SUMMARY: INNER | FIELD | CONSTR | METHOD | DETAIL: FIELD | CONSTR | METHOD |
java.lang.Object | +--java.util.EventObject | +--java.awt.AWTEvent | +--java.awt.event.ComponentEvent | +--java.awt.event.InputEvent | +--java.awt.event.KeyEvent
An event which indicates that a keystroke occurred in a component.
This low-level event is generated by a component object (such as a text
field) when a key is pressed, released, or typed.
The event is passed to every KeyListener
or KeyAdapter
object which registered to receive such
events using the component's addKeyListener
method.
(KeyAdapter
objects implement the
KeyListener
interface.) Each such listener object
gets this KeyEvent
when the event occurs.
"Key typed" events are higher-level and generally do not depend on the platform or keyboard layout. They are generated when a character is entered, and are the preferred way to find out about character input. In the simplest case, a key typed event is produced by a single key press (e.g., 'a'). Often, however, characters are produced by series of key presses (e.g., 'shift' + 'a'), and the mapping from key pressed events to key typed events may be many-to-one or many-to-many. Key releases are not usually necessary to generate a key typed event, but there are some cases where the key typed event is not generated until a key is released (e.g., entering ASCII sequences via the Alt-Numpad method in Windows). No key typed events are generated for keys that don't generate characters (e.g., action keys, modifier keys, etc.). The getKeyChar method always returns a valid Unicode character or CHAR_UNDEFINED. For key pressed and key released events, the getKeyCode method returns the event's keyCode. For key typed events, the getKeyCode method always returns VK_UNDEFINED.
"Key pressed" and "key released" events are lower-level and depend on the platform and keyboard layout. They are generated whenever a key is pressed or released, and are the only way to find out about keys that don't generate character input (e.g., action keys, modifier keys, etc.). The key being pressed or released is indicated by the getKeyCode method, which returns a virtual key code.
Virtual key codes are used to report which keyboard key has been pressed, rather than a character generated by the combination of one or more keystrokes (like "A", which comes from shift and "a").
For example, pressing the Shift key will cause a KEY_PRESSED event with a VK_SHIFT keyCode, while pressing the 'a' key will result in a VK_A keyCode. After the 'a' key is released, a KEY_RELEASED event will be fired with VK_A. Separately, a KEY_TYPED event with a keyChar value of 'A' is generated.
Notes:
WARNING: Aside from those keys that are defined by the Java language (VK_ENTER, VK_BACK_SPACE, and VK_TAB), do not rely on the values of the VK_ constants. Sun reserves the right to change these values as needed to accomodate a wider range of keyboards in the future.
