gdk:surface-create-gl-context (surface)

surface -- a gdk:surface object

The newly created gdk:gl-context object.

Creates a new OpenGL context matching the framebuffer format to the visual of the surface. The context is disconnected from any particular surface.

Before using the returned OpenGL context, you will need to call the gdk:gl-context-make-current or gdk:gl-context-realize function.
