All known Subclasses:   org.syntax.jedit .DefaultInputHandler,
InputHandler
abstract public class InputHandler extends KeyAdapter (Code)
An input handler converts the user's key strokes into concrete actions. It also takes care of macro recording and action repetition.
This class provides all the necessary support code for an input handler, but doesn't actually do any key binding logic. It is up to the implementations of this class to do so.

Method Detail
addDefaultKeyBindings
abstract public void addDefaultKeyBindings()(Code)
Adds the default key bindings to this input handler. This should not be called in the constructor of this input handler, because applications might load the key bindings from a file, etc.

addKeyBinding
abstract public void addKeyBinding(String keyBinding, ActionListener action)(Code)
Adds a key binding to this input handler.
Parameters:
  keyBinding - The key binding (the format of this isinput-handler specific)
Parameters:
  action - The action

copy
abstract public InputHandler copy()(Code)
Returns a copy of this input handler that shares the same key bindings. Setting key bindings in the copy will also set them in the original.

executeAction
public void executeAction(ActionListener listener, Object source, String actionCommand)(Code)
Executes the specified action, repeating and recording it as necessary.
Parameters:
  listener - The action listener
Parameters:
  source - The event source
Parameters:
  actionCommand - The action command

getAction
public static ActionListener getAction(String name)(Code)
Returns a named text area action.
Parameters:
  name - The action name

getActionName
public static String getActionName(ActionListener listener)(Code)
Returns the name of the specified text area action.
Parameters:
  listener - The action

getActions
public static Enumeration getActions()(Code)
Returns an enumeration of all available actions.

getMacroRecorder
public InputHandler.MacroRecorder getMacroRecorder()(Code)
Returns the macro recorder. If this is non-null, all executed actions should be forwarded to the recorder.

getRepeatCount
public int getRepeatCount()(Code)
Returns the number of times the next action will be repeated.

getTextArea
public static JEditTextArea getTextArea(EventObject evt)(Code)
Returns the text area that fired the specified event.
Parameters:
  evt - The event

grabNextKeyStroke
public void grabNextKeyStroke(ActionListener listener)(Code)
Grabs the next key typed event and invokes the specified action with the key as a the action command.
Parameters:
  action - The action

handleGrabAction
protected void handleGrabAction(KeyEvent evt)(Code)
If a key is being grabbed, this method should be called with the appropriate key event. It executes the grab action with the typed character as the parameter.

isRepeatEnabled
public boolean isRepeatEnabled()(Code)
Returns if repeating is enabled. When repeating is enabled, actions will be executed multiple times. This is usually invoked with a special key stroke in the input handler.

removeAllKeyBindings
abstract public void removeAllKeyBindings()(Code)
Removes all key bindings from this input handler.

removeKeyBinding
abstract public void removeKeyBinding(String keyBinding)(Code)
Removes a key binding from this input handler.
Parameters:
  keyBinding - The key binding

setMacroRecorder
public void setMacroRecorder(InputHandler.MacroRecorder recorder)(Code)
Sets the macro recorder. If this is non-null, all executed actions should be forwarded to the recorder.
Parameters:
  recorder - The macro recorder

setRepeatCount
public void setRepeatCount(int repeatCount)(Code)
Sets the number of times the next action will be repeated.
Parameters:
  repeatCount - The repeat count

setRepeatEnabled
public void setRepeatEnabled(boolean repeat)(Code)
Enables repeating. When repeating is enabled, actions will be executed multiple times. Once repeating is enabled, the input handler should read a number from the keyboard.
