Wxshapeframework: an Easy Way for Diagrams Manipulation in C++ Applications
WSEAS TRANSACTIONS on COMPUTERS Michal Bliznak, Tomas Dulik, Vladimir Vasek WXSHAPEFRAMEWORK: AN EASY WAY FOR DIAGRAMS MANIPULATION IN C++ APPLICATIONS MICHAL BLIŽŇÁK1, TOMÁŠ DULÍK2, VLADIMÍR VAŠEK3 Department of Informatics and Artificial Inteligence1, 2, Department of Automation and Control Engineering3 Faculty of Applied Informatics, Tomas Bata University Nad Stráněmi 4511, 760 05, Zlín CZECH REPUBLIC [email protected], [email protected], [email protected] Abstract: wxShapeFramework is new cross-platform software library written in C++ programming language which is suitable for creation of software applications manipulating diagrams, images and other graphical objects. Thanks to the underlying technologies such as wxWidgets toolkit and its XML-based persistent data container add-on called wxXmlSerializer it is an ideal solution for rapid and easy cross-platform visualisation software development. The paper reveals how the wxSF allows user to easily create applications able to interactively handle various scenes consisting of pre-defined or user-defined graphic objects (both vector- and bitmap-based) or GUI controls, store them to XML files, export them to bitmap images, print them etc. Moreover, thanks to applied software licence the library can be used for both open-source and commercial projects on all main target platforms including MS Windows, MacOS and Linux. Keywords: Diagram, vector, bitmap, GUI, wxWidgets, wxXmlSerializer, wxShapeFramework, wxSF, C++ 1 Introduction called shapes (including basic rectangular and elliptic shapes, line and curve shapes, polygonal shapes, static Modern software applications often need the ability to and in-place editable text, bitmap images, etc.). graphically represent various data or logical structures, information flows, processes and similar The wxSF allows to define relationship between abstract information types in the form of diagrams. -

A few proposals were made on the fpc-pascal maillist, abd some discussion followed, but it died out, and there a lot of details of the proposals were only discussed on subthreads. -

Comparative Studies of Six Programming Languages
Comparative Studies of Six Programming Languages Zakaria Alomari Oualid El Halimi Kaushik Sivaprasad Chitrang Pandit Concordia University Concordia University Concordia University Concordia University Montreal, Canada Montreal, Canada Montreal, Canada Montreal, Canada [email protected] [email protected] [email protected] [email protected] Abstract Comparison of programming languages is a common topic of discussion among software engineers. Multiple programming languages are designed, specified, and implemented every year in order to keep up with the changing programming paradigms, hardware evolution, etc. In this paper we present a comparative study between six programming languages: C++, PHP, C#, Java, Python, VB ; These languages are compared under the characteristics of reusability, reliability, portability, availability of compilers and tools, readability, efficiency, familiarity and expressiveness. 1. Introduction: Programming languages are fascinating and interesting field of study. Computer scientists tend to create new programming language. Thousand different languages have been created in the last few years. Some languages enjoy wide popularity and others introduce new features. Each language has its advantages and drawbacks. The present work provides a comparison of various properties, paradigms, and features used by a couple of popular programming languages: C++, PHP, C#, Java, Python, VB. With these variety of languages and their widespread use, software designer and programmers should to be aware -

Web Application for Interoperability Testing of Web Services
Master's Degree in Informatics Engineering Thesis Final Report Web application for interoperability testing of web services Bruno Miguel Filipe Martins [email protected] Supervisor: Prof. Nuno Laranjeiro Date: January 29th, 2016 Master's Degree in Informatics Engineering Thesis Final Report Web application for interoperability testing of web services Author: Bruno Miguel Filipe Martins [email protected] Jury: Prof. Marco Vieira Prof. Carlos Bento Supervisor: Prof. Nuno Laranjeiro Date: January 29th, 2016 WitWS - Web application for interoperability testing of web services Acknowledgments I would like to start by thanking my supervisor, Professor Carlos Nuno Laranjeiro. Without his immeasurable help and guidance this thesis would have been a shadow of itself. To this day I still cannot comprehend how can someone not be completely fed up with me after three meetings a day. His resilience is admirable. To Ivano Elia, for putting up with my endless questions about his previous work. His input throughout the thesis, especially in the testing phase, was invaluable. To Paulo Martins. After a day’s work, after taking care of his own company and after looking for his own family, still having the time to provide me with some tips is nothing short of incredible. To Catarina Lopes, because a long-distance relationship is hard enough without one of the members always complaining about his day. For always having the patience to hear me out even when going through some tough times herself. For understanding that this thesis took a lot more of my time than I expected. And last but definitely not least, to my parents.
