Struct GlContext 

pub struct GlContext { /* private fields */ }

A CGL context.

Implementations

impl GlContext

pub fn context(&self) -> Option<ComPtr<IFrnGlContext>>

The native context; None once the context is disposed (lost).

pub fn throw_if_lost(&self)

Panics

Panics when the context is lost (the PlatformGraphicsContextLostException of the original).

Trait Implementations

impl IGlContext for GlContext

fn make_current(&self) -> Rc<dyn IDisposable>

Panics

Panics when the context is lost and when the native context cannot be made current.

fn is_shared_with(&self, context: &dyn IGlContext) -> bool

Panics

Panics when context is not a context of this backend (the failing cast of the original).

fn create_shared_context( &self, _preferred_versions: Option<&[GlVersion]>, ) -> Option<Rc<dyn IGlContext>>

Creates a context that shares its objects with this one (with the context this one shares with, when it does). The preferred versions are not used, as in the original. A failure is logged and gives None (the original throws), as for the contexts of GLX and EGL.

fn version(&self) -> GlVersion

The version of the API the context implements.

fn gl_interface(&self) -> Rc<GlInterface>

The entry points of the context.

fn sample_count(&self) -> i32

The number of samples of the default framebuffer.

fn stencil_size(&self) -> i32

The number of stencil bits of the default framebuffer.

fn can_create_shared_context(&self) -> bool

Whether create_shared_context is supported.

impl IOptionalFeatureProvider for GlContext

fn try_get_feature(&self, feature_type: TypeId) -> Option<Rc<dyn Any>>

Queries for an optional feature.

impl IPlatformGraphicsContext for GlContext

fn is_lost(&self) -> bool

Whether the context is lost and cannot be used anymore.

fn ensure_current(&self) -> Rc<dyn IDisposable>

Makes the context current. Disposing the result restores the previously current context.

fn dispose(&self)

Releases the context.

fn as_any(&self) -> &dyn Any

Lets the backend recover the concrete context type.
