From their site: UWA (Universal Widget API) is the next generation of the Netvibes wigdet API, the successor of the Netvibes Mini Module API. With this new release, our API becomes a powerful framework for Web widgets development - not only for Netvibes widgets, but also for many other environments, among which are Appleï¿½s Dashboard and the Google Homepage. With the UWA, you only need one API to build widgets for a host of environments.
The following is a list of how-to and tutorial content that matched your search term. ProgrammableWeb's how-to content comes from two sources; full-blown tutorials that we publish ourselves and other highly relevant tutorials that we find elsewhere on the Web. This list represents on combination of both tutorial types and if you go to ProgrammableWeb's API University, you'll not only be able to find more, they are organized based on your role (API providers or developers who consumes APIs). If you know of a tutorial that would be of interest to the ProgrammableWeb community, we'd like to know about it. Be sure to check our guidelines for making contributions to ProgrammableWeb.
