Accessors

aiDescription

Get Signature

get aiDescription(): string | null

Defined in: js-api/src/u2core/component.ts:337

A short AI-facing briefing, seeded from the registry's usage or description.

Returns

string | null

Set Signature

set aiDescription(x): void

Defined in: js-api/src/u2core/component.ts:341

Parameters

Parameter	Type
`x`	`string` \| `null`

Returns

void

Inherited from

ColumnGrid.aiDescription

ambientAdoption

Get Signature

get protected ambientAdoption(): boolean

Defined in: js-api/src/widgets/base.ts:278

A widget wrapper minted inside somebody's effect scope must not be auto-disposed with it.

Returns

boolean

Overrides

Control.ambientAdoption

children

Get Signature

get children(): Widget<any>[]

Defined in: js-api/src/widgets/base.ts:313

Parent widget up the DOM tree, or null.

Returns

Widget<any>[]

name

Get Signature

get name(): string | undefined

Defined in: js-api/src/u2core/component.ts:882

A named control carries its name in the DOM: data-u2-name is the stable automation id selectors, tutorials and agents address the control by — the same attribute the spec renderer stamps on named nodes, so hand-built and spec-built UI share one selector vocabulary. Derived names (an input's label fallback) never stamp — see Component.deriveName.

Returns

string | undefined

Set Signature

set name(x): void

Defined in: js-api/src/u2core/component.ts:886

Unique within a spec: the anchor for selection, patches and automation. An accessor pair (not a field), so a platform descendant's own name accessors override it legally (TS2611).

Parameters

Parameter	Type
`x`	`string` \| `undefined`

Returns

void

Inherited from

ColumnGrid.name

parent

Get Signature

get parent(): Widget<any> | null

Defined in: js-api/src/widgets/base.ts:310

Parent widget up the DOM tree, or null.

Returns

Widget<any> | null

propertyTarget

Get Signature

get propertyTarget(): unknown

Defined in: js-api/src/u2core/component.ts:435

What this component's properties are read from and written to — prop.get(target) / prop.set(target, v): the component itself, unless an adoption says otherwise.

Returns

unknown

Inherited from

Control.propertyTarget

propertyTier

Get Signature

get propertyTier(): boolean

Defined in: js-api/src/widgets/base.ts:282

Every property getProperties declares is a bind step, read and written on propertyTarget.

Returns

boolean

Overrides

Control.propertyTier

root

Get Signature

get root(): HTMLElement

Defined in: js-api/src/u2core/component.ts:675

Returns

HTMLElement

Set Signature

set root(x): void

Defined in: js-api/src/u2core/component.ts:679

Parameters

Parameter	Type
`x`	`HTMLElement`

Returns

void

Inherited from

Control.root

rootId

Get Signature

get rootId(): string

Defined in: js-api/src/u2core/component.ts:704

Stable element id, minted (u2-<n>) on first ask unless the root has one: the anchor of for, aria-* and data-u2-owner-id references.

Returns

string

Inherited from

Control.rootId

scope

Get Signature

get scope(): Scope

Defined in: js-api/src/u2core/component.ts:86

Minted on first use; assigned before _scopeMinted fires, so the hook's own this.scope.own(...) reads the stored scope instead of re-entering the mint. Lazy: counted and tracked only once it owns something, so a static control costs nothing.

Returns

Scope

Inherited from

Control.scope

type

Get Signature

get type(): string

Defined in: js-api/src/widgets/base.ts:209

Widget type name; subclasses override it.

Returns

string

visible

Get Signature

get visible(): boolean

Defined in: js-api/src/u2core/component.ts:694

Hidden ⇔ the root carries the hidden attribute.

Returns

boolean

Set Signature

set visible(x): void

Defined in: js-api/src/u2core/component.ts:698

Parameters

Parameter	Type
`x`	`boolean`

Returns

void

Inherited from

Control.visible

Methods

_notifyPropertyChange()

protected _notifyPropertyChange(p): void

Defined in: js-api/src/widgets/base.ts:360

Notifies the property tier. Called from both the addProperty setter (overrides that skip super would otherwise lose props.x = writes) and onPropertyChanged (direct calls); the double notify collapses into one microtask refresh.

