Introduction
The Lightweight User Interface Toolkit(LWUIT) is a widget library that you can bundle with your application. Lightweight refers to the library’s small footprint and moderate device requirements. With LWUIT, resource-constrained devices can have a rich look and feel. Inspired by Swing, the toolkit implements a peer-less graphics and UI model in a compact package. LWUIT is an open source project. To join the community, visithttp://lwuit.java.net.
