/**
* An event which indicates that a keystroke occurred in a component.
* <p>
* 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 <code>KeyListener</code>
* or <code>KeyAdapter</code> object which registered to receive such
* events using the component's <code>addKeyListener</code> method.
* (<code>KeyAdapter</code> objects implement the
* <code>KeyListener</code> interface.) Each such listener object
* gets this <code>KeyEvent</code> when the event occurs.
* <p>
* <em>"Key typed" events</em> are higher-level and generally do not depend on
* the platform or keyboard layout. They are generated when a Unicode 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 Unicode
* characters (e.g., action keys, modifier keys, etc.).
* <p>
* The getKeyChar method always returns a valid Unicode character or
* CHAR_UNDEFINED. Character input is reported by KEY_TYPED events:
* KEY_PRESSED and KEY_RELEASED events are not necessarily associated
* with character input. Therefore, the result of the getKeyChar method
* is guaranteed to be meaningful only for KEY_TYPED events.
* <p>
* For key pressed and key released events, the getKeyCode method returns
* the event's keyCode. For key typed events, the getKeyCode method
* always returns {@code VK_UNDEFINED}. The {@code getExtendedKeyCode} method
* may also be used with many international keyboard layouts.
*
* <p>
* <em>"Key pressed" and "key released" events</em> 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 {@code getKeyCode} and {@code getExtendedKeyCode}
* methods, which return a virtual key code.
*
* <p>
* <em>Virtual key codes</em> are used to report which keyboard key has
* been pressed, rather than a character generated by the combination
* of one or more keystrokes (such as "A", which comes from shift and "a").
*
* <p>
* 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.
*
* <p>
* Pressing and releasing a key on the keyboard results in the generating
* the following key events (in order):
* <PRE>
* {@code KEY_PRESSED}
* {@code KEY_TYPED} (is only generated if a valid Unicode character could be generated.)
* {@code KEY_RELEASED}
* </PRE>
*
* But in some cases (e.g. auto-repeat or input method is activated) the order
* could be different (and platform dependent).
*
* <p>
* Notes:
* <ul>
* <li>Key combinations which do not result in Unicode characters, such as action
* keys like F1 and the HELP key, do not generate KEY_TYPED events.
* <li>Not all keyboards or systems are capable of generating all
* virtual key codes. No attempt is made in Java to generate these keys
* artificially.
* <li>Virtual key codes do not identify a physical key: they depend on the
* platform and keyboard layout. For example, the key that generates VK_Q
* when using a U.S. keyboard layout will generate VK_A when using a French
* keyboard layout.
* <li>The key that generates {@code VK_Q} when using a U.S. keyboard layout also
* generates a unique code for Russian or Hebrew layout. There is no a
* {@code VK_} constant for these and many other codes in various layouts. These codes
* may be obtained by using {@code getExtendedKeyCode} and are used whenever
* a {@code VK_} constant is used.
* <li>Not all characters have a keycode associated with them. For example,
* there is no keycode for the question mark because there is no keyboard
* for which it appears on the primary layer.
* <li>In order to support the platform-independent handling of action keys,
* the Java platform uses a few additional virtual key constants for functions
* that would otherwise have to be recognized by interpreting virtual key codes
* and modifiers. For example, for Japanese Windows keyboards, VK_ALL_CANDIDATES
* is returned instead of VK_CONVERT with the ALT modifier.
* <li>As specified in <a href="../doc-files/FocusSpec.html">Focus Specification</a>
* key events are dispatched to the focus owner by default.
* </ul>
*
* <p>
* 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 accommodate a wider range of keyboards in the future.
* <p>
* An unspecified behavior will be caused if the {@code id} parameter
* of any particular {@code KeyEvent} instance is not
* in the range from {@code KEY_FIRST} to {@code KEY_LAST}.
