Manipulating light using class

Ive created a class that holds all the light parameters neede : Position,Direction,Specular color,Diffusion color,its index(used GL_LIGHT1 as the first and a static counter reference for the next). The class is suppose to turn on/off (glEnable/Disable..) the light , set new values etc. The problem : it isnt working !!!
Must I use the usual function inside the render/Callback functions ?

Erm, not working in what way? Do you get any lighting at all? Or you can’t change the values? And are you sure you do glEnable(GL_LIGHTNING) to enable lights at all?


Not working in manner that I can`t make things happen !!!
I assume the problem is getting The glEnable/glDisable enumrator working .

Why are you using GL_LIGHT1 as the first?
Implementations could limit the number of lights, and you are supposed to use the first available set.
Also, check out specs about default light parameters. LIGHT0 has different defaults from the others.
