This field is used where nodes, engines or other field containers need to store multiple color values (i.e. "Red Green Blue" triplets). This field supports application data sharing through a setValuesPointer() method. See **SoMField** documentation for information on how to use this function. **See also** **SbColor4f**, **SoSFColorRGBA** ## Member Function Documentation ### void \* SoMFColorRGBA::createInstance (void ) \[static\] *This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.*\ Creates a new instance of the class type corresponding to the **SoType** object. ### SoType SoMFColorRGBA::getClassTypeId (void ) \[static\] This static method returns the **SoType** object associated with objects of this class. ### SoType SoMFColorRGBA::getTypeId (void ) const \[virtual\] Returns the type identification of an object derived from a class inheriting **SoField**. This is used for runtime type checking and "downward" casting. Implements **SoField**. ### void SoMFColorRGBA::copyFrom (const SoField & f) \[virtual\] Copy value(s) from *f* into this field. *f* must be of the same type as this field. Implements **SoField**. ### SbBool SoMFColorRGBA::isSame (const SoField & f) const \[virtual\] Check for equal type and value(s). Implements **SoField**. ### void SoMFColorRGBA::deleteAllValues (void ) \[protected\], \[virtual\] *This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.*\ Implements **SoMField**. ### void SoMFColorRGBA::copyValue (int to, int from) \[protected\], \[virtual\] This method is used for moving values around internally within a multivalue field. It needs to be overridden in each field so it automatically takes care of running copy constructors where necessary. Implements **SoMField**. ### const SbColor4f \* SoMFColorRGBA::getValues (const int start) const \[inline\] Returns a pointer to the values array. ### void SoMFColorRGBA::initClass (void ) \[static\] Internal method called upon initialization of the library (from **SoDB::init()**) to set up the type system. ### void SoMFColorRGBA::setValues (int start, int numarg, const float rgba\[\]\[4\]) Set *num* RGB color values, starting at index *start*. ### void SoMFColorRGBA::setHSVValues (int start, int numarg, const float hsva\[\]\[4\]) Set *num* HSV color values, starting at index *start*. ### void SoMFColorRGBA::setValue (const SbVec4f & vec) Set the color array to a single value. *vec* is interpreted as a three element vector with the red, green and blue components, respectively. ### void SoMFColorRGBA::setValue (float r, float g, float b, float a) Set the color array to a single value. *r*, *g* and *b* are the red, green and blue components, respectively. ### void SoMFColorRGBA::setValue (const float rgba\[4\]) Set the color array to a single value. *rgb* is a three element vector with the red, green and blue components, respectively. ### void SoMFColorRGBA::setHSVValue (float h, float s, float v, float a) Set the color array to a single value. *h*, *s* and *v* are the hue, saturation and value components, respectively. ### void SoMFColorRGBA::setHSVValue (const float hsva\[4\]) Set the color array to a single value. *hsv* is a three element vector with the hue, saturation and value components, respectively. ### void SoMFColorRGBA::set1Value (int idx, const SbVec4f & vec) Set the color at *idx*. *vec* is interpreted as a three element vector with the red, green and blue components, respectively. ### void SoMFColorRGBA::set1Value (int idx, float r, float g, float b, float a) Set the color at *idx*. *r*, *g* and *b* is the red, green and blue components, respectively. ### void SoMFColorRGBA::set1Value (int idx, const float rgba\[4\]) Set the color at *idx*. *rgb* is interpreted as a three element vector with the red, green and blue components, respectively. ### void SoMFColorRGBA::set1HSVValue (int idx, float h, float s, float v, float a) Set the color at *idx*. *h*, *s* and *v* is the hue, saturation and value components, respectively. ### void SoMFColorRGBA::set1HSVValue (int idx, const float hsva\[4\]) Set the color at *idx*. *hsv* is a three element vector with the hue, saturation and value components, respectively. ## Author Generated automatically by Doxygen for Coin from the source code.
