Methods

showsPrec :: Int -> Event -> ShowS

show :: Event -> String

showList :: [Event] -> ShowS

onKey :: Event -> Maybe (Key, KeyButtonState)

onChar :: Event -> Maybe (Char, KeyButtonState)

onButton :: Event -> Maybe (MouseButton, KeyButtonState)

onPos :: Event -> Maybe Position

onWheel :: Event -> Maybe Int

onSize :: Event -> Maybe Size

onClose :: Event -> Maybe ()

isKey :: Enum a => a -> Key -> Maybe ()

isChar :: Char -> Char -> Maybe ()

isButton :: MouseButton -> MouseButton -> Maybe ()

isPress :: (a, KeyButtonState) -> Maybe a

isRelease :: (a, KeyButtonState) -> Maybe a

registerTaskCallbacks :: (MonadIO m, MonadTask Event m) => IO (m ())

registerTaskCallbacks sets up all event callbacks, and returns a waitEvent equivalent function for task monad, which must be called repeatedly in order to pump events to other task co-routines.

These task co-routines should use watch to select event of interest, and they should be forked prior to the waitEvent call.
