This article shows how to get the geolocation of the user's mouse click.
The code example sets up an Event Listener on the click event of the Map Display. The x and y pixel values are extracted from evt.displayX and evt.displayY and converted to geo.Coordinates. Remember to add in your own AppId and Token to get the example to work.
