QTXlib is a small library for primitive graphic output directly using Xlib from inside Qt-based applications for improved performance compared to Qt (but less portability). QTXlib is being developed by me (since 2002) and distributed under the GNU GPL.
Brief overview of QTXlib
Historically, QTXlib was developed because Qt's graphic primitives turned out to be quite inefficient when it comes to mass drawings of filled rectangles and the line. And as the runtime of some nice simulations depends heavily on the speed of graphical output, I decided that an Xlib-based implementation had to be written which must be usable from within Qt's QWidgets.
The primary design goals were, in this order:
