NavigationToggle | API Reference | ArcGIS Maps SDK for JavaScript

Provides two simple buttons for toggling the navigation mode of a SceneView. Note that this widget is designed only for 3D mouse interaction in a SceneView. It has no effect on touch navigation and it should not be used with 2D mouse interaction in a MapView.

navigation-toggle

The default navigation mode of the SceneView is always pan. The various mouse interactions of this mode are outlined here. The alternate navigation mode to toggle to is rotate. This allows the user to rotate the view with a mouse drag and pan the view with a right-click and drag gesture.

You can use the view's DefaultUI to add widgets to the view's user interface via the ui property on the view. See the example below.

NavigationToggleViewModel - Deprecated since 4.33. Use the Navigation Toggle component instead.

Example

// creates a new instance of the NavigationToggle widget
let navigationToggle = new NavigationToggle({
  view: view
});

// and adds it to the top right of the view
view.ui.add(navigationToggle, "top-right");

Property Details

container Inherited Property container HTMLElement |null |undefinedautocast Inherited from Widget Autocasts from String

The ID or node representing the DOM element containing the widget. This property can only be set once. The following examples are all valid use case when working with widgets.

Examples

// Create the HTML div element programmatically at runtime and set to the widget's container
const basemapGallery = new BasemapGallery({
  view: view,
  container: document.createElement("div")
});

// Add the widget to the top-right corner of the view
view.ui.add(basemapGallery, {
  position: "top-right"
});

// Specify an already-defined HTML div element in the widget's container

const basemapGallery = new BasemapGallery({
  view: view,
  container: basemapGalleryDiv
});

// Add the widget to the top-right corner of the view
view.ui.add(basemapGallery, {
  position: "top-right"
});

// HTML markup
<body>
  <div id="viewDiv"></div>
  <div id="basemapGalleryDiv"></div>
</body>

// Specify the widget while adding to the view's UI
const basemapGallery = new BasemapGallery({
  view: view
});

// Add the widget to the top-right corner of the view
view.ui.add(basemapGallery, {
  position: "top-right"
});

declaredClass Inherited Property declaredClass Stringreadonly Inherited from Accessor Since: ArcGIS Maps SDK for JavaScript 4.7 Accessor since 4.0, declaredClass added at 4.7.

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

destroyed Inherited Property destroyed Boolean Inherited from Widget

When true, this property indicates whether the widget has been destroyed.

id Inherited Property id String Inherited from Widget

The unique ID assigned to the widget when the widget is created. If not set by the developer, it will default to the container ID, or if that is not present then it will be automatically generated.

label Property label String Since: ArcGIS Maps SDK for JavaScript 4.7 NavigationToggle since 4.0, label added at 4.7.

The widget's default label.

layout Property layout String

Sets the layout of the widget to either horizontal or vertical. See the table below for a list of possible values.

Possible Value	Example
vertical
horizontal

Possible Values:"vertical" |"horizontal"

Default Value:"vertical"

Example

// creates a new instance of the NavigationToggle widget
let navigationToggle = new NavigationToggle({
  view: view,
  layout: "horizontal"  // makes the layout horizontal
});

view Property view SceneView |null |undefined

A reference to the SceneView. Set this to link the widget to a specific view.

viewModel Property viewModel NavigationToggleViewModelautocast

The view model for this widget. This is a class that contains all the logic (properties and methods) that controls this widget's behavior. See the NavigationToggleViewModel class to access all properties and methods on the widget.

visible Inherited Property visible Boolean Inherited from Widget

Indicates whether the widget is visible.

If false, the widget will no longer be rendered in the web document. This may affect the layout of other elements or widgets in the document. For example, if this widget is the first of three widgets associated to the upper right hand corner of the view UI, then the other widgets will reposition when this widget is made invisible. For more information, refer to the css display value of "none".

Default Value:true

Example

// Hides the widget in the view
widget.visible = false;

Method Details

addHandles Inherited Method addHandles(handleOrHandles, groupKey) Inherited from Accessor Since: ArcGIS Maps SDK for JavaScript 4.25 Accessor since 4.0, addHandles added at 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

// Destroy the object
this.destroy();

Parameters

handleOrHandles WatchHandle|WatchHandle []

Handles marked for removal once the object is destroyed.

let view = new MapView();
view.when(function(){
  // This function will execute once the promise is resolved
}, function(error){
  // This function will execute if the promise is rejected due to an error
});
