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