Abstract

This paper describes the issues raised by the development of visual tools for the construction of graphical interfaces. It presents Whizz'Ed, an experimental editor for construction of highly interactive or animated applications. In addition to the features of traditional interface builders, Whizz'Ed makes it possible to visually describe by direct manipulation the behaviour of graphical objects and their interrelations. Whizz'Ed encapsulates basic behaviours in elementary bricks that can be connected using a data-flow model. The flow graph can be structured in order to reuse complex behaviours, thus allowing the designer to create new reusable bricks at design time.
