Re: [Pharo-dev] [Pharo-project] Understanding NBOpenGL

Have you tried (gl getString: GL_VERSION) readString or if it does not return an NBExternalAddress (NBExternalAddress value: (gl getString: GL_VERSION)) readstring On Sat, Jun 22, 2013 at 4:46 PM, kilon <thekilon@yahoo.co.uk> wrote:

I am trying to find out what version of Opengl NBOpenGL is using so I do:

gl getString:GL_VERSION.

it works and returns me a pointer. I looked at definition of methods and it is defined to return a pointer.

Question is how I get the string that the pointer points too ?
