Represents a managed OpenGL context connected to a window or headless surface.

Required Methods

fn is_current(&self) -> bool

Context is current on the calling thread.

fn make_current(&mut self)

Make context current on the calling thread.

fn gl(&self) -> &Rc<dyn Gl>

The context.

fn render_mode(&self) -> RenderMode

Actual render mode used to create the context.

fn resize(&mut self, size: PxSize)

Resize surface.

fn is_software(&self) -> bool

If the context runs on the CPU, not a GPU.

fn swap_buffers(&mut self)

Swap buffers if the context is double-buffered.
