Description The SoLocateHighlight class highlights geometry under the cursor. Note: this node is supposed to draw to the front buffer. However, in Coin we always draw to the back buffer, forcing a scene redraw whenever a highlight state changes. FILE FORMAT/DEFAULTS: LocateHighlight { renderCaching AUTO boundingBoxCaching AUTO renderCulling AUTO pickCulling AUTO color 0.3 0.3 0.3 style EMISSIVE mode AUTO } Member Enumeration Documentation enum SoLocateHighlight::Modes Enum type for behaviour modes. Enumerator AUTO Highlight when mouse cursor is over the contents of the node. ON Always highlight. OFF Never highlight. enum SoLocateHighlight::Styles Enum type for highlight styles. Enumerator EMISSIVE Highlight using emissive color override. EMISSIVE_DIFFUSE Highlight using emissive and diffuse color override. Constructor & Destructor Documentation SoLocateHighlight::SoLocateHighlight (void) Constructor. SoLocateHighlight::~SoLocateHighlight () [protected], [virtual] Destructor. Member Function Documentation SoType SoLocateHighlight::getClassTypeId (void) [static] This static method returns the SoType object associated with objects of this class. SoType SoLocateHighlight::getTypeId (void) const [virtual] Returns the type identification of an object derived from a class inheriting SoBase. This is used for runtime type checking and 'downward' casting. Reimplemented from SoSeparator. Reimplemented in SoWWWAnchor. const SoFieldData ** SoLocateHighlight::getFieldDataPtr (void) [static], [protected] This API member is considered internal to the library, as it is not likely to be of interest to the application programmer. Returns the SoFieldData class which holds information about fields in this node. const SoFieldData * SoLocateHighlight::getFieldData (void) const [protected], [virtual] Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returns NULL. 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 override 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() does 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. Reimplemented from SoSeparator. 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. Reimplemented in SoWWWAnchor. Member Data Documentation SoSFColor SoLocateHighlight::color The color used for highlighting. Default is [0.3, 0.3, 0.3], a dark gray. SoSFEnum SoLocateHighlight::style The highlight style. Default is SoLocateHighlight::EMISSIVE. SoSFEnum SoLocateHighlight::mode The highlight mode. Default is SoLocateHighlight::AUTO. Author Generated automatically by Doxygen for Coin from the source code. Version 4.0.2 Tue Dec 26 2023 17:59:22 SoLocateHighlight(3)
