Projects / mGSTEP


mGSTEP is a software development framework designed primarily for use in embedded devices. It implements the core elements of NeXT's OpenStep that evolved into Apple's Cocoa Objective-C class libraries. The drawing API is a partial implementation of Display Postscript in parallel with the newer Core Graphics API. The stable GUI (AppKit) is X11 based. A Linux framebuffer based GUI backend is also included.
