Inheritance diagram for SoGLPointSizeElement:

Public Member Functions
virtual void	init (SoState *state)
	Initializes element.
virtual void	push (SoState *state)
	Override push() method to copy state pointer and value of previous element, to avoid sending GL commands if the elements are the same.
virtual void	pop (SoState *state, const SoElement *prevTopElement)
	Override pop() method so side effects can occur in GL.
virtual void	init (SoState *state)
	Initializes element.
Public Member Functions inherited from SoFloatElement
virtual bool	matches (const SoElement *elt) const
	Comparison based on value of floats.
virtual SoElement *	copyMatchInfo () const
	Copy method, takes care copying the data.
virtual void	print (FILE *fp) const
	Prints element (for debugging)
Public Member Functions inherited from SoElement
virtual void	init (SoState *state)
	Initializes element.
virtual void	push (SoState *state)
	Pushes/pops element.
virtual void	pop (SoState *state, const SoElement *prevTopElement)
virtual void	print (FILE *fp) const
	Prints element (for debugging)
virtual bool	matches (const SoElement *elt) const =0
	Returns TRUE if the element matches another element (of the same class, presumably) with respect to cache validity.
virtual SoElement *	copyMatchInfo () const =0
	Create a copy that we can put in a cache used list and call matches() on later.
SoType	getTypeId () const
	Returns type identifier for element instance.
int	getStackIndex () const
	Returns the stack index for an element instance.
void	setDepth (int dpth)
	Sets stuff in an element instance.
void	setNext (SoElement *nxt)
void	setNextInStack (SoElement *nxt)
void	setNextFree (SoElement *nxt)
int	getDepth () const
	Returns stuff from element instance.
SoElement *	getNext () const
virtual	~SoElement ()
	Destructor.

Detailed Description

Overrides the virtual methods on SoPointSizeElement to send the point size to GL when necessary.
