API Reference

Pannable

Pannable provides a pan gesture simulation on recent mobile browsers for iOS and Android. It can also be used on mouse-base devices across on all evergreen browsers.

type Point = { x: number, y: number };
type PanEvent = {
  translation: Point,
  velocity: Point,
  target: HTMLElement,
};

Prop Types

Property	Type	DefaultValue	Description
enabled	boolean	true	Indicate whether the gesture listener is enabled. If you change this property to false while the gesture is listening, the gesture transitions to cancel.
shouldStart	boolean,function	true	Whether to start gesture listening. : (evt: PanEvent) => void
onStart	function	() => {}	Callback invoked when the gesture starts listening.: (evt: PanEvent) => void
onMove	function	() => {}	Callback invoked when the gesture moves.: (evt: PanEvent) => void
onEnd	function	() => {}	Callback invoked when the gesture ended listening.: (evt: PanEvent) => void
onCancel	function	() => {}	Callback invoked when the gesture cancelled.: (evt: PanEvent) => void

Pad

Pad provides a scrollable content component on which overflow scrollbars are not natively supported. It also provides paging scroll implementation and multiple content layout mode.

type Point = { x: number, y: number };
type Size = { width: number, height: number };
type PadEvent = {
  contentOffset: Point,
  contentVelocity: Point,
  dragging: boolean,
  decelerating: boolean,
  size: Size,
  contentSize: Size,
};

Prop Types

Property	Type	DefaultValue	Description
children	element,Component	null	Rendered content. Can be a react component class, a render function, or a rendered element.:(pad: Pad) => element
width	number	0	The width of the bounding view.
height	number	0	The height of the bounding view.
contentWidth	number	0	The width of the content view.
contentHeight	number	0	The height of the content view.
scrollEnabled	boolean	true	Determines whether scrolling is enabled.
pagingEnabled	boolean	false	Determines whether paging is enabled.
directionalLockEnabled	boolean	false	determines whether scrolling is disabled in a particular direction.
onScroll	function	() => {}	Callback invoked when the content view scrolls.:({evt: PadEvent}) => void

Public Methods

scrollTo({ offset: Point, animated: boolean })

type Size = { width: number, height: number };

Prop Types

Property	Type	DefaultValue	Description
width	number	-1	The width of the content. If you set this property to -1, it shrinks the content's width.
height	number	-1	The height of the content. If you set this property to -1, it shrinks the content's height.
