PUBLIC SUB Form_MouseWheel()
SELECT CASE Mouse.delta
CASE 1
PRINT "mouse wheel up"
CASE -1
PRINT "mouse wheel down"
END SELECT
END
I don't know about sdl. You could use aumix. i.e
SHELL "aumix -v +5" WAIT
increase the current main volume by 5 points.
SHELL "aumix -v -25" WAIT
decrease the current main volume by 25 points.
SHELL "aumix -v 100" WAIT
set the volume to the maximum. Et cetera...
See aumix --help and do some experiments.
P.S. I'm not sure thet aumix is on all GNU/linux systems around ;-)
Ciao.
