    Returns IgrRating<P>

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}</>;
}
}

    Returns string

  • set label(v): void
  • Parameters

    • v: string

    Returns void

  • get max(): number
  • The maximum value for the rating. If there are projected symbols, the maximum value will be resolved based on the number of symbols.

    Returns number

  • set max(v): void
  • Parameters

  • Makes the control a readonly field.

    Returns boolean

  • set readOnly(v): void
  • Parameters

    • v: boolean

    Returns void

  • get readonly(): boolean
  • Sets the readonly state of the component

    Deprecated

    Use the readOnly property instead.

    Returns boolean

  • set readonly(v): void
  • Parameters

    • v: boolean

    Returns void

  • get single(): boolean
  • Toggles single selection visual mode.

    Returns boolean

  • set single(v): void
  • Parameters

    Returns number

  • set step(v): void
  • Parameters

    • v: number

    Returns string

  • set valueFormat(v): void
  • Parameters

    • v: string

    Returns void

Methods

  • Checks for validity of the control and emits the invalid event if it invalid.

    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>
    • 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

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

  • Checks for validity of the control and shows the browser message if it invalid.

    Returns void

  • Sets a custom validation message for the control. As long as message is not empty, the control is considered invalid.

    Returns void

  • Parameters

    • element: any
