Lightweight UI Toolkit

The Lightweight UI Toolkit (LWUIT) is a lightweight widget library inspired by Swing but designed for constrained devices such as mobile phones and set-top boxes. Lightweight UI Toolkit supports pluggable theme-ability, a component and container hierarchy, and abstraction of the underlying GUI toolkit. The term lightweight indicates that the widgets in the library draw their state in Java source without native peer rendering.

LWUIT is an open source project whose source is available at https://lwuit.dev.java.net. For more information see the Lightweight UI Toolkit Developer’s Guide. LWUIT binaries can be downloaded from http://java.sun.com/javame/technology/lwuit.

Java ME SDK 3.0 ships with the LWUIT 1.2.1 library. As an open source project, LWUIT has an independent release schedule, consequently, the LWUIT open source project might contain newer libraries and newer documentation. You can add a newer version of the LWUIT library as described in Add a Different LWUIT Library.
