Graphical user interface (GUI) in Scilab allows you to operate the software programmes with a point-and-click interface, eliminating the need for others to learn a language or type commands in order to run the programme.
Scilab offers multiple options for developing a GUI. Among all the GUI approaches, the GUI Builder toolbox is the most extensively used. With this toolbox, creating a GUI is very simple. This toolbox is developed by Tan Chin Luh and David Violeu. This is the fastest and easiest way to create the GUI in Scilab.
This series shows how to make a Graphic user interface (GUI) from scratch and with the GUI Builder toolbox.
IIT Bombay is leading the effort to popularise Scilab in India and Graphic user interface (GUI) is one of the best features of Scilab. This effort is part of the Free and Open source Software for Science and Engineering Education (FOSSEE) project, supported by the National Mission on Education through ICT of the Ministry of Education.
IIT Bombay is using Spoken Tutorials (http://spoken-tutorial.org) to create learning material for various FOSS. This is the main page for the organisation of the scripts required for Scilab spoken tutorials. We invite the Scilab user community to participate in this activity.
The content for this series was contributed by FOSSEE interns 2021 Amandeepsingh Siddhu, Iswariya Sasikumar and Utkarsh Anand. Overall coordination for the series was done by Rashmi Patankar from FOSSEE project, IIT Bombay. Ms. Nancy Varkey and Dr. Rani from Spoken Tutorial project, IIT Bombay, were the reviewers from the ST end.
Learners: All Science and Engineering Students.
