javax.swing.JComponent
   javax.swing.JToolTip

JToolTip
public class JToolTip extends JComponent implements Accessible(Code)
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.

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

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 JavaBeansTM has been added to the java.beans package. Please see java.beans.XMLEncoder .
