37 * Table to map typed characters to their Java virtual key equivalent and back.
38 * We use the incoming unichar (ignoring all modifiers) and try to figure out
39 * which virtual key code is appropriate. 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.
