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¶

SoType SoFloatElement::getClassTypeId (void) [static]¶
This static method returns the class type. Reimplemented from SoElement. Reimplemented in SoGLPointSizeElement, SoComplexityElement, SoCreaseAngleElement, SoDecimationPercentageElement, SoFocalDistanceElement, SoFontSizeElement, SoGLLineWidthElement, SoLineWidthElement, SoListenerGainElement, SoPointSizeElement, and SoTextureQualityElement.int SoFloatElement::getClassStackIndex (void) [static]¶
This static method returns the state stack index for the class. Reimplemented from SoElement. Reimplemented in SoGLPointSizeElement, SoComplexityElement, SoCreaseAngleElement, SoDecimationPercentageElement, SoFocalDistanceElement, SoFontSizeElement, SoGLLineWidthElement, SoLineWidthElement, SoListenerGainElement, SoPointSizeElement, and SoTextureQualityElement.void SoFloatElement::initClass (void) [static]¶
Initialize relevant common data for all instances, like the type system. Reimplemented from SoElement. Reimplemented in SoGLPointSizeElement, SoComplexityElement, SoCreaseAngleElement, SoDecimationPercentageElement, SoFocalDistanceElement, SoFontSizeElement, SoGLLineWidthElement, SoLineWidthElement, SoListenerGainElement, SoPointSizeElement, and SoTextureQualityElement.void SoFloatElement::init (SoState *state) [virtual]¶
This function initializes the element type in the given SoState. It is called for the first element of each enabled element type in SoState objects. Reimplemented from SoElement. Reimplemented in SoGLPointSizeElement, SoComplexityElement, SoCreaseAngleElement, SoDecimationPercentageElement, SoFocalDistanceElement, SoFontSizeElement, SoGLLineWidthElement, SoLineWidthElement, SoListenerGainElement, SoPointSizeElement, and SoTextureQualityElement.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.Author¶
