KeyEvent Delivery
Key events are delivered in the following order:
# | Event Type | Constraints | Notes |
---|---|---|---|
1 | EVENT_KEY_PRESSED | excluding auto-repeat -modifier keys | |
2 | EVENT_KEY_RELEASED | excluding auto-repeat -modifier keys |
Besides regular modifiers like InputEvent.SHIFT_MASK
etc.,
the InputEvent.AUTOREPEAT_MASK
bit is added if repetition is detected, following above constraints.
Auto-Repeat shall behave as follow:
P = pressed, R = released 0 = normal, 1 = auto-repeat P(0), [ R(1), P(1), R(1), ..], R(0)The idea is if you mask out auto-repeat in your event listener you just get one long pressed P/R tuple for
printable
and Action
keys.
Action
keys will produce pressed
and released
events including auto-repeat
.
Printable
keys will produce pressed
and released
events.
Modifier
keys will produce pressed
and released
events
excluding auto-repeat
.
They will also influence subsequent event's modifier
bits while pressed.
Key-chars
, as well as
printable
key-codes
and key-symbols
use the UTF-16 unicode space w/o collision.
Non-printable
key-codes
and key-symbols
,
i.e. modifier-
and action-
keys,
are mapped to unicode's control and private range and do not collide w/ printable
unicode values
with the following exception.
The following Key-code
s and key-symbol
s collide w/ unicode space:
unicode range | virtual key code | unicode character |
---|---|---|
[0x61 .. 0x78] | [VK_F1 ..VK_F24 ] | ['a'..'x'] |
Collision was chosen for Key-code
and key-symbol
mapping
to allow a minimal code range, i.e. [0..255]
.
The reduced code range in turn allows the implementation to utilize fast and small lookup tables,
e.g. to implement a key-press state tracker.

public static KeyEvent create(short eventType, Object source, long when, int modifiers, short keyCode, short keySym, char keyChar)
public final char getKeyChar()
key symbol
incl. active modifiers
.
getKeySymbol()
,
getKeyCode()
public final short getKeySymbol()
For printable keys
, the key symbol is the unmodified
representation of the UTF-16 key char
.
E.g. symbol [VK_A
, 'A'] for char 'a'.
isPrintableKey()
,
getKeyChar()
,
getKeyCode()
public final short getKeyCode()
In contrast to key symbol
, key code
uses a fixed US keyboard layout and therefore is keyboard layout independent.
E.g. virtual key code VK_Y
denotes the same physical key
regardless whether keyboard layout QWERTY
or
QWERTZ
is active. The key symbol
of the former is
VK_Y
, where the latter produces VK_Y
.

- UTF16 value to map. It is expected that the incoming keyChar value is unshifted and unmodified,
however, lower case a-z is mapped to VK_A
- VK_Z

virtual key (VK) value.public static boolean isModifierKey(short vKey)
true
if the given virtualKey
represents a modifier key, otherwise false
.
A modifier key is one of VK_SHIFT
, VK_CONTROL
, VK_ALT
, VK_ALT_GRAPH
, VK_META
.
public static int getModifierMask(short vKey)
vKey
is a modifier key
, method returns the corresponding modifier mask,
otherwise 0.
public final boolean isModifierKey()
true
if key symbol
represents a modifier key,
otherwise false
.
See isModifierKey(short)
for details.
Note: Implementation uses a cached value.
public final boolean isActionKey()
true
if key symbol
represents a non-printable and
non-modifier
action key, otherwise false
.
Hence it is the set A of all keys U w/o printable P and w/o modifiers M:
A = U - ( P + M )

public static boolean isPrintableKey(short uniChar, boolean isKeyChar)
true
if given uniChar
represents a printable character,
i.e. a value other than VK_UNDEFINED
and not a control or non-printable private code.
A printable character is neither a modifier key
, nor an action key
.
Otherwise returns false
.
Distinction of key character and virtual key code is made due to unicode collision.

A printable character is neither a modifier key
