Methods

CreateFromSurface()

Create and OpenGL context for a surface.

Declaration
public OpenGLContextHandle CreateFromSurface()
Returns
Type Description
OpenGLContextHandle

An OpenGL context handle.

CreateFromWindow(WindowHandle)

Create an OpenGL context for a window.

Declaration
public OpenGLContextHandle CreateFromWindow(WindowHandle handle)
Parameters
Type Name Description
WindowHandle handle

The window for which the OpenGL context should be created.
Returns
Type Description
OpenGLContextHandle

An OpenGL context handle.
See Also

DestroyContext(OpenGLContextHandle)

Destroy an OpenGL context.

Declaration
public void DestroyContext(OpenGLContextHandle handle)
Parameters
Type Name Description
OpenGLContextHandle handle

Handle to the OpenGL context to destroy.
See Also

GetBindingsContext(OpenGLContextHandle)

Gets a IBindingsContext from an OpenGLContextHandle. Pass this to LoadBindings(IBindingsContext) to load the OpenGL bindings.

Declaration
public IBindingsContext GetBindingsContext(OpenGLContextHandle handle)
Parameters
Type Name Description
OpenGLContextHandle handle

The handle to get a bindings context for.
Returns
Type Description
IBindingsContext

The created bindings context.
See Also

GetContextValues(OpenGLContextHandle)

Gets the context values of the OpenGL context. This can be used to query the actually selected context values initially requested in OpenGLGraphicsApiHints.

Declaration
public ContextValues GetContextValues(OpenGLContextHandle handle)
Parameters
Type Name Description
OpenGLContextHandle handle

The OpenGL context to get the context values from.
Returns
Type Description
ContextValues

The context values for the OpenGL context.
Remarks

During context creation all possible context values are enumerated and sent to Selector (by default set to DefaultValuesSelector(IReadOnlyList<ContextValues>, ContextValues, ILogger?)) which can choose the an appropriate format. This function returns these selected values.

GetCurrentContext()

Get the current OpenGL context for this thread.

Declaration
public OpenGLContextHandle? GetCurrentContext()
Returns
Type Description
OpenGLContextHandle

Handle to the current OpenGL context, null if no context is current.
See Also

GetNSOpenGLContext(OpenGLContextHandle)

Returns the NSOpenGLContext associated with the specified context handle.

Declaration
public nint GetNSOpenGLContext(OpenGLContextHandle handle)
Parameters
Type Name Description
OpenGLContextHandle handle

A handle to an OpenGL context to get the associated NSOpenGLContext from.
Returns
Type Description
nint

The NSOpenGLContext associated with the context handle.

GetProcedureAddress(OpenGLContextHandle, string)

Get the procedure address for an OpenGL command.

Declaration
public nint GetProcedureAddress(OpenGLContextHandle handle, string procedureName)
Parameters
Type Name Description
