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

display -- a gdk:display object

The newly created gdk:gl-context object.

Creates a new OpenGL context for the display. The context is disconnected from any particular surface and cannot be used to draw to any surface. It can only be used to draw to non-surface framebuffers like textures.

If the creation of the OpenGL context failed, an error will be set. Before using the returned OpenGL context, you will need to call the gdk:gl-context-make-current or gdk:gl-context-realize functions.
