javax.swing.JSeparator
JSeparator provides a general purpose component for
implementing divider lines - most commonly used as a divider
between menu items that breaks them up into logical groupings.
Instead of using JSeparator directly,
you can use the JMenu or JPopupMenu
addSeparator method to create and add a separator.
JSeparators may also be used elsewhere in a GUI
wherever a visual divider is useful.
For more information and examples see How to Use Menus, a section in The Java Tutorial.
Warning:
Serialized objects of this class will not be compatible with
future Swing releases. The current serialization support is
appropriate for short term storage or RMI between applications running
the same version of Swing. As of 1.4, support for long term storage
of all JavaBeansTM
has been added to the java.beans package.
Please see XMLEncoder.
