Constructors

InputMap

public InputMap()

Creates an InputMap with no parent and no mappings.

Methods

setParent

public void setParent(InputMap map)

Sets this InputMap's parent.

Parameters:

map - the InputMap that is the parent of this one

getParent

public InputMap getParent()

Gets this InputMap's parent.

Returns:

map the InputMap that is the parent of this one, or null if this InputMap has no parent

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.

get

public Object get(KeyStroke keyStroke)

Returns the binding for keyStroke, messaging the parent InputMap if the binding is not locally defined.

remove

public void remove(KeyStroke key)

Removes the binding for key from this InputMap.

clear

public void clear()

Removes all the mappings from this InputMap.

keys

public KeyStroke[] keys()

Returns the KeyStrokes that are bound in this InputMap.

size

public int size()

Returns the number of KeyStroke bindings.

allKeys

public KeyStroke[] allKeys()

Returns an array of the KeyStrokes defined in this InputMap and its parent. This differs from keys() in that this method includes the keys defined in the parent.
