From Graphical Objects to Terms and Back: an Extended Application Framework for Prolog

We present a framework to build platform-independent, graphical applications in Prolog, implemented upon a C++-based commercial product. This framework is extended with an Introspection/Replication feature which can be seen as object serialization returning Prolog descriptions. Some experiments, especially the prototype of an Interface Builder, indicate that interesting results are obtained in terms of simplicity, generality and portability. 1 Introduction Log e e k ([9]) is the first product of the Development Environment (DE) task of the PROLOPPE project ([8]). The objective of this task is to build a set of graphical tools to help develop Prolog applications. These tools include a Declarative Debugger, a Term Browser and an Interface Builder. Log e e k was developed as a framework to build applications with a Graphical User Interface (GUI) in Prolog, aiming to provide: Prolog as the interface programming language avoiding the need for other scripting languages, which would add no..
