Rialto (Rich Internet Application Toolkit) is a cross browser Ajax-based JavaScript widgets library. Because it is technology agnostic it can be encapsulated in JSP, JSF, Python, .Net or PHP graphic components. Development ceased in 2012.[1]
The purpose of Rialto is to ease the access to Rich Internet application development to corporate developers. Ideally a Rialto developer have neither need to write or understand DHTML, Ajax, DOM code or RIA concepts.
Widgets library includes: forms, drag & drop, tree, data list with fix header and resizable columns, pop up, splitter and so on.
Rialto enables Single Page Application development, and is available under open source Apache License.
