University of Washington site. The ad hoc manner in which direct manipulation interfaces have been designed and implemented restricts the types of interactive controls. This dissertation presents a new approach for a systematic method to implement flexible, combinable interactive controls. Both are tested and run on most platforms. Describes Garnet motives, rationale.
Constraints provide a useful mechanism to maintain relations in user interface toolkits.
Garnet is a widely used user interface toolkit with high functionality, based on one way, required constraints. Frequently Asked Questions about Garnet user interface development environment for Common Lisp and X11 or Macintosh developed by User Interface Software Group, Human-Computer Interaction Institute, Carnegie Mellon University. This area is of the set of less known software technologies, but is evolving rapidly and has a growing, significant commercial interest. Software component provider of constraint programming based solving engines for resource optimization, business rule engines, etc. In the last 20 years, many algorithms and heuristics were developed to find solutions in constraint networks.
