public class ComponentInputMap

extends InputMap

A ComponentInputMap is an InputMap associated with a particular JComponent. The component is automatically notified whenever the ComponentInputMap changes. ComponentInputMaps are used for WHEN_IN_FOCUSED_WINDOW bindings.

Constructor Summary

ComponentInputMap(JComponent component)           Creates a ComponentInputMap associated with the specified component.

 

Method Summary
void	clear()           Removes all the mappings from this object.
JComponent	getComponent()           Returns the component the InputMap was created for.
void	put(KeyStroke keyStroke, Object actionMapKey)           Adds a binding for keyStroke to actionMapKey.
void	remove(KeyStroke key)           Removes the binding for key from this object.
void	setParent(InputMap map)           Sets the parent, which must be a ComponentInputMap associated with the same component as this ComponentInputMap.
