Graphical User Interface (GUI) development is as important as other aspects and phases of programming, as GUI elements are typically the only means by which the user interacts with the program. Thus, even if the functionality of the application is perfectly executed, if its GUI is difficult to use, this can result in an implementation failure. In such cases, the user will switch to another appl...

In the context of Internet of Things (IoT), the research of this dissertation is concerned with the development of applications for end-user devices, i.e. devices through which the end-user directly interacts with systems. The complexity of such applications is partly due to network intricacies, and partly because GUI (Graphical User Interface) development is generally complicated and time cons...

This tutorial presents Haggis, a graphical user interface framework written in the lazy functional language Haskell. The Haggis framework provides the programmer with a compositional view of graphical user interfaces , where complete GUI applications can be built by repeatedly composing together parts. The individual user interface components are treated as virtual I/O devices that can be inter...

Since a SystemC simulation program is a text-based program that uses files for its inputs and outputs, it is minimally interactive with users. To use the SystemC simulation core for virtual prototyping of embedded systems, a Graphical User Interface (GUI) front end for visualizing behaviors of systems and providing user interaction is required. We propose a method for adding such a GUI front en...

Usability expresses how well a computerised system supports human activity. The humancomputer interaction occurs via the user interface, which is constituted by a Graphical User Interface (GUI) to a great extent. The issue is to integrate GUI design and usability engineering with traditional system development in order to slide on the man-machine scale. The purpose of writing this thesis was to...

Developing query languages and graphical tools for content-based retrieval have brought much attention to researchers recently. In this paper, we describe a new query language as well as a new design to the graphical user interface (GUI) tailored for geographic information systems (GIS). The material presented here is based on the papers written by Egenhofer 1] and by Voisard 2].

Communication between end-users and spatial databases raises important and speciic issues. Unlike classical systems, it requires strong cooperation between two major tools: spatial query language and graphical interface. This paper addresses the problem of building an interactive querying system for spatial databases with an open architecture. We focus on the following issues: (i) design of a d...

A Graphical User Interface (GUI) is the most widely used method whereby information systems interact with users. According to ACM Computing Surveys, on average, more than 45% of software code in a software application is dedicated to the GUI. However, GUI testing is extremely expensive. In unit testing, 10,000 cases can often be automatically tested within a minute whereas, in GUI testing, 10,0...

FastComp is a computational tool for the determination of the forces that a composite bolted joint subjected to multiaxial loads supports until failure occurs. The main intention of the present work was the development of a graphical user interface (GUI) for the referred tool that allows its parameterization and the visualization of its output results. Using VTK The Visualization Toolkit, a com...
