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.

Since:: 1.3

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`.

Sets the parent, which must be a ComponentInputMap associated with the same component as this ComponentInputMap.

Overrides:: setParent in class InputMap

Parameters:: map - a ComponentInputMap
Throws:: IllegalArgumentException - if map is not a ComponentInputMap or is not associated with the same component

getComponent

public JComponent getComponent()

Returns the component the InputMap was created for.

put

public void put(KeyStroke keyStroke,
 Object actionMapKey)

Adds a binding for keyStroke to actionMapKey. If actionMapKey is null, this removes the current binding for keyStroke.

remove

public void remove(KeyStroke key)

Removes the binding for key from this object.

Overrides:: remove in class InputMap

clear

public void clear()
