The Dekho Map Client is implemented with Adobe Flex and the ESRI Flex API. The clients ĎAbout Formí can be used to find out what version of the Adobe SDK and ESRI Flex API are being used. This is important when building custom tools because it will need the same version as the client for compatibility.
The Map Client can run in one of two modes: simple, or application. In simple mode, map navigation is controlled by a zoom slider, and the map services buttons. Simple mode is designed for when the Map Client is tightly integrated with another application that requires some straightforward mapping/GIS functionality. In application mode, a toolbar provides access to the full functionality of Dekho.
