Constructor Detail

DefaultInputHandler

public DefaultInputHandler()

Creates a new input handler with no key bindings defined.

---

DefaultInputHandler

public DefaultInputHandler(DefaultInputHandler copy)

Creates a new input handler with the same set of key bindings as the one specified. Note that both input handlers share a pointer to exactly the same key binding table; so adding a key binding in one will also add it to the other.

Method Detail

addDefaultKeyBindings

public void addDefaultKeyBindings()

Sets up the default key bindings.

Specified by:

addDefaultKeyBindings in class InputHandler

---

addKeyBinding

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

Adds a key binding to this input handler. The key binding is a list of white space separated key strokes of the form [modifiers+]key where modifier is C for Control, A for Alt, or S for Shift, and key is either a character (a-z) or a field name in the KeyEvent class prefixed with VK_ (e.g., BACK_SPACE)

Specified by:

addKeyBinding in class InputHandler

---

removeKeyBinding

public void removeKeyBinding(java.lang.String keyBinding)

Removes a key binding from this input handler. This is not yet implemented.

Specified by:

removeKeyBinding in class InputHandler

---

removeAllKeyBindings

public void removeAllKeyBindings()

Removes all key bindings from this input handler.

Specified by:

removeAllKeyBindings in class InputHandler

---

keyPressed

public void keyPressed(java.awt.event.KeyEvent evt)

Handle a key pressed event. This will look up the binding for the key stroke and execute it.

---

keyTyped

public void keyTyped(java.awt.event.KeyEvent evt)

Handle a key typed event. This inserts the key into the text area.

---

parseKeyStroke

public static javax.swing.KeyStroke parseKeyStroke(java.lang.String keyStroke)

Converts a string to a keystroke. The string should be of the form modifiers+shortcut where modifiers is any combination of A for Alt, C for Control, S for Shift or M for Meta, and shortcut is either a single character, or a keycode name from the KeyEvent class, without the VK_ prefix.
