An implementation of a menu separator -- 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.
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. A future release of Swing will provide support for long term persistence.
