A lot of them just have direct 40 * mappings (the function keys, arrow keys, etc.) so they aren't a problem. 41 * We had to do something a little funky to catch the keys on the numeric 42 * key pad (i.e. using event mask to distinguish between period on regular 43 * keyboard and decimal on keypad). We also have to do something incredibly 44 * hokey with regards to the shifted punctuation characters. For examples, 45 * consider '&' which is usually Shift-7. For the Java key typed events, 46 * that's no problem, we just say pass the unichar. But for the 47 * KeyPressed/Released events, we need to identify the virtual key code 48 * (which roughly correspond to hardware keys) which means we are supposed 49 * to say the virtual 7 key was pressed. But how are we supposed to know 50 * when we get a punctuation char what was the real hardware key was that 51 * was pressed? Although '&' often comes from Shift-7 the keyboard can be 52 * remapped! I don't think there really is a good answer, and hopefully 53 * all good applets are only interested in logical key typed events not 54 * press/release. Meanwhile, we are hard-coding the shifted punctuation 55 * to trigger the virtual keys that are the expected ones under a standard 56 * keymapping. Looking at Windows & Mac, they don't actually do this, the 57 * Mac seems to just put the ascii code in for the shifted punctuation 58 * (which means they actually end up with bogus key codes on the Java side), 59 * Windows I can't even figure out what it's doing. 60 */ 61#define KL_STANDARD java_awt_event_KeyEvent_KEY_LOCATION_STANDARD 62#define KL_NUMPAD
