Constructors

glConfigNew

:: [GLConfigMode] mode - display mode bit mask. -> IO GLConfig Returns an OpenGL frame buffer configuration that match the specified display mode.

glConfigNewForScreen

:: Screen screen - target screen. -> [GLConfigMode] mode - display mode. -> IO GLConfig Returns an OpenGL frame buffer configuration that matchs the specified display mode.

Methods

glConfigGetScreen

:: GLConfig -> IO Screen returns the Screen. Gets the Screen associated with the GLConfig.

glConfigGetColormap

:: GLConfig -> IO Colormap returns the appropriate Colormap. Gets the Colormap that is appropriate for the OpenGL frame buffer configuration.

glConfigGetDepth

:: GLConfig -> IO Int returns number of bits per pixel Gets the color depth of the OpenGL-capable visual.

glConfigGetLayerPlane

:: GLConfig -> IO Int returns layer plane. Gets the layer plane (level) of the frame buffer. Zero is the default frame buffer. Positive layer planes correspond to frame buffers that overlay the default buffer, and negative layer planes correspond to frame buffers that underlie the default frame buffer.

glConfigGetNAuxBuffers

:: GLConfig -> IO Int returns number of auxiliary color buffers. Gets the number of auxiliary color buffers.

glConfigGetNSampleBuffers

:: GLConfig -> IO Int returns number of multisample buffers. Gets the number of multisample buffers.

glConfigIsRgba

:: GLConfig -> IO Bool returns True if the configured frame buffer is RGBA mode, False otherwise. Returns whether the configured frame buffer is RGBA mode.

glConfigIsDoubleBuffered

:: GLConfig -> IO Bool returns True if the double-buffered visual is supported, False otherwise. Returns whether the configuration supports the double-buffered visual.

glConfigIsStereo

:: GLConfig -> IO Bool returns True if the stereo visual is supported, False otherwise. Returns whether the configuration supports the stereo visual.

glConfigHasAlpha

:: GLConfig -> IO Bool returns True if the color buffer has alpha bits, False otherwise. Returns whether the configured color buffer has alpha bits.

glConfigHasDepthBuffer

:: GLConfig -> IO Bool returns True if the frame buffer has depth buffer, False otherwise. Returns whether the configured frame buffer has depth buffer.

glConfigHasStencilBuffer

:: GLConfig -> IO Bool returns True if the frame buffer has stencil buffer, False otherwise. Returns whether the configured frame buffer has stencil buffer.

glConfigHasAccumBuffer

:: GLConfig -> IO Bool returns True if the frame buffer has accumulation buffer, False otherwise. Returns whether the configured frame buffer has accumulation buffer.
