Overview

Redkite is a small free software GUI toolkit. It offers graphics widget in a single system window. It is developed in C++ and inspired from other well known GUI toolkits. Currently supports GNU/Linux and Windows.

Goals

• Small and lightweight
• Many instances of the same or different versions of the toolkit must be able to run without problems in the same process address space.
• Can be easily linked statically. Shared libraries that are developed using the toolkit and loaded dynamically must not cause conflicts due to the toolkit.
• Not to add dependencies that breaks the above points. Maximum to relay on dependencies for runtime that are provided by default by the system.
• A simple interface
