Constructors

glContextNew Source

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

Methods

glContextGetGLDrawable Source

:: 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 Source

Gets the GLConfig with which the GLContext is configured.

glContextGetShareList :: GLContext -> IO GLContext Source

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

glContextIsDirect :: GLContext -> IO Bool Source

Returns whether the GLContext is a direct rendering context.

glContextGetRenderType :: GLContext -> IO GLRenderType Source

Gets the GLRenderType of the GLContext.

glContextGetCurrent Source

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