摘要
HAGI is an object-oriented graphics system providing facilities that
structured graphics systems such as GKS usually have. In addition, by adopting
techniques for user interface tools, HAGI is able to support the following features:
?? In addition to graphical objects, the system provides a class of
application objects for modeling of the application in a graphics
application program.
?? Graphics programming is clearly separated into two parts: graphics
specification and graphics manipulation. Graphics manipulation
operations appear to be very simple. They can be issued with respect
to application objects without explicitly referring to specitic graphical
objects.
?? Graphical input is handled by logical interactors, a blend of the
concepts of a logical input device and interaction object. Logical
interactors provide great flexibility and extensibility for constructing
highly interactive graphical user interfaces.
