SoLocateHighlight::SoLocateHighlight | ( | void | ) |
SoLocateHighlight::~SoLocateHighlight | ( | ) | [protected, virtual] |
Destructor.
void SoLocateHighlight::initClass | ( | void | ) | [static] |
Sets up initialization for data common to all instances of this class, like submitting necessary information to the Coin type system.
Reimplemented from SoSeparator.
Reimplemented in SoWWWAnchor.
void SoLocateHighlight::handleEvent | ( | SoHandleEventAction * | action | ) | [virtual] |
Action method for SoHandleEventAction.
Inspects the event data from action, and processes it if it is something which this node should react to.
Nodes influencing relevant state variables for how event handling is done also overrides this method.
Reimplemented from SoSeparator.
Reimplemented in SoWWWAnchor.

void SoLocateHighlight::GLRenderBelowPath | ( | SoGLRenderAction * | action | ) | [virtual] |
SGI Open Inventor v2.1 obsoleted support for SoGLRenderAction::addMethod(). Instead, GLRender() might be called directly, and to optimize traversal, the SoSeparator node calls GLRenderBelowPath whenever the path code is BELOW_PATH or NO_PATH (path code is guaranteed not to change). To be compatible with SGI's Inventor (and thereby also TGS') we have chosen to follow their implementation in this respect.
SoSeparator::GLRenderBelowPath() do not traverse its children using SoChildList::traverse(), but calls GLRenderBelowPath() directly for all its children.
Reimplemented from SoSeparator.

void SoLocateHighlight::GLRenderInPath | ( | SoGLRenderAction * | action | ) | [virtual] |
Implements the SoAction::IN_PATH traversal method for the rendering action.

void SoLocateHighlight::turnOffCurrentHighlight | ( | SoGLRenderAction * | action | ) | [static] |
Static method that can be used to turn off the current highlight.
void SoLocateHighlight::redrawHighlighted | ( | SoAction * | act, |
SbBool | flag | ||
) | [protected, virtual] |
Empty method in Coin. Can be used by subclasses to be told when status change.
