Constructor & Destructor Documentation

◆ ~SoSoundElement()

SoSoundElement::~SoSoundElement ( void  )
protectedvirtual

The destructor.

Member Function Documentation

◆ createInstance()

void * SoSoundElement::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.

◆ initClass()

void SoSoundElement::initClass ( void  )
static

This static method initializes static data for the SoSoundElement class.

◆ init()

void SoSoundElement::init ( SoState *  state)
virtual

Initializes the element to it's default value.

Reimplemented from SoReplacedElement.

◆ set()

void SoSoundElement::set ( SoState *const  state,
SoNode *const  node,
SbBool  scenegraphhassoundnode,
SbBool  soundnodeisplaying,
SbBool  ispartofactivescenegraph 
)
static

Sets the flags.

◆ setSceneGraphHasSoundNode()

SbBool SoSoundElement::setSceneGraphHasSoundNode ( SoState *const  state,
SoNode *const  node,
SbBool  flag 
)
static

Sets the sceneGraphHasSoundNode flag.

◆ sceneGraphHasSoundNode()

SbBool SoSoundElement::sceneGraphHasSoundNode ( SoState *const  state)
static

The sceneGraphHasSoundNode flag is used to stop the SoAudioRenderAction in SoSeparator and SoVRMLGroup nodes for cases where the sub-graph doesn not contain any SoVRMLSound nodes.

Returns the value of the sceneGraphHasSoundNode flag.

◆ setSoundNodeIsPlaying()

SbBool SoSoundElement::setSoundNodeIsPlaying ( SoState *const  state,
SoNode *const  node,
SbBool  flag 
)
static

Sets the soundNodeIsPlaying flag.

◆ soundNodeIsPlaying()

SbBool SoSoundElement::soundNodeIsPlaying ( SoState *const  state)
static

The soundNodeIsPlaying flag is currently unused.

Returns the value of the soundNodeIsPlaying flag.

◆ setIsPartOfActiveSceneGraph()

SbBool SoSoundElement::setIsPartOfActiveSceneGraph ( SoState *const  state,
SoNode *const  node,
SbBool  flag 
)
static

Sets the isPartOfActiveSceneGraph flag.

◆ isPartOfActiveSceneGraph()

SbBool SoSoundElement::isPartOfActiveSceneGraph ( SoState *const  state)
static

The isPartOfActiveSceneGraph flag is used to make SoVRMLSound that are below inactive parts of the scenegraph (i.e. below a SoSwitch or SoLOD node) stop playing.

Returns the value of the isPartOfActiveSceneGraph flag.

◆ push()

void SoSoundElement::push ( SoState *  state)
virtual

Calls the superclass' push method. Initializes the element to the default values. Uses previous element's isPartOfActiveSceneGraph flag.

Reimplemented from SoElement.

◆ pop()

void SoSoundElement::pop ( SoState *  state,
const SoElement *  prevTopElement 
)
virtual

Calls the superclass' pop method.

Reimplemented from SoElement.

◆ setDefaultValues()

void SoSoundElement::setDefaultValues ( )
protected

Initializes the element to the default values. The default values for the sceneGraphHasSoundNode is FALSE. The default value for the isPartOfActiveSceneGraph flag is TRUE. the default value for the soundNodeIsPlaying flag is FALSE.
