poll	back to summary
pack-priv void poll(ByteBuffer keyDownBuffer)

putEvent	back to summary
private void putEvent(int keycode, byte state, int ch, long millis, boolean repeat)

read	back to summary
pack-priv void read(ByteBuffer buffer)

releaseAll	back to summary
pack-priv void releaseAll(long millis) This is called when the window loses focus: we release all currently pressed keys. If a key has been pressed (or hasn't been released at all), before we regain focus, we'll start receiving repeat press events. We'll treat the first of those as a non-repeat press.

ToAscii	back to summary
