IGraphicsContext and IGraphicsContextInternal implementation for iPhoneOS.

public class iPhoneOSGraphicsContext : IDisposable, OpenTK.Graphics.IGraphicsContext, OpenTK.Graphics.IGraphicsContextInternal

type iPhoneOSGraphicsContext = class
    interface IGraphicsContext
    interface IDisposable
    interface IGraphicsContextInternal

Inheritance: Object
iPhoneOSGraphicsContext

Implements: IGraphicsContext IGraphicsContextInternal IDisposable

Remarks

Instances of this class are implicitly created by GraphicsContext. This type cannot be directly created by the developer.

The primary purpose for this type is to obtain access to the wrapped EAGLContext instance, which may need to be used in certain circumstances. If you have a GraphicsContext instance as returned by CreateGraphicsContext(EAGLRenderingAPI), you can obtain the wrapped EAGLContext instance by doing:

var context = ...
    // e.g. Utilities.CreateGraphicsContext(EAGLRenderingAPI.OpenGLES1);
var internalGC = context as IGraphicsContextInternal;
iPhoneOSGraphicsContext iPhoneGC = internalGC.Implementation as iPhoneOSGraphicsContext;
if (iPhoneGC != null) {
    EAGLContext eaglContext = iPhoneGC.Context;
}

Alternatively, use iPhoneOSGameView as your base type, and use EAGLContext to obtain the wrapped EAGLContext.

Properties

EAGLContext	Gets the EAGLContext.
ErrorChecking	Whether automatic error checking should be performed on GL calls.
GraphicsMode	The format for graphics operations.
IsCurrent	Gets a value indicating whether this graphics context is the current graphics context.
IsDisposed
VSync	This member is not supported.

Methods

Dispose()	Releases all resources used by the iPhoneOSGraphicsContext.
Dispose(Boolean)	Releases all resources used by the iPhoneOSGraphicsContext.
Finalize()	Releases unmanaged resources.
MakeCurrent(IWindowInfo)
SwapBuffers()	Swap buffers, presenting the rendered scene to the user.
Update(IWindowInfo)

Explicit Interface Implementations
