There's a new cut, 0.88pre3 at:
ftp://microwindows.censoft.com/pub/microwindows/microwindows-0.88pre3.tar.gz
This version primarily adds dynamic region clipping support, which will
be required for the fltk widget set port that's been started. In addition,
at Alan Cox's request, a define can be unset to run under the smaller
memory usage static cliprect design, for extremely small systems.
The full-blown clip region support is pretty cool, since now Microwindows
performs region Intersect, Xor, Subtract, and Union. This made it quite
easy to add user-specificed clipping regions that can be added/subtracted
from the z-order computed visible region. I've hacked the 3d demo to
display only within a circular region, thus testing CreateRoundRectRegion
as well as blitting into circles. Try it out, it's kinda cool.
In addition, Allistair Riddoch performed an amazing feat in about
50 lines of code - he added client-based window management to his Nano-X
panel program. Now you can exec programs from the Nano-X server,
and move them around!
In addition, Rosimildo's Uniform Input Device and MicroFramebuffer
Architecture common API for RTEMS and other RTOS's is included.
And Victor contributed a TURBOC port, for 16 bit systems, using BGI...
There will likely be a lot of changes soon, as Shane and I get fltk running.
I can't wait. Please send any bugfixes or changes to the list.
