An Approach to User Interface Specification with Attribute Grammars

An approach to supporting user interfaces using an attribute grammmar combined with an event model is described. The main emphasis is how to represent a multi-thread dialogue model in direct manipulation user interfaces. It is shown that control sequence within dialogues, communication with other dialogues,and some computations for applications can be specified with a syntactic and semantic notation. The attribute grammar specification can be implemented using an attribute grammar interpreter embedded in th…
