KeyEvent介绍

[英]Describes the state of a key - either it has been pressed or it has been released. Also keeps track of which character the event corresponds to - the difference between a key and a character is that a key corresponds to a physical key on the keyboard, whereas the character is the character that a keypress combination represents. Keys are universal and mapped into the Key enum, whereas characters can be any char value. Some examples of the differences:

  • On almost any keyboard, pressing Key#EIGHT results in the character '8'.
  • On an English keyboard, pressing Key#EIGHT when the Key#LSHIFT is down leads to the character '*'.
  • On a Swedish keyboard, pressing Key#EIGHT when the Key#LSHIFT is down leads to the character '('.
    [中]描述按键的状态-按键已按下或已释放。还跟踪事件对应的字符-键和字符之间的区别在于键对应于键盘上的物理键，而字符是按键组合表示的字符。键是通用的并映射到键枚举中，而字符可以是任何字符值。差异的一些例子：
    *几乎在任何键盘上，按#8键都会生成字符“8”。
    在英文键盘上，当#LSHIFT键按下时，按#8键将显示字符“”。
    *在瑞典键盘上，当“LSHIFT”键按下时，按“EIGHT”键可显示字符“（”。