Parameters

Parameter	Type
`p`	`Property` \| `null`

Returns

void

_ownPropertyChanges()

protected _ownPropertyChanges(): ObservableLike<PropertyChange>

Defined in: js-api/src/widgets/base.ts:365

Returns

ObservableLike<PropertyChange>

_scopeMinted()

protected _scopeMinted(_scope): void

Defined in: js-api/src/widgets/base.ts:329

First-mint hook: a platform descendant wires its lifecycle here. Never fired for a scope provided to init — that path runs inside the constructor chain.

Parameters

Parameter	Type
`_scope`	`Scope`

Returns

void

Overrides

Control._scopeMinted

_wireDartLifecycle()

protected _wireDartLifecycle(): void

Defined in: js-api/src/widgets/base.ts:345

Dart-owned lifecycle: the platform kill disposes the scope, and disposing the scope kills the widget through the kill-walk.

Returns

void

_wireJsLifecycle()

protected _wireJsLifecycle(): void

Defined in: js-api/src/widgets/base.ts:336

JS-owned lifecycle: disposing the scope detaches the widget, and vice versa.

Returns

void

_wireLifecycle()

protected _wireLifecycle(): void

Defined in: js-api/src/widgets/base.ts:331

Returns

void

accessibleLabel()

protected accessibleLabel(): string | undefined

Defined in: js-api/src/u2core/component.ts:762

The accessible name: aria-label, then the aria-labelledby texts, then this control's own data-u2-part="label" element, then — for a root that is a button — its own text.

Returns

string | undefined

Inherited from

Control.accessibleLabel

addProperty()

addProperty(propertyName, propertyType, defaultValue?, options?): any

Defined in: js-api/src/widgets/base.ts:388

Registers an property with the specified type, name, and defaultValue.

Parameters

Parameter	Type	Default value	Description
`propertyName`	`string`	`undefined`	-
`propertyType`	`"string"` \| `"bigint"` \| `"object"` \| `"map"` \| `"file"` \| `"bool"` \| `"int"` \| `"double"` \| `"byte_array"` \| `"datetime"` \| `"qnum"` \| `"dataframe"` \| `"num"` \| `"string_list"` \| `"dataframe_list"` \| `"cell"` \| `"column"` \| `"column_list"` \| `"graphics"` \| `"blob"` \| `"tablerowfiltercall"` \| `"colfiltercall"` \| `"bitset"` \| `"dynamic"` \| `"viewer"` \| `"list"` \| `"semantic_value"` \| `"func"` \| `"funccall"` \| `"property"` \| `"categorical"` \| `"numerical"` \| `"GridCellRenderArgs"` \| `"element"` \| `"view"` \| `"TableView"` \| `"User"` \| `"Menu"` \| `"Project"` \| `"event_data"` \| `"progressindicator"` \| `"Credentials"` \| `"ScriptEnvironment"` \| `"Notebook"`	`undefined`	-
`defaultValue`	`any`	`null`	-
`options`	`object` & `IProperty` \| `null`	`null`	-

Returns

any

See

Registered property gets added to properties. Returns default value, thus allowing to combine registering a property with the initialization

options.get/options.set override how the property reads/writes (instead of the default fieldName field access); the change notification (onPropertyChanged) always fires on write, and a {get}-only options yields a custom read with the default fieldName write.

addStatusProvider()

addStatusProvider(name, provider): void

Defined in: js-api/src/widgets/base.ts:468

Adds live parts, hit areas and readings to this widget's status. Providers run in registration order on every read; an existing name is replaced in place, and later providers override earlier entries. Coordinates use the widget's own hit-area system. Detaching the widget removes all providers. A subclass that overrides getWidgetStatus composes with super.getWidgetStatus().

Parameters

Parameter	Type	Description
`name`	`string`	Stable name of the component contributing the status.
`provider`	`StatusProvider`	Computes the contribution each time the status is requested.

Returns

void

Example

widget.addStatusProvider('selection', () => ({values: {'selected rows': table.selection.trueCount}}));
console.log(widget.getWidgetStatus().values?.['selected rows']);
widget.removeStatusProvider('selection');
see samples/grid/custom-renderer-status

apply()

apply(properties): Widget

Defined in: js-api/src/widgets/base.ts:267

Sets each key of properties as the property of that name; returns this widget.

