NAME

       SoGLDisplayList -

       The SoGLDisplayList class stores and manages OpenGL display lists.

       The TEXTURE_OBJECT type is not directly supported in Coin. We handle textures differently
       in a more flexible class called SoGLImage, which also stores some information about the
       texture used when rendering. Old code which use this element should not stop working
       though. The texture object extension will just not be used, and the texture will be stored
       in a display list instead.

Constructor & Destructor Documentation

   SoGLDisplayList::SoGLDisplayList (SoState *state, Typetype, intallocnum = 1,
       SbBoolmipmaptexobj = FALSE)
       Constructor.

Member Function Documentation

   void SoGLDisplayList::ref (void)
       Increase reference count for this display list/texture object.

   void SoGLDisplayList::unref (SoState *state = NULL)
       Decrease reference count for this instance. When reference count reaches 0, the instence
       is deleted.

   void SoGLDisplayList::open (SoState *state, intindex = 0)
       Open this display list/texture object.

   void SoGLDisplayList::close (SoState *state)
       Close this display list/texture object.

   void SoGLDisplayList::call (SoState *state, intindex = 0)
       Execute this display list/texture object.

   void SoGLDisplayList::addDependency (SoState *state)
       Create a dependency on the display list.

   SbBool SoGLDisplayList::isMipMapTextureObject (void) const
       Returns whether the texture object stored in this instance was created with mipmap data.
       This method is an extension versus the Open Inventor API.

   SoGLDisplayList::Type SoGLDisplayList::getType (void) const
       Return type. Display list or texture object.

   int SoGLDisplayList::getNumAllocated (void) const
       Return number of display lists/texture objects allocated.

   unsigned int SoGLDisplayList::getFirstIndex (void) const
       Return first GL index for this display list.

   int SoGLDisplayList::getContext (void) const
       Return an id for the current context.

   void SoGLDisplayList::setTextureTarget (inttarget)
       Sets the texture object target

       Since:
           Coin 2.5

   int SoGLDisplayList::getTextureTarget (void) const
       Returns the texture target

       Since:
           Coin 2.5
