On the way to intelligent query for functions in visual languages
B. Haberland, Jörg Poswig, Carlos Moraga · 2002
The aim of developing a visual programming language is not achieved when the implementation of programs is possible, but still, as in the textual world, a complete software environment is needed. This paper describes an improvement of the function container of VisaVis. The flat 2-dimensional way of accessing functions is replaced by a hierarchical and 3-dimensional one. Cone Trees are extended by a query language into Cone Graphs. The basic concept of user interaction, substitution, was taken from VisaVis. For the optimization of user interaction, a user interface prototype has been developed.>
