Abstract
The authors address the question of event-handling for declarative
visual languages. In the approach presented, system-level, interactive,
and user-defined events are fully-supported, while still maintaining the
property of referential transparency. An approach to time termed
temporal assignment provides a unifying mechanism for events to be
defined as ordinary sequences of values, and conversely for ordinary
sequences of values to be defined as events. This allows event-handling
without additional concepts, and in particular provides a natural means
for the user to define higher-level events of any kind
