Interface Keymap


public interface Keymap

A collection of bindings of KeyStrokes to actions. The bindings are basically name-value pairs that potentially resolve in a hierarchy.


Method Summary
 void addActionForKeyStroke(KeyStroke key, Action a)
          Adds a binding to the keymap.
 Action getAction(KeyStroke key)
          Fetches the action appropriate for the given symbolic event sequence.
 Action[] getBoundActions()
          Fetches all of the actions defined in this keymap.
 KeyStroke[] getBoundKeyStrokes()
          Fetches all of the keystrokes in this map that are bound to some action.
 Action getDefaultAction()
          Fetches the default action to fire if a key is typed (i.e.
 KeyStroke[] getKeyStrokesForAction(Action a)
          Fetches the keystrokes that will result in the given action.
 String getName()
          Fetches the name of the set of key-bindings.
 Keymap getResolveParent()
          Fetches the parent keymap used to resolve key-bindings.
 boolean isLocallyDefined(KeyStroke key)
          Determines if the given key sequence is locally defined.
 void removeBindings()
          Removes all bindings from the keymap.
 void removeKeyStrokeBinding(KeyStroke keys)
          Removes a binding from the keymap.
 void setDefaultAction(Action a)
          Set the default action to fire if a key is typed.
 void setResolveParent(Keymap parent)
          Sets the parent keymap, which will be used to resolve key-bindings.
 

Method Detail

getName

String getName()
Fetches the name of the set of key-bindings.

Returns:
the name

getDefaultAction

Action getDefaultAction()
Fetches the default action to fire if a key is typed (i.e. a KEY_TYPED KeyEvent is received) and there is no binding for it. Typically this would be some action that inserts text so that the keymap doesn't require an action for each possible key.

Returns:
the default action

setDefaultAction

void setDefaultAction(Action a)
Set the default action to fire if a key is typed.

Parameters:
a - the action

getAction

Action getAction(KeyStroke key)
Fetches the action appropriate for the given symbolic event sequence. This is used by JTextController to determine how to interpret key sequences. If the binding is not resolved locally, an attempt is made to resolve through the parent keymap, if one is set.

Parameters:
key - the key sequence
Returns:
the action associated with the key sequence if one is defined, otherwise null

getBoundKeyStrokes

KeyStroke[] getBoundKeyStrokes()
Fetches all of the keystrokes in this map that are bound to some action.

Returns:
the list of keystrokes

getBoundActions

Action[] getBoundActions()
Fetches all of the actions defined in this keymap.

Returns:
the list of actions

getKeyStrokesForAction

KeyStroke[] getKeyStrokesForAction(Action a)
Fetches the keystrokes that will result in the given action.

Parameters:
a - the action
Returns:
the list of keystrokes

isLocallyDefined

boolean isLocallyDefined(KeyStroke key)
Determines if the given key sequence is locally defined.

Parameters:
key - the key sequence
Returns:
true if the key sequence is locally defined else false

addActionForKeyStroke

void addActionForKeyStroke(KeyStroke key,
                           Action a)
Adds a binding to the keymap.

Parameters:
key - the key sequence
a - the action

removeKeyStrokeBinding

void removeKeyStrokeBinding(KeyStroke keys)
Removes a binding from the keymap.

Parameters:
keys - the key sequence

removeBindings

void removeBindings()
Removes all bindings from the keymap.


getResolveParent

Keymap getResolveParent()
Fetches the parent keymap used to resolve key-bindings.

Returns:
the keymap

setResolveParent

void setResolveParent(Keymap parent)
Sets the parent keymap, which will be used to resolve key-bindings.

Parameters:
parent - the parent keymap
