public class JToolTip

extends JComponent

implements Accessible

Used to display a "Tip" for a Component. Typically components provide api to automate the process of using ToolTips. For example, any Swing component can use the JComponent setToolTipText method to specify the text for a standard tooltip. A component that wants to create a custom ToolTip display can override JComponent's createToolTip method and use a subclass of this class.

For the keyboard keys used by this component in the standard Look and Feel (L&F) renditions, see the JToolTip key assignments.

See How to Use Tool Tips in The Java Tutorial for further documentation.

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.
