This code was written about 1 and a half year ago to test the very
first Qt skeleton. It was in fact the first Qt application and was 
written at a time when Qt only had pushbutton widgets and the drawing
engine was limited to drawing text in a single font and drawing lines
(no kidding, those were the only two drawing operations). In fact the
tetrix project doubled the number of widgets in Qt by introducing
the QLCDNumber widget. The whole application was written in 5 evenings
and 1 weekend and is not very well documented. The tetrix engine is
implemented in the GenericTetrix class and was first made on my
good old 10 MHZ AT where I made a DOS text-mode Tetrix (using about
50 lines) to test it out, it was later moved to a SUN Sparc 10, where it
met Qt. GenericTetrix is totally independent of Qt, feel free to use
it in any way you like. (see the file gtetrix.h for a brief description
of how to use it)

Enjoy!

P.S. Tetrix has later been updated to test out new versions of Qt.

P.P.S The tetrix program uses a special application object called
      QDragApplication. Try to guess what it does.
      Hint: Try pressing the right mouse button somewhere in the
            tetrix window and start dragging....
