Public Member Functions

virtual void init (SoState *state)
 Initializes element.
 
virtual void push (SoState *state)
 Override push() so we can remember the previous element's draw style, and perhaps avoid sending unnecessary GL calls if this element is the same.
 
virtual void pop (SoState *state, const SoElement *prevTopElement)
 Override pop() method so side effects can occur in GL.
 
- Public Member Functions inherited from SoDrawStyleElement
virtual void init (SoState *state)
 Initializes element.
 
virtual void print (FILE *fp) const
 Prints element (for debugging)
 
- Public Member Functions inherited from SoInt32Element
virtual bool matches (const SoElement *elt) const
 Comparison based on value of int32_ts.
 
virtual SoElement * copyMatchInfo () const
 Copy method, takes care copying the data.
 
virtual void setElt (int32_t value)

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

SoType getTypeId () const
 Returns type identifier for element instance.
 
int getStackIndex () const
 Returns the stack index for an element instance.

Detailed Description

Overrides the virtual methods on SoDrawStyleElement to send the draw style to GL when necessary.

Note that this class relies on SoDrawStyleElement to store the style in the instance.

Also note that this tells GL only how to draw polygons. Shapes that contain lines still have to check for POINTS draw styles and act accordingly.
