创建具有特定字段的KeyEvent

Question

我将如何去改变生成的KeyEvent的字段？从键盘

java.awt.event.KeyEvent[KEY_PRESSED, 
keyCode=65, 
keyText=A, 
keyChar='a', 
keyLocation=KEY_LOCATION_STANDARD, 
rawCode=65, 
primaryLevelUnicode=97, 
scancode=30, 
extendedKeyCode=0x41] on panel0 

实际KeyEvent的生成的KeyEvent

java.awt.event.KeyEvent[KEY_PRESSED, 
keyCode=65, 
keyText=A, 
keyChar='a', 
keyLocation=KEY_LOCATION_STANDARD, 
rawCode=0, 
primaryLevelUnicode=0, 
scancode=0, 
extendedKeyCode=0x0] on panel0 

new KeyEvent(component, KeyEvent.KEY_PRESSED, System.currentTimeMillis(), 0, 65, 'a') 

差异

rawCode 
primaryLevelUnicode 
scancode 
extendedKeyCode 

有没有一种方法我可以设置的KeyEvent对象上这些领域？

Answer 1

望着在KeyEvent类的源代码，看来你不能设置这些：

//set from native code. 
private transient long rawCode = 0; 
private transient long primaryLevelUnicode = 0; 
private transient long scancode = 0; // for MS Windows only 
private transient long extendedKeyCode = 0; 

这是私人的，并从本地代码（所以在Java中没有变化）设置。
