• Constructor Detail

  • InputMap

    public InputMap()

    Creates an InputMap with no parent and no mappings.

• Method Detail

  • 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.
