    Easy Beginner's Environment in QT

    Easy Beginner's Environment in QT

    This is a port of the ebe programming environment to QT.

    The ebe programming environment is a nice IDE designed for developing Assembly programs. It also handles C and C++ programs as well since there was not much extra effort. It used to support Fortran and this could return if people want Fortran. This project is an effort to recode ebe using C++ and QT. Originally ebe was coded using Python, Tkinter and Pmw, which worked out pretty well. The QT environment offers substantially better GUI controls. The most obvious difference is that Python ebe has a lot of separate windows, while the QT ebe will use 1 main window and a collection of dockable subwindows. This will make it easier to use.
