HyperGUI

HyperGUI is a library of C++ classes and some other parts which can draw and run a GUI for your application. It uses libSDL as its backend for graphical output.
This library can be used in both dynamic multimedia (game), and standard (static) applications. The HyperGUI manages it by avoiding screen refreshes as much as possible. In a game or other dynamic multimedia program, the screen (or part of it) is redrawn and refreshed tens of times a second, so there is no need for GUI to ask more refreshes in response of input events; and in a static application each event may change a tiny part of the screen, and only that part needs redrawing. HyperGUI has the flexibility to work in both states.
