Class UIKeyboardHIDUsage

  • public final class UIKeyboardHIDUsage
extends java.lang.Object
    This file defines a table of standardized key codes, called "HID usages" used by USB keyboards to identify individual keys. A general note on Usages and languages: Due to the variation of keyboards from language to language, it is not feasible to specify exact key mappings for every language. Where this list is not specific for a key function in a language, the closest equivalent key position should be used, so that a keyboard may be modified for a different language by simply printing different keycaps. One example is the Y key on a North American keyboard. In Germany this is typically Z. Rather than changing the keyboard firmware to put the Z Usage into that place in the descriptor list, the vendor uses the Y Usage on both the North American and German keyboards. This continues to be the existing practice in the industry, in order to minimize the number of changes to the electronics to accommodate other languages. The following constants are from the USB 'HID Usage Tables' specification, revision 1.1rc3.
