Field Detail

KEY_TYPED

public static final int KEY_TYPED

The "key typed" event. This event is generated when a character is entered. In the simplest case, it is produced by a single key press. Often, however, characters are produced by series of key presses, and the mapping from key pressed events to key typed events may be many-to-one or many-to-many.

Constant Field Values

KEY_PRESSED

public static final int KEY_PRESSED

The "key pressed" event. This event is generated when a key is pushed down.

Constant Field Values

KEY_RELEASED

public static final int KEY_RELEASED

The "key released" event. This event is generated when a key is let up.

Constant Field Values

keyCode

protected int keyCode

The unique value assigned to each of the keys on the keyboard. There is a common set of key codes that can be fired by most keyboards. The symbolic name for a key code should be used rather than the code value itself.

keyChar

protected char keyChar

keyChar is a valid unicode character that is fired by a key or a key combination on a keyboard.

keyLocation

protected int keyLocation

The key location.
