SoLineWidthElement(3) Coin SoLineWidthElement(3) NAME
SoLineWidthElement - The SoLineWidthElement class changes the linewidth setting of the render state. Requests from the scenegraph to change the linewidth when rendering line primitives will be made through this element, which forwards it to the appropriate native call in the underlying rendering library. SYNOPSIS
#include <Inventor/elements/SoLineWidthElement.h> Inherits SoFloatElement. Inherited by SoGLLineWidthElement. Public Member Functions virtual void init (SoState *state) Static Public Member Functions static SoType getClassTypeId (void) static int getClassStackIndex (void) static void * createInstance (void) static void initClass (void) static void set (SoState *const state, SoNode *const node, const float lineWidth) static void set (SoState *const state, const float lineWidth) static float get (SoState *const state) static float getDefault () Protected Member Functions virtual ~SoLineWidthElement () Additional Inherited Members Detailed Description The SoLineWidthElement class changes the linewidth setting of the render state. Requests from the scenegraph to change the linewidth when rendering line primitives will be made through this element, which forwards it to the appropriate native call in the underlying rendering library. Subsequent nodes rendering line primitives will use the width setting (for instance SoLineSet nodes).

SoFloatElement(3) Coin SoFloatElement(3) NAME
SoFloatElement - SoFloatElement is an abstract base class for elements that consists of a single float value. This is the superclass of elements where the new element data replaces the old data, and where the data the element stores is a simple single precision floating point value. SYNOPSIS
#include <Inventor/elements/SoFloatElement.h> Inherits SoElement. Inherited by SoComplexityElement, SoCreaseAngleElement, SoDecimationPercentageElement, SoFocalDistanceElement, SoFontSizeElement, SoLineWidthElement, SoListenerGainElement, SoPointSizeElement, and SoTextureQualityElement.

This is the superclass of elements where the new element data replaces the old data, and where the data the element stores is a simple single precision floating point value. This element is like a convenient light-weight version of the SoReplacedElement. It differs from the SoReplacedElement in that the set() and get() methods are already implemented, since it is known that subclasses will still contain just a single float value.

It is called for the first element of each enabled element type in SoState objects. Reimplemented from SoElement.

SbBool SoFloatElement::matches (const SoElement *element) const [virtual] This function returns TRUE is the element matches another element (of the same class), with respect to cache validity. If the application programmer's extension element has a matches() function, it should also have a copyMatchInfo() function. Implements SoElement. SoElement * SoFloatElement::copyMatchInfo (void) const [virtual] This function creates a copy of the element that contains enough information to enable the matches() function to work. Used to help with scenegraph traversal caching operations. Implements SoElement. void SoFloatElement::print (FILE *file) const [virtual] This function is for printing element information, and is used mostly for debugging purposes. Reimplemented from SoElement. void SoFloatElement::set (const intstackIndex, SoState *conststate, const floatvalue) [static] Static method for setting the value of an element in the given state at the given stackIndex. float SoFloatElement::get (const intindex, SoState *conststate) [static] Static method to fetch the value of the element of this type from the given state at the given stack index. void SoFloatElement::setElt (floatvalue) [virtual] Set element value. Reimplemented in SoGLPointSizeElement, and SoGLLineWidthElement. Member Data Documentation float SoFloatElement::data [protected] The element's value.
