Scrollable JMenu?

Question

Hello everyone,
I've recently been creating a small chat program, and I figured I had enough base essentials that it was time to add some customization. I want a font menu that will give the user to change the message box (JTextArea) to any font that is installed on their system and to set a size between 8 and 14. To do this, I used the following code:
JMenu fontMenu = new JMenu("Font");
        customize.add(fontMenu);
        //TODO make this scrollable
        GraphicsEnvironment e = GraphicsEnvironment.getLocalGraphicsEnvironment();
        Font[] fonts = e.getAllFonts(); // Get the fonts
        for (Font f : fonts)
            final Font font = new Font(f.getName(), f.getStyle(), 10);
            JMenuItem fontItem = new JMenuItem(f.getName());
            fontMenu.add(fontItem);
            fontItem.addActionListener(new ActionListener()
                @Override
                public void actionPerformed (ActionEvent ae)
                    boolean ok = true;
                    do
                        String stringSize = JOptionPane.showInputDialog(null,"Enter a font size between 8 " +
                                  "and 14", "Font Size", JOptionPane.QUESTION_MESSAGE);
                        try
                            int size = Integer.parseInt(stringSize);
                            if (size < 8 || size > 14)
                                ok = false;
                            else
                                ok = true;
                                convArea.setFont(new Font(font.getName(), font.getStyle(), size));
                                systemMessage("Font changed to " + convArea.getFont().getName() +
                                        ", size " + convArea.getFont().getSize());
                        catch (NumberFormatException ex)
                            ok = false;
                    }while (!ok);
        }Just so you know, customize is the name of a JMenu. systemMessage is a method to post a certain message on one user's message box. That's all well and good, but there's so many fonts installed on a system that it spills way off the screen, as shown in this screenshot: http://i36.tinypic.com/21evzpk.png
How could I make that the JMenu fontMenu limited to approximately 10 JMenuItems visible at once, and then make it scrollable using a scrollbar or the mouse wheel or scroll buttons (similar to the bookmarks menu in Firefox or Google Chrome when there are a lot of bookmarks).
Any help would be greatly appreciated. Thanks in advance.

This is great! I'll work on implementing it tomorrow. Thanks.
And I'll consider that in the future. Sorry, kind of new to the forums and haven't had time to look around. I was flustered and found the first semi-applicable location and fired my question.
