agar

Cross-platform GUI toolkit

Agar is a cross-platform GUI system. It provides a base framework and a toolkit of widgets from which portable, high-performance graphical applications can be built. The toolkit is extensible through class registration. A style engine allows precise control over the appearance of elements. Agar applications work under X Windows, MS Windows, MacOS, SDL (1.2 and 2.0) and others. It can attach to an existing graphical context and work as self contained window manager. Agar is fully thread-safe when built with threads support.
