/**
|
||
* This event is generated when a key is pressed or released. There are two
|
||
* categories of key events:
|
||
*
|
||
* <p><em>"Key typed" events</em> are higher-level, and have already
|
||
* compensated for modifiers and keyboard layout to generate a single Unicode
|
||
* character. It may take several key press events to generate one key typed.
|
||
* The <code>getKeyCode</code> method will return <code>VK_UNDEFINED</code>,
|
||
* and <code>getKeyChar</code> will return a valid Unicode character or
|
||
* <code>CHAR_UNDEFINED</code>.
|
||
*
|
||
* <p><em>"Key pressed" and "key released" events</em> are lower-level, and
|
||
* are platform and keyboard dependent. They correspond to the actaul motion
|
||
* on a keyboard, and return a virtual key code which labels the key that was
|
||
* pressed. The <code>getKeyCode</code> method will return one of the
|
||
* <code>VK_*</code> constants (except VK_UNDEFINED), and the
|
||
* <code>getKeyChar</code> method is undefined.
|
||
*
|
||
* <p>Some keys do not generate key typed events, such as the F1 or HELP keys.
|
||
* Not all keyboards can generate all virtual keys, and no attempt is made to
|
||
* simulate the ones that can't be typed. Virtual keys correspond to the
|
||
* keyboard layout, so for example, VK_Q in English is VK_A in French. Also,
|
||
* there are some additional virtual keys to ease handling of actions, such
|
||
* as VK_ALL_CANDIDATES in place of ALT+VK_CONVERT. Do not rely on the value
|
||
* of the VK_* constants, except for VK_ENTER, VK_BACK_SPACE, and VK_TAB.
