NAME

       SoGLColorIndexElement -

       The SoGLColorIndexElement class sets the current OpenGL color.

       This element is only used when the OpenGL canvas is in colorindex mode, ie where colors for individual pixels are fetched from a color
       lookup table ('CLUT'). The usual thing to do is to set up a canvas in RGBA truecolor mode.

Detailed Description
       The SoGLColorIndexElement class sets the current OpenGL color.

       This element is only used when the OpenGL canvas is in colorindex mode, ie where colors for individual pixels are fetched from a color
       lookup table ('CLUT'). The usual thing to do is to set up a canvas in RGBA truecolor mode.

       One common use for colorindex mode OpenGL canvases is to use one in the overlay planes (which are usually limited to only 2 or 4 available
       colors), if supported by the OpenGL hardware and / or driver.

Member Function Documentation
   SoType SoGLColorIndexElement::getClassTypeId (void) [static]
       This static method returns the class type.

       Reimplemented from SoReplacedElement.

   int SoGLColorIndexElement::getClassStackIndex (void) [static]
       This static method returns the state stack index for the class.

       Reimplemented from SoReplacedElement.

   void * SoGLColorIndexElement::createInstance (void) [static]
       This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

   void SoGLColorIndexElement::initClass (void) [static]
       Initialize relevant common data for all instances, like the type system.

       Reimplemented from SoReplacedElement.

   SbBool SoGLColorIndexElement::isColorIndexMode (SoState *state) [static]
       Returns TRUE if the current GL context is in color index mode.

   void SoGLColorIndexElement::init (SoState *state) [virtual]
       This function initializes the element type in the given SoState. It is called for the first element of each enabled element type in SoState
       objects.

       Reimplemented from SoReplacedElement.

   void SoGLColorIndexElement::set (SoState *conststate, SoNode *constnode, const int32_tnumindices, const int32_t *constindices) [static]
       Sets current color indices.

   const SoGLColorIndexElement * SoGLColorIndexElement::getInstance (SoState *state) [static]
       Returns the current element.

   int32_t SoGLColorIndexElement::getNum (void) const
       Returns number of color indices in element.
