We had 'funky' colors too when using FLUID to design a window and running
Microwindows-0.90. We found that the problem was that fltk and nxlib were
using masks and shifts to render the color and send it on to Microwindows,
but we didn't have the RGB masks initialized in our screen info
structure. In the XOpenDisplay() function in nxlib/OpenDis.c, a call to
GrGetScreenInfo(&sinfo) is made. If sinfo.rmask, sinfo.gmask, and
sinfo.bmask aren't correct here, you will get weird looking colors.
We set ours as follows and our color problem cleared up:
sinfo.rmask = 0x00ff0000;
sinfo.gmask = 0x0000ff00;
sinfo.bmask = 0x000000ff;
I hope this helps,
Mark
