autoDestroyDisabled

Property

Type: boolean

If true, the component will not be destroyed automatically when it is disconnected from the document. This is useful when you want to move the component to a different place on the page, or temporarily hide it. If this is set, make sure to call the destroy() method when you are done to prevent memory leaks.

Attribute: auto-destroy-disabled
Default value: false

icon

Property

Type: string | undefined

Icon which represents the component. Typically used when the component is controlled by another component (e.g. by the Expand component).

Calcite Icons

Attribute: icon
Default value: "magnifying-glass-plus"

label

Property

Type: string | undefined

The component's default label.

Attribute: label

layout

reflected Property

Type: Layout

Determines the layout/orientation of the Zoom component.

Attribute: layout
Default value: "vertical"

messageOverrides

Property

Type: Record<string, unknown> | undefined

Replace localized message strings with your own strings.

Note: Individual message keys may change between releases.

referenceElement

Property

Type: ArcgisReferenceElement | string | undefined

By assigning the id attribute of the Map or Scene component to this property, you can position a child component anywhere in the DOM while still maintaining a connection to the Map or Scene.

Associate components with a Map or Scene component

Attribute: reference-element

state

readonly Property

Type: State

The current state of the component.

view

Property

Type: MapView | SceneView | undefined

The view associated with the component.

Note: The recommended approach is to fully migrate applications to use map and scene components and avoid using MapView and SceneView directly. However, if you are migrating a large application from widgets to components, you might prefer a more gradual transition. To support this use case, the SDK includes this view property which connects a component to a MapView or SceneView. Ultimately, once migration is complete, the arcgis-zoom component will be associated with a map or scene component rather than using the view property.

visualScale

Property

Type: Button["scale"]

Since: ArcGIS Maps SDK for JavaScript 5.0

Specifies the size of the component.

Attribute: visual-scale
Default value: "m"
