Constructors

glContextNew

:: GLDrawableClass gldrawable => gldrawable gldrawable - a GLDrawable. -> Maybe GLContext shareList - the GLContext with which to share display lists and texture objects. A value of Nothing indicates that no sharing is to take place. -> Bool direct - whether rendering is to be done with a direct connection to the graphics system. -> GLRenderType renderType - RGBAType or ColorIndexType (currently not used). -> IO GLContext Creates a new OpenGL rendering context.

Methods

glContextGetGLDrawable

:: GLContext -> IO GLDrawable returns the GLDrawable or Nothing if no GLDrawable is bound. Gets GLDrawable to which the GLContext is bound.

glContextGetGLConfig :: GLContext -> IO GLConfig

Gets the GLConfig with which the GLContext is configured.

glContextGetShareList :: GLContext -> IO GLContext

Gets the other GLContext with which the GLContext shares the display lists and texture objects.

glContextIsDirect :: GLContext -> IO Bool

Returns whether the GLContext is a direct rendering context.

glContextGetRenderType :: GLContext -> IO GLRenderType

Gets the GLRenderType of the GLContext.

glContextGetCurrent

:: IO (Maybe GLContext) returns the current GLContext or Nothing if there is no current context. Returns the current GLContext.
