public class KeyEvent extends InputEvent
Besides regular modifiers like InputEvent.SHIFT_MASK
etc.,
the InputEvent.AUTOREPEAT_MASK
bit is added if repetition is detected.
Auto-Repeat shall behave as follow:
D = pressed, U = released, T = typed 0 = normal, 1 = auto-repeat D(0), [ U(1), T(1), D(1), U(1) T(1) ..], U(0) T(0)The idea is if you mask out auto-repeat in your event listener you just get one long pressed key D/U/T triple.
Modifiers keys
will produce regular events (pressed, released and typed),
however they will not produce Auto-Repeat events itself.
