Class

NSOpenGLLayer

A subclass of CAOpenGLLayer that is suitable for rendering OpenGL into layers.

Declaration

class NSOpenGLLayer : CAOpenGLLayer

Overview

Unlike CAOpenGLLayer, NSOpenGLLayer uses AppKit types.

Topics

Drawing the Content

func canDraw(in: NSOpenGLContext, pixelFormat: NSOpenGLPixelFormat, forLayerTime: CFTimeInterval, displayTime: UnsafePointer<CVTimeStamp>) -> Bool

Invoked to ask the layer whether it can (or should) draw.

func draw(in: NSOpenGLContext, pixelFormat: NSOpenGLPixelFormat, forLayerTime: CFTimeInterval, displayTime: UnsafePointer<CVTimeStamp>)

Draws the OpenGL content for the specified time.

Managing the Pixel Format

var openGLPixelFormat: NSOpenGLPixelFormat?

Provides access to the layer's associated NSOpenGLPixelFormat.

func openGLPixelFormat(forDisplayMask: UInt32) -> NSOpenGLPixelFormat

Returns the OpenGL pixel format suitable for the specified displays.

Managing the Rendering Context

var openGLContext: NSOpenGLContext?

The layer’s NSOpenGLContext.

func openGLContext(for: NSOpenGLPixelFormat) -> NSOpenGLContext

Returns the OpenGL context to use for the requested pixel format.

Accessing the Associated View

var view: NSView?

Returns the view associated with the layer.
