Keep the viewpoints of two views, for example, a map view and a scene view, synchronized with each other.
Use case
You might need to synchronize GeoView viewpoints if you had two map views in one application - a main map and an inset. An inset map view could display all the layers at their full extent and contain a hollow rectangular graphic that represents the visible extent of the main map view. As you zoom or pan in the main map view, the extent graphic in the inset map would adjust accordingly.
How to use the sample
Interact with the map view or scene view by zooming or panning. The other map view or scene view will automatically focus on the same viewpoint.
How it works
- Use the
onNavigatingChanged(perform:)modifier on each of the geo views to determine when they are navigating. - When a given geo view is navigating, use the
onViewpointChanged(kind:perform:)modifier to set its new viewpoint on the other geo view’s viewpoint.
