The Ecere SDK is a cross-platform toolkit for building software applications. It currently runs on Windows, Linux, Mac OS X (through X11), FreeBSD, and the Android OS. It should run on other Unix platforms with minor testing/tweaking. With the Ecere SDK, you can develop applications once and deploy them on all supported platforms alongside a lightweight runtime environment. It introduces eC, an object oriented language derived from and fully compatible with C, compromising neither runtime performance nor ease of use. A built-in 3D engine supporting both Direct3D and OpenGL is fully integrated.
Enhanced Dispositioned Keyboard consists of a C++ library (libedk), a keyboard layout editor (edk), and a simple test application. It supplies support for multiple keyboard layouts in one application without the need for additional keyboard switches, and makes it simple to create applications that use English (Latin), Russian (Cyrillic), Chinese, and every other Unicode character set.
Essential Budget a personal finanance manager that fully supports creating and tracking a budget against actual expenses. With a high-quality, cross-platform, professional user interface, it simply performs all of the basic features expected of a personal finance manager, and aims to replace tools like Quicken(tm) for home finance management in the future.
FLTK (pronounced "fulltick") is a cross-platform C++ GUI toolkit for UNIX/Linux (X11), Microsoft Windows, and Mac OS X. It provides modern GUI functionality without the bloat, and supports 3D graphics via OpenGL and its built-in GLUT emulation. FLTK is designed to be small and modular enough to be statically linked, and also works fine as a shared library. It also includes an excellent UI builder called FLUID that can be used to create applications in minutes.
