Signals
down

Type for the callback on the (unwrapped) C side.
type GestureStylusDownCallback = Double -> Double -> IO () Source #
No description available in the introspection data.
afterGestureStylusDown :: (IsGestureStylus a, MonadIO m) => a -> GestureStylusDownCallback -> m SignalHandlerId Source #
Connect a signal handler for the down signal, to be run after the default handler. When overloading is enabled, this is equivalent to
after gestureStylus #down callback

A convenience synonym for Nothing :: Maybe GestureStylusDownCallback
onGestureStylusDown :: (IsGestureStylus a, MonadIO m) => a -> GestureStylusDownCallback -> m SignalHandlerId Source #
