Module gl_attr

Available on crate feature dep_sdl3 only.

OpenGL context getters and setters

Example

use sdl3::video::GLProfile;

let sdl_context = sdl3::init().unwrap();
let video_subsystem = sdl_context.video().unwrap();
let gl_attr = video_subsystem.gl_attr();

// Don't use deprecated OpenGL functions
gl_attr.set_context_profile(GLProfile::Core);

// Set the context into debug mode
gl_attr.set_context_flags().debug().set();

// Set the OpenGL context version (OpenGL 3.2)
gl_attr.set_context_version(3, 2);

// Enable anti-aliasing
gl_attr.set_multisample_buffers(1);
gl_attr.set_multisample_samples(4);

let window = video_subsystem.window("sdl3 demo: Video", 800, 600).build().unwrap();

// Yes, we're still using the Core profile
assert_eq!(gl_attr.context_profile(), GLProfile::Core);
// ... and we're still using OpenGL 3.2
assert_eq!(gl_attr.context_version(), (3, 2));