Parameters

Parameter	Type
`properties`	`object`

Returns

Widget

bindProps()

bindProps(): BindProp[]

Defined in: js-api/src/u2core/component.ts:492

The signal-backed subset of the meta props — what a binding picker offers on a named node — plus, under propertyTier, every declared property. Allocates no signal.

Returns

BindProp[]

Inherited from

Control.bindProps

bindStep()

bindStep(name): Signal<unknown> | BindSource | null

Defined in: js-api/src/u2core/component.ts:481

One binding step (DD5): a meta-declared prop's same-named Signal member — a named node is a bind source, generated off componentMeta the way getProperties is — then, under propertyTier, a cached signal over the declared property. '' answers the default binding: the component's own value signal, where one exists.

Parameters

Parameter	Type
`name`	`string`

Returns

Signal<unknown> | BindSource | null

Inherited from

Control.bindStep

deriveName()

protected deriveName(x): void

Defined in: js-api/src/u2core/component.ts:109

Sets the introspection/form key without claiming an automation id — the label-fallback path: a caption is not a stable identity, so it never reaches data-u2-name.

Parameters

Parameter	Type
`x`	`string` \| `undefined`

Returns

void

Inherited from

Control.deriveName

detach()

detach(): void

Defined in: js-api/src/widgets/base.ts:317

Gets called when a widget is detached and will no longer be used. Typically used for unsubscribing from events. Be sure to call super.detach() if this method is overridden.

Returns

void

dispose()

dispose(): void

Defined in: js-api/src/u2core/component.ts:687

Disposes the control; disposed by hand, it also leaves the page — a dead control left on show looks alive. One its owner disposes leaves the DOM to whoever holds it: a region swapping its content, a spec re-rendering.

Returns

void

Inherited from

Control.dispose

effect()

effect(fn): this

Defined in: js-api/src/u2core/component.ts:260

Runs fn now and on every change of the signals it reads, until this component is disposed. Called while a row of each() or an effect run is being built, it belongs on a control built there (input.effect(...)) — on a longer-lived one it piles up with every rebuild, and u2 warns.

Parameters

Parameter	Type
`fn`	() => `void`

Returns

this

Inherited from

Control.effect

fireEvent()

protected fireEvent(eventId, args?): void

Defined in: js-api/src/u2core/component.ts:636

Every matching listener runs inside one batch; a throwing one is reported to this component's scope and does not stop the rest.

Parameters

Parameter	Type
`eventId`	`string`
`args?`	`unknown`

Returns

void

Inherited from

Control.fireEvent

getDartProperties()

getDartProperties(): any[]

Defined in: js-api/src/widgets/base.ts:296

Dart handles of the properties that have one.

Returns

any[]

getFunctions()

getFunctions(): Func[]

Defined in: js-api/src/widgets/base.ts:289

Functions that are applicable to this particular widget. Used in the UI to display context actions, and for the AI integrations.

Returns

Func[]

Overrides

Control.getFunctions

getItems()

getItems(_opts?): IItemsState | undefined

Defined in: js-api/src/u2core/component.ts:737

Items of a collection-like control; undefined for other kinds. list holds the first ITEMS_CAP unless all.

Parameters

Parameter	Type
`_opts?`	{ `all?`: `boolean`; }
`_opts.all?`	`boolean`

Returns

IItemsState | undefined

Inherited from

Control.getItems

getProperties()

getProperties(): Property[]

Defined in: js-api/src/widgets/base.ts:285

Returns all properties of this widget: the meta-generated ones plus addProperty's.

Returns

Property[]

Overrides

Control.getProperties

getState()

getState(): IControlState

Defined in: js-api/src/u2core/component.ts:713

The state block generic tests read (DG.U2.state). This base reads the DOM — kind, name, accessible name, aria-disabled, hidden, focus, aria-busy — plus getItems; a subclass adds what the DOM cannot say and spreads super.getState(). Synchronous, side-effect free, never cached.

Returns

IControlState

Inherited from

Control.getState

getWidgetStatus()

getWidgetStatus(): IWidgetStatus

Defined in: js-api/src/widgets/base.ts:432

Returns the widget's runtime structure for automated testing and introspection; state is read off the DOM (kind, label, enabled, visible, focused …), then merged with what providers contribute.

