Constructor Detail

JEditInputHandler

public JEditInputHandler()

Method Detail

getAction

public static java.awt.event.ActionListener getAction(java.lang.String name)

Returns a named text area action.

---

getActionName

public static java.lang.String getActionName(java.awt.event.ActionListener listener)

Returns an action's name.

---

getActions

public static java.util.Enumeration getActions()

Returns an enumeration of all available actions.

---

addDefaultKeyBindings

public abstract void addDefaultKeyBindings()

Adds the default key bindings to this input handler.

---

addKeyBinding

public abstract void addKeyBinding(java.lang.String keyBinding,
                                   java.awt.event.ActionListener action)

Adds a key binding to this input handler.

---

removeKeyBinding

public abstract void removeKeyBinding(java.lang.String keyBinding)

Removes a key binding from this input handler.

---

removeAllKeyBindings

public abstract void removeAllKeyBindings()

Removes all key bindings from this input handler.

---

grabNextKeyStroke

public void grabNextKeyStroke(java.awt.event.ActionListener listener)

Grabs the next key typed event and invokes the specified action with the key as a the action command.

---

isRepeatEnabled

public boolean isRepeatEnabled()

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.

---

setRepeatEnabled

public void setRepeatEnabled(boolean repeat)

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.

---

getRepeatCount

public int getRepeatCount()

Returns the number of times the next action will be repeated.

---

setRepeatCount

public void setRepeatCount(int repeatCount)

Sets the number of times the next action will be repeated.

---

getMacroRecorder

public JEditInputHandler.MacroRecorder getMacroRecorder()

Returns the macro recorder. If this is non-null, all executed actions should be forwarded to the recorder.

---

setMacroRecorder

public void setMacroRecorder(JEditInputHandler.MacroRecorder recorder)

Sets the macro recorder. If this is non-null, all executed actions should be forwarded to the recorder.

---

copy

public abstract JEditInputHandler copy()

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(java.awt.event.ActionListener listener,
                          java.lang.Object source,
                          java.lang.String actionCommand)

Executes the specified action.

---

getTextArea

public static JEditTextArea getTextArea(java.util.EventObject evt)

Returns the text area that fired the specified event.

---

handleGrabAction

protected void handleGrabAction(java.awt.event.KeyEvent evt)

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.
