LWUIT is a UI library that is bundled together with applications and helps content developers create compelling and consistent Java ME applications. LWUIT supports visual components and other UI goodies such as theming, transitions, animation and more.
Key features for the current release:
- Bidi support (contributed by Telmap) - allows using LWUIT with Right To Left languages such as Arabic, Hebrew
- Lightweight Virtual keyboard support - allowing for customizable touch screen input
- Pixel based scrolling - allowing scroll to work as expected even when components/containers exceed screen bounds and not just for focusable components
- Table layout and table component - allowing complex tabular UI's including support for features such as spanning rows/columns
- Tree component - supporting nested elements and expanding
- Spinner component for date, time and numeric input within a range
- Reimplementation of the ComboBox widget
- SVG Support integrated into the Theme Creator (formerly LWUIT Designer/Resource Editor)
- Touch device improvements: button menus, improved kinetic scrolling, tactile touch (vibration on touch)
- Resource file specification
- Redesigned the list renderer "rendering" logic so that it paints the backgrounds of the renderers first, and then the selection and foreground.