Returns

IWidgetStatus

Overrides

Control.getWidgetStatus

link()

link(name, source, twoWay): void

Defined in: js-api/src/u2core/component.ts:453

Keeps this component's name step and source equal, echo-suppressed by value; the reverse direction only where twoWay. A component that took source as its own signal needs no link and gets none; a read-only step cannot follow anything and gets none either.

Parameters

Parameter	Type
`name`	`string`
`source`	`Signal`<`unknown`>
`twoWay`	`boolean`

Returns

void

Inherited from

Control.link

on()

on(eventId, handler): () => void

Defined in: js-api/src/u2core/component.ts:623

Subscribes handler to onEvent(eventId); it gets the payload and this component. Owned by the ambient scope when there is one (the subscriber's), else by this component; runs as Scope.bind runs a handler. Answers the unsubscribe.

Parameters

Parameter	Type
`eventId`	`string`
`handler`	(`arg`, `source`) => `void`

Returns

() => void

Inherited from

Control.on

onEvent()

onEvent(eventId?): Observable<any>

Defined in: js-api/src/widgets/base.ts:423

Observes events with the specified eventId: what fireEvent raises and, for an id, the DOM events of that name on the root — as on every u2 Control.

Parameters

Parameter	Type	Default value
`eventId`	`string` \| `null`	`null`

Returns

Observable<any>

Overrides

Control.onEvent

onFrameAttached()

onFrameAttached(dataFrame): void

Defined in: js-api/src/widgets/base.ts:304

Returns

void

own()

own(dispose): this

Defined in: js-api/src/u2core/component.ts:267

Registers a cleanup that runs when this component is disposed.

Parameters

this

Inherited from

Control.own

propertyChanges()

protected propertyChanges(): ObservableLike<PropertyChange>

Defined in: js-api/src/widgets/base.ts:375

Returns

ObservableLike<PropertyChange>

Overrides

Control.propertyChanges

registerFunction()

protected registerFunction(f): void

Defined in: js-api/src/u2core/component.ts:616

Returns

void

Inherited from

Control.registerFunction

removeStatusProvider()

removeStatusProvider(name): void

Defined in: js-api/src/widgets/base.ts:477

Removes the status contribution registered under name; an absent name is a no-op.

Parameters

Parameter	Type	Description
`name`	`string`	The name passed to addStatusProvider.

Returns

void

Example

widget.removeStatusProvider('selection');
see samples/grid/custom-renderer-status

revealItem()

revealItem(keyOrLabel): Promise<HTMLElement | null>

Defined in: js-api/src/u2core/component.ts:746

Brings the item into view and resolves to its element, or null when none matches: the exact key (data-u2-item) first, then the label, trimmed and case-insensitive. Several label matches reject, naming the candidates. This base searches the rendered [data-u2-item] elements under the root and in the popups it owns; a virtual or collapsible control overrides it to scroll or expand first.

Parameters

Parameter	Type
`keyOrLabel`	`string`

Returns

Promise<HTMLElement | null>

Inherited from

Control.revealItem

runInScope()

runInScope<T>(fn): T

Type Parameters

Type Parameter
`T`

Parameters

Parameter	Type
`fn`	() => `T`

Returns

T

Deprecated

Use the owner verb build(fn) (OwnerVerbs.build): this.build(fn), dialog.build(fn).

find()

static find(root): Widget<any> | null

Defined in: js-api/src/widgets/base.ts:243

Finds existing widget from its visual root.

Parameters

Parameter	Type
`root`	`Element`

Returns

forElement()

static forElement(el): Control | undefined

Defined in: js-api/src/u2core/component.ts:904

Best-effort: the last control constructed on (or assigned) a root wins it. The root carries the control under Symbol.for('u2.control'), so every engine copy on the page answers alike.

Parameters

Parameter	Type
`el`	`Element` \| `null`

Returns

Control | undefined

Inherited from

Control.is

jsonValue()

static jsonValue(x, depth?): JsonValue | undefined

Defined in: js-api/src/u2core/component.ts:826

The JSON-safe projection behind IControlState.value: a Date → its ISO string, an object with a string name (an entity, a column) → the name, arrays and sets element-wise, plain objects key-wise (depth 4), a signal → its current value; functions and elements → undefined; anything else → String(x).

Parameters

void

sameValue()

static sameValue(a, b): boolean

boolean

Inherited from

Control.sameValue

text()

protected static text(el): string

Defined in: js-api/src/u2core/component.ts:789
