Props
element
- target event triggertarget
- additionally target event trigger, if specified with the element, will be used by all handlers to trigger the actiondelta
- minimal distance inpx
before a swipe startsdirectionDelta
- minimum distance inpx
required for the direction to be reversed while swiping.rotationAngle
- rotation anglemouseTrackingEnabled
- enable mouse trackingtouchTrackingEnabled
- enable touch trackingpreventDefaultTouchmoveEvent
- prevent default touch events while touchingpreventTrackingOnMouseleave
- triggeredonSwiped
callback when the event loses the element's focusonSwipeStart
- triggered on swipe start (if thedelta
is passed)onSwiping
- triggered during swipeonSwiped
- triggered after swipeonTap
- triggered when the swipe value is less than the minimum distance (delta
)
