Detailed Description
The SoDirectionalLightManip class is used to manipulate SoDirectionalLight nodes.
A manipulator is used by replacing the node you want to edit in the graph with the manipulator. Draggers are used to manipulate the node. When manipulation is finished, the node is put back into the graph, replacing the manipulator.
Constructor & Destructor Documentation
SoDirectionalLightManip::SoDirectionalLightManip (void)The constructor sets up the internal SoDiretionalLightDragger used by the manipulator.
References children, colorFieldSensor, directionFieldSensor, fieldSensorCB(), setDragger(), and SoDelayQueueSensor::setPriority().
SoDirectionalLightManip::~SoDirectionalLightManip () [protected]Destructor. Clean up resources used by manipulator.

Member Function Documentation
void SoDirectionalLightManip::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 SoDirectionalLight.
Referenced by SoInteraction::init().
SoDragger * SoDirectionalLightManip::getDragger (void)Return pointer to internal SoDirectionalLightDragger dragger.
References children, SoNode::getClassTypeId(), SbPList::getLength(), SoBase::isOfType(), and SoDebugError::post().
Referenced by fieldSensorCB(), and setDragger().
SbBool SoDirectionalLightManip::replaceNode (SoPath * path)Replaces the node specified by path with this manipulator. The manipulator will copy the field data from the node, to make it affect the state in the same way as the node.
References fieldSensorCB(), SoNode::getClassTypeId(), SoFullPath::getLength(), SoFullPath::getNodeFromTail(), SoBaseKit::getPart(), SoBaseKit::getPartString(), SoPath::getTail(), SoFullPath::getTail(), SoBase::isOfType(), SoDebugError::post(), SoBase::ref(), SoBaseKit::setPart(), transferFieldValues(), and SoBase::unrefNoDelete().
SbBool SoDirectionalLightManip::replaceManip (SoPath * path, SoDirectionalLight * newone) constReplaces this manipulator from the position specified by path with newnode. If newnode is NULL, an SoDirectionalLight will be created for you.
void SoDirectionalLightManip::doAction (SoAction * action) [virtual]This function performs the typical operation of a node for any action.
Reimplemented from SoNode.
References children, SoAction::getPathCode(), SoChildList::traverse(), and SoChildList::traverseInPath().
Referenced by callback(), GLRender(), handleEvent(), pick(), and search().
void SoDirectionalLightManip::callback (SoCallbackAction * action) [virtual]Action method for SoCallbackAction.
Simply updates the state according to how the node behaves for the render action, so the application programmer can use the SoCallbackAction for extracting information about the scene graph.
Reimplemented from SoLight.
References doAction().
void SoDirectionalLightManip::GLRender (SoGLRenderAction * action) [virtual]Action method for the SoGLRenderAction.
This is called during rendering traversals. Nodes influencing the rendering state in any way or who wants to throw geometry primitives at OpenGL overrides this method.
Reimplemented from SoDirectionalLight.
References doAction().
void SoDirectionalLightManip::getBoundingBox (SoGetBoundingBoxAction * action) [virtual]Action method for the SoGetBoundingBoxAction.
Calculates bounding box and center coordinates for node and modifies the values of the action to encompass the bounding box for this node and to shift the center point for the scene more towards the one for this node.
Nodes influencing how geometry nodes calculates their bounding box also overrides this method to change the relevant state variables.
Reimplemented from SoNode.
References children, SoGetBoundingBoxAction::getCenter(), SbPList::getLength(), SoAction::getPathCode(), SoGetBoundingBoxAction::isCenterSet(), SoGetBoundingBoxAction::resetCenter(), SoGetBoundingBoxAction::setCenter(), and SoChildList::traverse().
void SoDirectionalLightManip::getMatrix (SoGetMatrixAction * action) [virtual]Action method for SoGetMatrixAction.
Updates action by accumulating with the transformation matrix of this node (if any).
Reimplemented from SoNode.
References children, SoAction::getPathCode(), SoChildList::traverse(), and SoChildList::traverseInPath().
void SoDirectionalLightManip::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 SoNode.
References doAction().
void SoDirectionalLightManip::pick (SoPickAction * action) [virtual]Action method for SoPickAction.
Does common processing for SoPickAction action instances.
Reimplemented from SoNode.
References doAction().
void SoDirectionalLightManip::search (SoSearchAction * action) [virtual]Action method for SoSearchAction.
Compares the search criteria from the action to see if this node is a match. Searching is done by matching up all criteria set up in the SoSearchAction -- if any of the requested criteria is a miss, the search is not deemed successful for the node.
