Packages

com.sun.lwuit	Main widget package containing the component/container "composite" similar both in terminology and design to Swing/AWT.
com.sun.lwuit.animations	All components are animatable by potential and additional animations (unrelated to a specific component) can be installed on the fly, transitions between forms are also handled as part of this package.
com.sun.lwuit.events	Observable pattern event listeners in the spirit of AWT 1.1's event dispatching architecture, all events are dispatched on the EDT (Event Dispatch Thread).
com.sun.lwuit.geom	Contains classes related to geometry locations and calculations such as rectangle and size
com.sun.lwuit.html	The HTML package allows rendering XHTML-MP 1.0 documents including WCSS support.
com.sun.lwuit.impl	The implementation package should not be used by developers, it is an internal implementation detail which will break compatibility between major LWUIT releases.
com.sun.lwuit.layouts	Layout managers allow a Container to arrange its components by a set of rules that would be adapted for specific screen/font sizes.
com.sun.lwuit.list	Lists are highly customizable and serve as the basis for ComboBox and other components (such as carousels etc) they employ a similar MVC approach to Swing including the renderer pattern.
com.sun.lwuit.painter	Painter allows us to draw arbitrary elements of graphics from plain/scaled/tiled images to gradients and pretty much any form of graphic drawing we can imagine.
com.sun.lwuit.plaf	Look of the application can be fully customized via this package, it represents a rendering layer that can be plugged in separately in runtime and themed to provide any custom look.
com.sun.lwuit.spinner	Spinners allows picking of simple sequential values similarly to combo boxes but of a much wider value set.
com.sun.lwuit.table	Table component for editing and viewing tabular data and arranging LWUIT components in a tabular form
com.sun.lwuit.tree	Tree component for displaying hierarchy based information and its related classes
com.sun.lwuit.util	Utility features that are either too domain specific or don't "fit" into any other packages.
com.sun.lwuit.xml	The XML package allows parsing XML documents into DOM objects.
