Bindings to the GLFW OpenGL window and event management library, version 3.X.



Direct bindings generated by bind. Names Scheme-ified, with GLFW prefixes removed. Constants surrounded by +s (e.g. +alpha-bits+)

Version 3 of GLFW is not backwards compatible with previous major versions of GLFW.

For information regarding the GLFW API, see the official GLFW documentation.

High-level interface

[procedure] (make-window WIDTH HEIGHT NAME #!key (fullscreen? #f) resizable visible decorated red-bits green-bits blue-bits alpha-bits depth-bits stencil-bits accum-red-bits accum-green-bits accum-blue-bits accum-alpha-bits aux-buffers samples refresh-rate sterio srgb-capable client-api context-version-major context-version-minor context-robustness opengl-forward-compat opengl-debug-context opengl-profile)

Create the window with title string NAME and dimensions WIDTH by HEIGHT. The keys correspond to the available GLFW window hints. resizable, visible, decorated, sterio, srgb-capable, opengl-forward-compat, opengl-debug-context accept boolean arguments, while all other accept either an integer or an appropriate GLFW constant as per the documentation.

[parameter] window

Contains the GLFW window object that is created by make-window.

[syntax] (with-window (WIDTH HEIGHT NAME . KEYS) BODY ...)

Initializes GLFW, creates a window as per make-window, and runs BODY before cleaning up. If opengl-glew has been included in the same file that this macro is used, opengl-glew will also be initialized.


This example must be compiled due to the external function definition.

(import foreign)
(use (prefix glfw3 glfw:) (prefix opengl-glew gl:))

(define-external (keyCallback (c-pointer window)
                              (int key) (int scancode) (int action) (int mods))
   [(and (eq? key glfw:+key-escape+) (eq? action glfw:+press+))
    (glfw:set-window-should-close window 1)]))

(glfw:with-window (640 480 "Example" resizable: #f)
    (glfw:set-key-callback (glfw:window) #$keyCallback)
    (let loop ()
      (glfw:swap-buffers (glfw:window))
      (unless (glfw:window-should-close (glfw:window))
