How do I do that?
Also, I played around with the setAlignmentX method to line components up on the panel, but I couldn't get them to line up correctly. What components should I be aligning? The panel? The labels? Currently if there is a menu option that is too long, that menu will be aligned wrong. How can I align the labels so that all my menus look the same? Should I create a separate class to handle the menus?
