Detailed Description

The SoPointLightManip class is used to manipulate point light nodes.

 

A manipulator is used by replacing the node you want to edit in the graph with the manipulator. Draggers are used to to manipulate the node. When manipulation is finished, the node is put back into the graph, replacing the manipulator.

Constructor & Destructor Documentation

SoPointLightManip::SoPointLightManip (void)The constructor. Creates a default dragger.

Member Function Documentation

void SoPointLightManip::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 SoPointLight.

Referenced by SoInteraction::init().

SoDragger * SoPointLightManip::getDragger (void)Returns the current dragger.

References children, SoNode::getClassTypeId(), SbPList::getLength(), SoBase::isOfType(), and SoDebugError::post().

Referenced by fieldSensorCB(), and setDragger().

SbBool SoPointLightManip::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 SoPointLightManip::replaceManip (SoPath * path, SoPointLight * newone) constReplaces this manipulator from the position specified by path with newnode. If newnode is NULL, an SoPointLight will be created for you.

void SoPointLightManip::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 SoPointLightManip::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 SoPointLightManip::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 SoPointLight.

References doAction().

void SoPointLightManip::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 SoPointLightManip::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 SoPointLightManip::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 SoPointLightManip::pick (SoPickAction * action) [virtual]Action method for SoPickAction.

Does common processing for SoPickAction action instances.

Reimplemented from SoNode.

References doAction().

void SoPointLightManip::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.

SoSearchAction

Reimplemented from SoNode.

References doAction(), SoSearchAction::isFound(), and SoNode::search().

SoChildList * SoPointLightManip::getChildren (void) const [virtual]Returns the children of this node. This node only has the dragger as a child.

Reimplemented from SoNode.

References children.

void SoPointLightManip::setDragger (SoDragger * newdragger) [protected]The method can be used to replace the dragger with your own dragger.

void SoPointLightManip::transferFieldValues (const SoPointLight * from, SoPointLight * to) [static, protected]This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

Copies field values.
