Green Dome GNUstepWeb for Mac OS X provides a WebObjects 4.5-like environment for Mac OS X (with some support for WO5 additions). It is composed of modified versions of the standard GNUstepBaseAdditions, GDL2, and GNUstepWeb frameworks, built to run on top of Apple's Cocoa frameworks. The GNUstep frameworks have been built with Xcode as true Mac OS X frameworks. Thus, they may be used as any other framework under Mac OS X. Note that this is a standalone package that does not require or interoperate with a separate GNUstep installation/environment. It is not intended to provide a complete GNUstep environment, such as would be expected of a full GNUstep installation.
PylotLight is a cross-platform, themeable, plugin-supporting system for general computing tasks. It is comparable to QuickSilver, which you may recognize if you use a Mac. Current plugins exist for Web searches, Firefox bookmark launching, filesystem browsing and managing, subversion control, terminal control, and more.
The Lit Window Library is a C++ library which provides "reflections" (extended runtime type information), adds "rules" to the "methods, properties, events" GUI coding paradigm, and contains a collection of frequent UI patterns. The goal of this library is to speed up GUI coding by a factor of 10. It does so by greatly reducing the amount of source code necessary to implement common, day-to-day user interface requirements. This is not just another "better widgets" library. The library introduces two new, different concepts to UI coding: a data abstraction layer (reflections) and rule-based programming.
SLglade is a S-Lang module that provides S-Lang bindings for the libglade library. Used in conjunction with SLgtk, it allows users to design a GUI with Glade (a GTK+ user interface builder), save the interface description in a Glade XML file, and then generate the S-Lang script's graphical interface directly from the XML at runtime.
PageLayout is a layout lanager for Java Swing/AWT that encapsulates, in a single library, the functionality of many other layout managers. It allows you to lay out components in appropriately aligned rows, columns, and grids. The elements of rows, columns, and grids may themselves be rows, columns, and grids of components. As a result, relatively complex layouts can be managed with code that is compact and conceptually quite straightforward to understand and, therefore, maintain.
