Developing software using X Windows

The X Window System is the current de-facto standard for window management on workstations with high resolution bitmapped displays. An application programmer using these workstations will encounter X both as a user working within the X environment and also as a programmer using X to develop graphical user interfaces (GUIs) for their applications. The basic concepts of X are described, and a brief description of the toolkits and tools available to an application programmer wanting to use X is given. Some current problems encountered using X are discussed and some pointers to future directions for GUI development environments are given
