As of Java 2 platform v1.3 this undocumented class is no longer used. The recommended approach to creating bindings is to use a combination of an ActionMap
, to contain the action, and an InputMap
to contain the mapping from KeyStroke to action description. The InputMap is is usually described in the LookAndFeel tables.
Please refer to the key bindings specification for further details.
This class should be treated as a "protected" inner class. Instantiate it only within subclasses of Foo
.
