ParaGUI

ParaGUI is a cross-platform high-level application framework and GUI (graphical user interface) library.

It can be compiled on various platforms (Linux, Win32, BeOS, MacOS, ...)

ParaGUI is based on the Simple DirectMedia Layer (SDL).
ParaGUI is targeted on crossplatform multimedia applications and embedded devices operating on framebuffer displays.

Here are some key features of "ParaGUI":

· published under LGPL
· straight forward C++ class-design
· cross-platform
· supports alpha-blending of overlapping widgets
· threadsafe
· highly customizable widgets
· (background gradients, background images, transparency, colors, fonts)
· XML configuration
· many standard widgets already implemented
· (buttons, labels, scrollbars, progressbars, windows ...)
· create your own widgets
· (subclass an existing widget)
· supports various imagetypes through SDL_Image (configurable at compile time)
· using libSigC++ as callback framework
· UNICODE support
