SliceViewModel

Property Overview

Property Details

analysis SliceAnalysisautocastreadonly

Since: ArcGIS Maps SDK for JavaScript 4.23

The slice analysis object being created or modified by the view model.

This property can be set during view model construction, to provide an existing analysis to the view model for modification. Properties on the analysis can also be updated once it's assigned to the view model.

If no analysis is provided during view model construction, the view model automatically creates its own analysis and adds it to the view. In this case, the analysis will also be automatically removed from the view when the view model is destroyed.

Example

// Construct a slice analysis object outside of the view model
const analysis = new SliceAnalysis({
  shape: {
    type: "plane", // autocasts as new SlicePlane()
    position: {
      type: "point",
      x: -0.1,
      y: 51.5
    },
    width: 50,
    height: 50,
    tilt: 45
  },
  tiltEnabled: true
});

// Ensure that the analysis is added to the view
view.analyses.add(analysis);

// Frame the analysis in the view
view.goTo(analysis.extent);

// Pass the analysis object as a constructor parameter to modify it using the view model
const viewModel = new SliceViewModel({
  analysis: analysis,
  view: view
});

declaredClass Stringreadonly inherited

The name of the class. The declared class name is formatted as esri.folder.className.

excludedLayers Collection<(Layer|BuildingComponentSublayer)>

Add layers to this collection to exclude them from the slice. Layers that are draped on the ground surface are not affected by this property

excludeGroundSurface Boolean

Indicates whether the Ground and layers that are draped on the ground surface are excluded from the slice.

Default Value:false

shape SlicePlaneautocast

Since: ArcGIS Maps SDK for JavaScript 4.16

The shape used to slice elements in a 3D scene. Currently the only supported shape is a plane.

Example

// Clone the shape to modify its properties
const shape = viewModel.shape.clone();

// Set new values for heading and tilt
shape.heading = 180;
shape.tilt = 45;

// Set the new properties on the viewModel's shape
viewModel.shape = shape;

state Stringreadonly

The view model's state.

Value	Description
disabled	not ready yet
ready	ready for slicing
slicing	currently slicing
sliced	finished slicing

Possible Values:"disabled"|"ready"|"slicing"|"sliced"

Default Value:disabled

tiltEnabled Boolean

Since: ArcGIS Maps SDK for JavaScript 4.16

Enable tilting the slice shape. If set to true, the slice shape will orient itself as best as possible to the surface under the cursor when first placing the shape. If set to false, the slice shape is restricted to be either horizontal or vertical.

Default Value:false

view SceneView

The view from which the widget will operate.

Method Overview

Method Details

addHandles(handleOrHandles, groupKey)inherited

Since: ArcGIS Maps SDK for JavaScript 4.25

Adds one or more handles which are to be tied to the lifecycle of the object. The handles will be removed when the object is destroyed.

// Manually manage handles
const handle = reactiveUtils.when(
  () => !view.updating,
  () => {
    wkidSelect.disabled = false;
  },
  { once: true }
);

this.addHandles(handle);

// Destroy the object
this.destroy();

Parameters

handleOrHandles WatchHandle|WatchHandle[] Handles marked for removal once the object is destroyed.

groupKey * optional Key identifying the group to which the handles should be added. All the handles in the group can later be removed with Accessor.removeHandles(). If no key is provided the handles are added to a default group.

clear()

Since: ArcGIS Maps SDK for JavaScript 4.16

Clears the shape of the slice, effectively removing it from the view. Other properties like excludedLayers and excludeGroundSurface are not modified.

hasHandles(groupKey){Boolean}inherited

Since: ArcGIS Maps SDK for JavaScript 4.25

Returns true if a named group of handles exist.

Parameter

groupKey * optional A group key.

Returns

Type	Description
Boolean	Returns true if a named group of handles exist.

Example

// Remove a named group of handles if they exist.
if (obj.hasHandles("watch-view-updates")) {
  obj.removeHandles("watch-view-updates");
}

removeHandles(groupKey)inherited

Since: ArcGIS Maps SDK for JavaScript 4.25

Removes a group of handles owned by the object.

Parameter

groupKey * optional A group key or an array or collection of group keys to remove.

Example

obj.removeHandles(); // removes handles from default group

obj.removeHandles("handle-group");
obj.removeHandles("other-handle-group");

start()

Since: ArcGIS Maps SDK for JavaScript 4.16

Starts the interactive creation of a new slice, clearing the previous shape.
