Properties

idPrefix live? values

Methods

custom? onChange unavailable?

Properties

idPrefix

idPrefix: string

Prefix for element ids, so two forms in one document never share one.

Optionallive

live?: boolean

Emit colour and slider edits on input as well as change, for a dialog that previews live. Off, a colour is one edit when the picker closes and a slider one edit on release, which is what a per-edit undo history wants.

values

values: Readonly<Record<string, unknown>>

Methods

Optionalcustom

  • custom(control: FormControl, row: HTMLElement): null | HTMLElement

  • Renders the control column of a custom row. Null skips the row.

    Parameters

    Returns null | HTMLElement

onChange

  • onChange(key: string, value: unknown): void

  • Every edit, with the value in the control's declared type.

    Parameters

    • key: string
    • value: unknown

    Returns void

Optionalunavailable

  • unavailable(key: string, option?: string): null | string

  • Why a control, or one option of a select, cannot act right now, or null when it can. Drawn disabled with the reason as its title, never hidden: a greyed row is information, an absent one is a mystery.

    Parameters

    • key: string
    • Optionaloption: string

    Returns null | string
