Software Technology for Adaptable, Reliable Systems (STARS). Ada/Xt Toolkit Version 2.2 SunOS Implementation

Abstract

This software package provides an Ada programmatic interface to a set of reusable user interface abstractions known as widgets. The software provides the full functionality of the M.I.T. X Consortium Version 11 Release 3 X Window System. The software consists of three components: an Ada binding to the Xlib layer, an Ada implementation of the Xt Intrinsics layer, and an Ada widget library. The Ada binding to the Xlib layer is an upgrade of the STARS Foundation Ada Xlib binding, and provides a protocol interface including a set of graphics drawing primitives. The Xt Intrinsics layer provides a policy-free mechanism for creating and managing user interface objects. User interface objects are contained in the widget library which consists of a small set of commonly used user interface abstractions such as scrollbars and command buttons. (KR)
