NavigationToggle

require(["esri/widgets/NavigationToggle"], function(NavigationToggle) { /* code goes here */ });

Class: esri/widgets/NavigationToggle

Inheritance: NavigationToggle Widget Accessor

Since: ArcGIS API for JavaScript 4.0

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.

For information about gaining full control of widget styles, see the Styling topic.

Example:

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

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

container String|HTMLElement inherited

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 cases 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"
});
