And FLTK is great too.
I did locate this module very fast, after my post wasn't answered quickly, so I thought my question seems not to be easily answered and I started digging. I have checked and patched this module to make the shade color available but, this is not as easy as it looks it is. The gc argument is a character which gets used as an index into ramp arrays. Higher level functions provide a string of characters to apply shading. I tried with several characters (as they are used in fl_plastic.cxx) but the result was not as expected. I did not dig deeper to understand what is going on there, so the use of fl_color_average, which I discovered in Enumeration.h, does it for me. Probably it would be nice to have an interface to inquire the solid color used, based on the scheme selected. _______________________________________________ fltk mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk
