Editor: GLG Toolkit is a state-of-the-art framework for developing highly graphical dynamic Interfaces: not just simple buttons and menus, but fully animated graphical objects that show dynamic data and react to users' interactions. It is not just a drawing tool for creating "pretty pictures" (there are plenty), but a graphical engine that allows developers to define graphical objects and interact with them from a program. It is uniquely targeted towards an application developer, converting a tedious job of coding low-level graphics into an engaging interactive design of high-level behavior.
