Lgi

LGI is a GUI framework for abstracting out all the operating system dependencies that you can produce portable code. It handles all the graphical interface functions, threading and semaphores, network connectivity and lots of other bits and pieces to help build small, fast and reliable applications.The strengths of LGI is that it's a small enough library that one person can understand it all. Also it's not too much of a burden on an application, both in increased download time and memory footprint. LGI at the moment compresses to about 300kb, which while not insignificant is quite a bit smaller than the other options.Ultimately however size is a secondary consideration to the core feature of LGI and that is portability. Currently 3 serious ports exist: Win32, Mac and Linux. There is also a legacy BeOS port which is unsupported.
