This document has been written to help you use the new Eclipse 3.0 feature called 'Eclipse Forms'. The content will eventually move to Eclipse help. In the mean time, you can start experimenting using examples shown below and code in Eclipse 3.0 integration builds.
Eclipse Forms is a plug-in that exposes a set of customs widgets and other supporting classes that were before used as internal to PDE and Update components. They provide for creating polished, 'Web-like' UIs by modestly extending SWT and/or manipulating style bits, colors, fonts and other properties in order to get the desired behavior. This technology was used throughout PDE multi-page editors and will now be available as public API in Eclipse 3.0.
