Modern object-oriented interactive applications have a tendency to be dguult to specie and to des l'gnbecause of dynamicity A formal model based on the integration of communicative nets and colored nets withmpchronous channels is proposed ic cater for this need. Three kinds of nets modeling fore e components of interfaceare given in this paper.The model provides natural descriptions of multi-thread dialogs and the concurrent executingof user interface and aPPlication Procedures and can facilitate rapid protonning and automatic interface codegeneration. 展开更多

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 the runtime structure supporting communication, synchronization, and dialogue execution. 展开更多
