KeyEvent中有多少个Java KeyCode？

Question

How many codes can be returned by KeyEvent.getKeyCode()?

What is the range of the codes returned by KeyEvent.getKeyCode()?

Are the KeyCodes listed on the javadoc for KeyEvent (VK_?) the only KeyCodes that can be returned, or are there more?

Answer 1

It doesn't look like there are any such guarantees, judging by this paragraph from the documentation:

WARNING: Aside from those keys that are defined by the Java language (VK_ENTER, VK_BACK_SPACE, and VK_TAB), do not rely on the values of the VK_ constants. Sun reserves the right to change these values as needed to accomodate a wider range of keyboards in the future.

Answer 2

这些都是可以由Key *方法返回的所有KeyCode。
