Instances

Eq Event Source #
Methods (==) :: Event -> Event -> Bool # (/=) :: Event -> Event -> Bool #
Show Event Source #
Methods showsPrec :: Int -> Event -> ShowS # show :: Event -> String # showList :: [Event] -> ShowS #

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

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

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

onPos :: Event -> Maybe Position Source #

onWheel :: Event -> Maybe Int Source #

onSize :: Event -> Maybe Size Source #

onClose :: Event -> Maybe () Source #

onRefresh :: Event -> Maybe () Source #

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

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

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

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

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

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

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.
