All Implemented Interfaces:: Serializable

Direct Known Subclasses:: ComponentInputMapUIResource

public class ComponentInputMap
extends InputMap
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.

Constructor Detail

ComponentInputMap

public ComponentInputMap(JComponent component)

Creates a ComponentInputMap associated with the specified component.

Parameters:: component - a non-null JComponent
Throws:: IllegalArgumentException - if component is null

Method Detail

setParent

public void setParent(InputMap map)

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.

Overrides:: put in class InputMap

remove

public void remove(KeyStroke key)

Removes the binding for key from this object.

Overrides:: remove in class InputMap

clear

public void clear()

Removes all the mappings from this object.

Overrides:: clear in class InputMap
