autoDestroyDisabled

Property
autoDestroyDisabled: 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
icon: string

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

Attribute

referenceElement

Property

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.

Attribute

state

reflected
Property
state: "disabled" | "ready"

The current state of the component.

Attribute
state
Default value
"disabled"

view

Property

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 Zoom component will be associated with a map or scene component rather than using the view property.
