E-Level

Overview

Progress

Iteration 6 is the final iteration of E-Level for Object Oriented Software Engineering. In that respect, we spent this iteration improving the GUI and usability, fixing bugs, and optimizing code in preparation for the beta release. More refactoring was performed and serialization was improved to handle more advanced drawing features. Graphing features were added to graphically view test statistics. The application was successfully bundled into executable jar files for deployment.

Over 12,000 lines of code have now been written, comprising 370 commits to the repository.

Executables

Executable jar files are now available for all platforms supporting 32-bit Java 1.6:

The application has been tested on Windows XP, Vista, and 7 and OS X 10.5, 10.6, Debian, and Kubuntu, and Fedora 9 Linux.

Future Plans

As a team, we believe that E-Level has significant useful functionality, and believe the project should be carried on. A primary component of that is porting the code from the unsupported Qt Jambi bindings for Java to the newest release of Qt, 4.6, rewriting the application in C++. This will allow us to accomplish more of our original goals, including using the new Phonon libraries to handle video and audio multimedia, and allowing for the localization of our program in other languages.

We would also like to accomplish our goal of interchangeable drawing toolbars, each with different functionality, whether chemistry, math, or foreign languages, as well as stamp out any remaining bugs, of course.
