Use a JSeparator bean to visually separate other components. It is commonly used to draw a horizontal line between groups of related choices in a menu, but can also be used to separate components on a panel.
Use a MenuSeparator bean, rather than a JSeparator bean, if you want to use it in an AWT menu. Although Swing and AWT beans can be mixed, it is inadvisable.
