I am working on getting McCLIM working on Lispworks7 on Windows 10. All is going well and I will have a few patches to contribute soon.
I do have 32 bit Lispworks Professional here, with CLIM2, that I have been using for quite awhile now so I have my own code to use for testing the port. One fairly simple plotting program put up a frame with no complaints but appeared to show nothing on the screen. I traced the issue to a disagreement between clim2 and McCLIM implementations in transformation composition which caused my expected image to display way out of the clipping region. This bit of code shows the problem...
(defun txf() (let ((scale-x 2.35) (scale-y 24.7) (origin-x 38.0) (origin-y 263.0)) (let* ((st (clim:make-scaling-transformation scale-x (- scale-y))) ;;#<CLIM-INTERNALS::STANDARD-HAIRY-TRANSFORMATION ;; 2.35 0 0 -24.7 0.0 0.0> (tt (clim:make-translation-transformation origin-x origin-y)) ;;#<CLIM-INTERNALS::STANDARD-TRANSLATION :DX 38.0 :DY 263.0> (ct1 (clim:compose-transformations tt st)) ; correct in clim2 & Mcclim ;;#<CLIM-INTERNALS::STANDARD-HAIRY-TRANSFORMATION 2.35 0.0 0.0 -24.7 38.0 263.0> <<<<< ;; McCLIM gets this wrong (assuming clim2 is correct). (ct2 (clim:compose-transformation-with-translation (clim:make-scaling-transformation scale-x (- scale-y)) origin-x origin-y)) ;;#<CLIM-INTERNALS::STANDARD-HAIRY-TRANSFORMATION ;; 2.35 0.0 0.0 -24.7 89.299996 -6496.1> <<<<< ) (values st tt ct1 ct2))))
Reading the clim2 spec, I think clim2 implements it correctly.
