Fields

_tickInfo_alreadyElapsed :: NominalDiffTime

Instances

Eq TickInfo

Ord TickInfo

tickLossy :: MonadWidget t m => NominalDiffTime -> UTCTime -> m (Event t TickInfo)

Special case of tickLossyFrom that uses the post-build event to start the tick thread.

tickLossyFrom

Arguments

:: MonadWidget t m

=> NominalDiffTime

-> UTCTime

-> Event t a

Event that starts a tick generation thread. Usually you want this to be something like the result of getPostBuild that only fires once. But there could be uses for starting multiple timer threads.

-> m (Event t TickInfo)

Send events over time with the given basis time and interval If the system starts running behind, occurrences will be dropped rather than buffered Each occurrence of the resulting event will contain the index of the current interval, with 0 representing the basis time

clockLossy :: MonadWidget t m => NominalDiffTime -> UTCTime -> m (Dynamic t TickInfo)

getCurrentTick :: NominalDiffTime -> UTCTime -> IO TickInfo

delay :: MonadWidget t m => NominalDiffTime -> Event t a -> m (Event t a)

Delay an Event's occurrences by a given amount in seconds.

debounce :: MonadWidget t m => NominalDiffTime -> Event t a -> m (Event t a)

Block occurrences of an Event until the given number of seconds elapses without the Event firing, at which point the last occurrence of the Event will fire.
