@JavaBean(defaultProperty="UI", description="A divider between menu items.") public class JSeparator extends JComponent implements SwingConstants, Accessible
JSeparatorprovides 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 usingJSeparatordirectly, you can use theJMenuorJPopupMenuaddSeparatormethod 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: Swing is not thread safe. For more information see Swing's Threading Policy.
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 JavaBeans™ has been added to the
java.beanspackage. Please seeXMLEncoder.- Since:
- 1.2
