Contents • • • • • • • • Overview [ ] NeXTSTEP (also stylized as NeXTstep, NeXTStep, and NEXTSTEP ) is a combination of several parts: • a operating system based on the, plus source code from • and a proprietary windowing engine • the language and runtime • an (OO) application layer, including several 'kits' • development tools for the OO layers NeXTSTEP is notable for having been a preeminent implementation of the latter three items. The toolkits offer considerable power, and are the canonical development system for all of the software on the machine. It introduced the idea of the (carried through and into today's ) and the. NeXTSTEP also originated or innovated a large number of other concepts which became common in other operating systems: 3D 'chiseled' widgets, large full-color, system-wide drag and drop of a wide range of objects beyond file icons, system-wide piped, real-time scrolling and window dragging, properties dialog boxes called 'inspectors', and window modification notices (such as the saved status of a file).
