Properties

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>
props: Readonly<P> & Readonly<{
    children?: ReactNode;
}>
refs: {
    [key: string]: ReactInstance;
}

Type declaration

  • [key: string]: ReactInstance
state: Readonly<{}>
contextType?: Context<any>

If set, this.context will be set at runtime to the current value of the given Context.

Usage:

type MyContext = number
const Ctx = React.createContext<MyContext>(0)

class Foo extends React.Component {
static contextType = Ctx
context!: React.ContextType<typeof Ctx>
render () {
return <>My context's value: {this.context}</>;
}
}

Accessors

  • get actualPixelScalingRatio(): number
  • Gets the actual pixel scaling ratio used to affect the pixel density of the control. A higher scaling ratio will produce crisper visuals at the expense of memory. Lower values will cause the control to appear blurry.

    Returns number

  • set actualPixelScalingRatio(v): void
  • Parameters

    • v: number

    Returns void

  • get iconColor(): string
  • Gets or sets the color of the indicator.

    Returns string

  • set iconColor(v): void
  • Parameters

    • v: string

    Returns void

  • get isAnimationEnabled(): boolean
  • Gets or sets whether animations are enabled.

    Returns boolean

  • set isAnimationEnabled(v): void
  • Parameters

    • v: boolean

    Returns void

  • get isExpanded(): boolean
  • Gets or sets the expansion state of the indicator.

    Returns boolean

  • set isExpanded(v): void
  • Parameters

    • v: boolean

    Returns void

  • get nativeElement(): HTMLElement
  • Returns HTMLElement

  • get pixelScalingRatio(): number
  • Gets or sets the scaling value used to affect the pixel density of the control. A higher scaling ratio will produce crisper visuals at the expense of memory. Lower values will cause the control to appear blurry.

    Returns number

  • set pixelScalingRatio(v): void
  • Parameters

    • v: number

    Returns void

Methods

  • Catches exceptions generated in descendant components. Unhandled exceptions will cause the entire component tree to unmount.

    Parameters

    • error: Error
    • errorInfo: ErrorInfo

    Returns void

  • Returns void

  • Called immediately after updating occurs. Not called for the initial render.

    The snapshot is only present if getSnapshotBeforeUpdate is present and returns non-null.

    Parameters

    • prevProps: Readonly<P>
    • prevState: Readonly<{}>
    • Optional snapshot: any

    Returns void

  • Called immediately before a component is destroyed. Perform any necessary cleanup in this method, such as cancelled network requests, or cleaning up any DOM elements created in componentDidMount.

    Returns void

  • Parameters

    • name: string

    Returns any

  • Parameters

    • Optional callback: (() => void)
        • (): void
        • Returns void

    Returns void

  • 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

    • prevProps: Readonly<P>
    • prevState: Readonly<{}>

    Returns any

  • Parameters

    • width: number
    • height: number

        • (): void
        • Returns void

    Returns void

  • Parameters

    • nextProps: any
