NavigationToggleViewModel | API Reference | ArcGIS Maps SDK for JavaScript 4.30

Provides the logic for the NavigationToggle widget, which provides two simple buttons for toggling the navigation mode of a SceneView. Note that this is not designed for 2D mouse interaction in a MapView, nor for touch navigation.

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.
