KeyEvent介绍

KeyEvent Delivery

](https://www.tabnine.com/code/java/classes/com.jogamp.newt.event.KeyEvent#) Key events are delivered in the following order:

#Event TypeConstraintsNotes1#EVENT_KEY_PRESSED excluding #isAutoRepeat()- #isModifierKey() keys2#EVENT_KEY_RELEASED excluding #isAutoRepeat()- #isModifierKey() keys

In case the native platform does not deliver keyboard events in the above order or skip events, the NEWT driver will reorder and inject synthetic events if required.

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 #isPrintableKey() and #isActionKey() keys.

#isActionKey() keys will produce #EVENT_KEY_PRESSEDand #EVENT_KEY_RELEASED events including #isAutoRepeat().

#isPrintableKey() keys will produce #EVENT_KEY_PRESSED and #EVENT_KEY_RELEASED events.

#isModifierKey() keys will produce #EVENT_KEY_PRESSED and #EVENT_KEY_RELEASED events excluding #isAutoRepeat(). They will also influence subsequent event's #getModifiers() bits while pressed.

Unicode Mapping

](https://www.tabnine.com/code/java/classes/com.jogamp.newt.event.KeyEvent#)

#getKeyChar(), as well as #isPrintableKey() #getKeyCode() and #getKeySymbol()use the UTF-16 unicode space w/o collision.

Non- #isPrintableKey() #getKeyCode() and #getKeySymbol(), i.e. #isModifierKey() and #isActionKey()keys, are mapped to unicode's control and private range and do not collide w/ #isPrintableKey() unicode values with the following exception.
[

Unicode Collision

](https://www.tabnine.com/code/java/classes/com.jogamp.newt.event.KeyEvent#)

The following #getKeyCode()s and #getKeySymbol()s collide w/ unicode space:

unicode rangevirtual key codeunicode character[0x61 .. 0x78][ #VK_F1.. #VK_F24]['a'..'x']

Collision was chosen for #getKeyCode() and #getKeySymbol() 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.

KeyEvent Delivery

](https://www.tabnine.com/code/java/classes/com.jogamp.newt.event.KeyEvent#)密钥事件按以下顺序传递：
#事件类型ConstraintsNotes1#事件#按键#不包括#isAutoRepeat（）-#isModifierKey（）按键2#事件#按键#不包括#isAutoRepeat（）-#isModifierKey（）按键
如果本机平台未按上述顺序交付键盘事件或跳过事件，则NEWT驱动程序将根据需要重新排序并注入合成事件。
除了常规修饰符（如InputEvent#SHIFT#U MASK等）外，如果检测到重复，将根据上述约束添加InputEvent#AUTOREPEAT#MASK位。
自动重复应如下所示：

P = pressed, R = released 
0 = normal, 1 = auto-repeat 
P(0), [ R(1), P(1), R(1), ..], R(0)

如果您在事件侦听器中屏蔽了自动重复，您只需为#isPrintableKey（）和#isActionKey（）键获得一个长按的P/R元组。
#isActionKey（）键将产生#事件#键#按和#事件#键#释放的事件，包括#isAutoRepeat（）。
#isPrintableKey（）键将产生#事件#键被按下和#事件#键被释放事件。
#isModifierKey（）键将产生#事件#键#按下和#事件#键#释放的事件，不包括#isAutoRepeat（）。按下时，它们还会影响后续事件的#getModifiers（）位。
[

Unicode Mapping

](https://www.tabnine.com/code/java/classes/com.jogamp.newt.event.KeyEvent#)
#getKeyChar（）以及#isPrintableKey（）#getKeyCode（）和#getKeySymbol（）使用UTF-16 unicode空间，不存在冲突。
非#isPrintableKey（）#getKeyCode（）和#getKeySymbol（），即#isModifierKey（）和#isActionKey（）键，映射到unicode的控件和专用范围，不会与w/#isPrintableKey（）unicode值冲突，但以下情况除外。
[

Unicode Collision

](https://www.tabnine.com/code/java/classes/com.jogamp.newt.event.KeyEvent#)
以下#getKeyCode（）和#getKeySymbol（）与unicode空间冲突：
unicode范围虚拟键代码unicode字符[0x61..0x78][#VK_F1..VK_F24]['a'..'x']
为#getKeyCode（）和#getKeySymbol（）映射选择了冲突，以允许最小的代码范围，即[0$]。减少的代码范围反过来允许实现利用快速和小的查找表，例如实现按键状态跟踪器。
