• Optional activePosition: TooltipPosition

context#

• context: any

If using the new style context, re-declare this in your class to be the React.ContextType of your static contextType. Should be used with type annotation or static contextType.

static contextType = MyContext
// For TS pre-3.7:
context!: React.ContextType<typeof MyContext>
// For TS 3.7 and above:
declare context: React.ContextType<typeof MyContext>

Methods#

UNSAFE_componentWillMount#

▸ Optional UNSAFE_componentWillMount(): void

Called immediately before mounting occurs, and before Component#render. Avoid introducing any side-effects or subscriptions in this method.

This method will not stop working in React 17.

Note: the presence of getSnapshotBeforeUpdate or getDerivedStateFromProps prevents this from being invoked.

deprecated 16.3, use componentDidMount or the constructor instead

see - https://reactjs.org/blog/2018/03/27/update-on-async-rendering.html#initializing-state - https://reactjs.org/blog/2018/03/27/update-on-async-rendering.html#gradual-migration-path

Returns#

void

Inherited from#

React.Component.UNSAFE_componentWillMount

UNSAFE_componentWillReceiveProps#

▸ Optional UNSAFE_componentWillReceiveProps(nextProps, nextContext): void

Called when the component may be receiving new props. React may call this even if props have not changed, so be sure to compare new and existing props if you only want to handle changes.

Calling Component#setState generally does not trigger this method.

This method will not stop working in React 17.

Note: the presence of getSnapshotBeforeUpdate or getDerivedStateFromProps prevents this from being invoked.

deprecated 16.3, use static getDerivedStateFromProps instead

UNSAFE_componentWillUpdate#

▸ Optional UNSAFE_componentWillUpdate(nextProps, nextState, nextContext): void

Note: You cannot call Component#setState here.

This method will not stop working in React 17.

Note: the presence of getSnapshotBeforeUpdate or getDerivedStateFromProps prevents this from being invoked.

deprecated 16.3, use getSnapshotBeforeUpdate instead

getSnapshotBeforeUpdate#

▸ Optional getSnapshotBeforeUpdate(prevProps, prevState): any

Runs before React applies the result of render to the document, and returns an object to be given to componentDidUpdate. Useful for saving things such as scroll position before render causes changes to it.

Note: the presence of getSnapshotBeforeUpdate prevents any of the deprecated lifecycle events from running.

Parameters#

Name	Type
`prevProps`	`Readonly`<`TooltipProps`>
`prevState`	`Readonly`<{}>

Returns#

any

onLeaveTarget#

▸ Protected onLeaveTarget(): void

Returns#

refreshPosition#

▸ refreshPosition(): void

Returns#

void

render#

▸ render(): null | Element

Returns#

Overrides#

React.Component.render

setPosition#

▸ Protected setPosition(elem, pos): void

Parameters#

`elem`	`HTMLDivElement`
`pos`	`Object`
`pos.left`	`number`
`pos.top`	`number`

Returns#

void

setState#

▸ setState<K>(state, callback?): void

Type parameters#

Name	Type
`K`	extends `never`

Parameters#

Name	Type
`state`	`null` \| {} \| (`prevState`: `Readonly`<{}>, `props`: `Readonly`<`TooltipProps`>) => `null` \| {} \| `Pick`<{}, `K`> \| `Pick`<{}, `K`>

Returns#

void

Inherited from#

React.Component.setState

shouldComponentUpdate#

▸ Optional shouldComponentUpdate(nextProps, nextState, nextContext): boolean

Called to determine whether the change in props and state should trigger a re-render.

Component always returns true. PureComponent implements a shallow comparison on props and state and returns true if any props or states have changed.

If false is returned, Component#render, componentWillUpdate and componentDidUpdate will not be called.

Parameters#

Name	Type
`nextProps`	`Readonly`<`TooltipProps`>
`nextState`	`Readonly`<{}>
`nextContext`	`any`

Returns#

boolean
