Object-oriented programming with the X Window system toolkits

From the Publisher: This book describes the X Window System, a recent and important software development. Though the norm for PC's is still proprietary window systems, X provides an ``open'' window system that can support a variety of window managers, toolkits and interface builders. This is particularly true for the UNIX-based workstation community, although X is not tied to any particular hardware or software system. The author describes various sophisticated techniques with which the reader can implement graphical user interfaces (GUI's), without imposing user-interface styles, thus making available a generic window support system.
