public void mouseReleased(MouseEvent e)
                {
                    b.setOpaque(false);
                    b.repaint();

                    if (b.contains(e.getPoint()))
                    {
                        b.setBorder(borderl);

                        if (confirmTabClosing())
                        {
                            tab.remove(tabIndex());
                            if(tab.getTabCount() == 0)
                                spacialTabComponent.maximizeOrRestore.doClick();
                        }
                    }
                    else
                        b.setBorder(bordere);

                }

                @Override
                public void mousePressed(MouseEvent e)
                {
                    b.setOpaque(true);
                    b.repaint();
                }
            });

            b.setBorder(bordere);
            add(b, getLeftAlignedBothFilledGBC(1, 0, new Insets(0, 0, 0, 0), 0, 0));
        }
