Wazaabi is a UI framework that can be used with eclipse RCP-EMF projects
Wazaabi is a EMF-based declarative UI framework. Wazaabi allows the developer to model the UI using EMF and to render it, live, using different UI platforms like SWT, Swing, or even more. Furthermore it provides a way to describe the style of the UI in separate model, like CSS does it for HTML. Including that and the capability to declare binding to a data model, Wazaabi is one of the most agile UI declaration framework.
