Struct glutin::HeadlessContext
[−]
[src]
pub struct HeadlessContext { /* fields omitted */ }Represents a headless OpenGL context.
Methods
impl HeadlessContext[src]
unsafe fn make_current(&self) -> Result<(), ContextError>[src]
Creates a new OpenGL context Sets the context as the current context.
fn is_current(&self) -> bool[src]
Returns true if this context is the current one in this thread.
fn get_proc_address(&self, addr: &str) -> *const ()[src]
Returns the address of an OpenGL function.
Contrary to wglGetProcAddress, all available OpenGL functions return an address.
fn get_api(&self) -> Api[src]
Returns the API that is currently provided by this window.
See Window::get_api for more infos.
fn set_window_resize_callback(&mut self, _: Option<fn(_: u32, _: u32)>)[src]
