Your error line 111 is in the last line, right? You're passing in
pointers to floats instead of floats themselves like the
-colorWithCalibratedRed:green:blue:alpha: requires.
I
'm not sure what else you're doing outside of this block of code, but I
think what you want is:
float ws1R;
float ws1G;
float ws1B;
timerValue = [[dictws1 objectForKey: @"R"]retain];
ws1R = [timerValue intValue];
[timerValue release];
timerValue = [[dictws1 objectForKey: @"G"]retain];
ws1G = [timerValue intValue];
[timerValue release];
timerValue = [[dictws1 objectForKey: @"B"]retain];
ws1B = [timerValue intValue];
[timerValue release];
NSColor *col = [NSColor colorWithCalibratedRed:ws1R
green:ws1G blue:ws1B alpha:1.0];

I get this error when I build:
MyProgram.m:111: error: pointer value used where a floating point value
was expected
Is there a way to convery a pointer value to a floating point value.
I may be totally off on my thinking, but I hope you can do what I am
doing above.
Any suggestions on how to fix this?
Thanks,
