Constructors

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 & Omit<HTMLAttributes<HTMLElement>, keyof 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 disabled(): boolean
  • Get/Set whether the expansion panel is disabled. Disabled panels are ignored for user interactions.

    Returns boolean

  • set disabled(v): void
  • Parameters

    • v: boolean

    Returns void

  • get nativeElement(): HTMLElement
  • Returns HTMLElement

  • get open(): boolean
  • Indicates whether the contents of the control should be visible.

    Returns boolean

  • set open(v): void
  • Parameters

    • v: boolean

    Returns void

Methods

  • 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.

    Parameters

    • nextProps: Readonly<P & Omit<HTMLAttributes<HTMLElement>, keyof P>>
    • nextContext: any

    Returns void

  • 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 & Omit<HTMLAttributes<HTMLElement>, keyof 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

  • 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 & Omit<HTMLAttributes<HTMLElement>, keyof P>>
    • prevState: Readonly<{}>

    Returns any

  • Hides the panel content.

    Returns boolean

  • Returns DOMElement<{
        children: any[];
        class: (P & Omit<HTMLAttributes<HTMLElement>, keyof P>)["className"];
        id: (P & Omit<HTMLAttributes<HTMLElement>, keyof P>)["id"];
        ref: ((ref) => void);
        style: {};
    }, any>
