java.lang.Object javax.swing.AbstractAction javax.swing.text.TextAction
An Action implementation useful for key bindings that are shared across a number of different text components. Because the action is shared, it must have a way of getting it's target to act upon. This class provides support to try and find a text component to operate on. The preferred way of getting the component to act upon is through the ActionEvent that is received. If the Object returned by getSource can be narrowed to a text component, it will be used. If the action event is null or can't be narrowed, the last focused text component is tried. This is determined by being used in conjunction with a JTextController which arranges to share that information with a TextAction.
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 TM has been added to the java.beans package. Please see XMLEncoder .
