Struct FerroNativeGlPlatformGraphics 

pub struct FerroNativeGlPlatformGraphics { /* private fields */ }

The OpenGL platform graphics of the macOS backend: one context shared by every top-level and both threads that render.

Implementations

impl FerroNativeGlPlatformGraphics

pub fn new( display: ComPtr<IFrnGlDisplay>, factory: &ComPtr<IFerroNativeFactory>, ) -> Result<FerroNativeGlPlatformGraphics, OpenGlException>

Creates a context to find out the version of OpenGL the system gives, the entry points and the format of the default framebuffer, then the shared context.

Fails, as the original throws, when the native display cannot create a context or make it current, and when the factory has no memory management helper.

pub fn can_share_contexts(&self) -> bool

Whether contexts may share their objects: always.

pub fn can_create_contexts(&self) -> bool

Whether the graphics create contexts: always.

pub fn gl_display(&self) -> &Rc<GlDisplay>

The display the contexts belong to.

pub fn shared_context(&self) -> &Rc<GlContext>

The context every top-level renders with.

Trait Implementations

impl IPlatformGraphics for FerroNativeGlPlatformGraphics

fn create_context(&self) -> Rc<dyn IPlatformGraphicsContext>

A new context of the display, which shares nothing with the shared context, as in the original.

Panics

Panics when the native display cannot create a context.

fn uses_shared_context(&self) -> bool

Whether the backend renders through one context shared by all surfaces.

fn get_shared_context(&self) -> Rc<dyn IPlatformGraphicsContext>

The shared graphics context; only valid when uses_shared_context is true.

fn as_feature_provider(&self) -> Option<&dyn IOptionalFeatureProvider>

Optional features of the graphics API, if the implementation provides any.
