NSOpenSets or gets the swap interval.
NSOpenGet or set the surface order.
NSOpenSet or get the surface opacity.
NSOpenSet or get the height and width of the back buffer. You can use this to let the system scale an image automatically on swapping to a variable-size buffer. The back buffer size remains fixed at the size that you set up regardless of whether the image is resized to display larger onscreen.
NSOpenEnable or disable reclaiming resources.
NSOpenThe current renderer ID. You can get this setting.
NSOpenThe CPU is currently processing vertices with the GPU. You can get this state.
NSOpenThe CPU is currently processing fragments with the GPU. You can get this state.
NSOpenReturns a Boolean that indicates whether a drawable is attached to the context.
NSOpenThe number of frames that the multithreaded OpenGL engine can process before stalling. The default value is 1. New frames are queued when the application calls the flush method. A larger number may improve overall performance, but adds latency between when a frame is rendered and when a frame is displayed. Interactive applications should leave this value at the default.
NSOpenSets or gets the swap rectangle.
NSOpenEnables or disables the swap rectangle in the context’s drawable object.
NSOpenIf disabled, all rasterization of 2D and 3D primitives is disabled.
NSOpenIf enabled, OpenGL inspects the context state each time the update method is called to ensure that it is in an appropriate state for switching between renderers.
