Description

All types.

Synopsis

Documentation

data State #

Key processing state.

Constructors

State
Fields stateModifiers :: !(Set Key) Perhaps on some systems order of key press matters, but this type assumes it doesn't. stateCombos :: !(Seq Combo) A sequence of key combinations e.g. "a" "C-f", "Alt-DEL", etc.

data Combo #

A combination of some modifiers and a key.

Constructors

Combo !(Set Key) !Key

Instances

Methods showsPrec :: Int -> Combo -> ShowS # show :: Combo -> String # showList :: [Combo] -> ShowS #

data Event #
