The docs for the Objective-C version say it's a list of integers and
booleans. It looks like you'll need to define the appropriate constants
yourself (Apple's documentation has a list of them), but once you do
that, it should work pretty much as documented (assuming RubyCocoa
properly supports varargs).

By the way, you're not actually writing init.initWithAttributes, are
you?

thanks for info. i've tried many variants to transfer this
constant/int-array to this function with RubyCocoa, but nothing works.
yes, you're right, i've made a typo. i mean:

OSX::NSOpenGLPixelFormat.alloc.initWithAttributes( attribs )

someone on the mailinglist of rubycocoa helped me:

attribs = [OSX::NSOpenGLPFADoubleBuffer,
OSX::NSOpenGLPFAAccelerated,
OSX::NSOpenGLPFAColorSize, BITS_PER_PIXEL,
OSX::NSOpenGLPFADepthSize, DEPTH_SIZE, 0].pack("i*")

nsglFormat = OSX::NSOpenGLPixelFormat.alloc.initWithAttributes(
attribs )

that was the solution.
