- 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, int index = 0)Open this display list/texture object.
- void SoGLDisplayList::close (SoState * state)Close this display list/texture object.
- void SoGLDisplayList::call (SoState * state, int index = 0)Execute this display list/texture object.
- void SoGLDisplayList::addDependency (SoState * state)Create a dependency on the display list.
- SbBool SoGLDisplayList::isMipMapTextureObject (void) constReturns 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) constReturn type. Display list or texture object.
- int SoGLDisplayList::getNumAllocated (void) constReturn number of display lists/texture objects allocated.
- unsigned int SoGLDisplayList::getFirstIndex (void) constReturn first GL index for this display list.
- int SoGLDisplayList::getContext (void) constReturn an id for the current context.
- void SoGLDisplayList::setTextureTarget (int target)Sets the texture object target
- int SoGLDisplayList::getTextureTarget (void) constReturns the texture target

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.
