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 |

| 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 |

Detailed Description
Overrides the virtual methods on SoLineWidthElement to send the line width to GL when necessary.
Note that this class relies on SoLineWidthElement to store the width in the instance.
