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.
   SoPointLightManip::~SoPointLightManip (void) [protected, virtual] The
       destructor.

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.

   SoDragger * SoPointLightManip::getDragger (void) Returns the current
       dragger.
       See also:
           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.
   SbBool SoPointLightManip::replaceManip (SoPath * path, SoPointLight *
       newone) const Replaces 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.

   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.

   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.

   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.

   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.

   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.

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

       Reimplemented from SoNode.

   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.

       See also:
           SoSearchAction

       Reimplemented from SoNode.

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

   void SoPointLightManip::setDragger (SoDragger * newdragger) [protected] The
       method can be used to replace the dragger with your own dragger.
   void SoPointLightManip::copyContents (const SoFieldContainer * from, SbBool
       copyconnections) [protected, virtual] Makes a deep copy of all data of
       from into this instance, except external scenegraph references if
       copyconnections is FALSE.
       This is the protected method that should be overridden by extension
       node / engine / dragger / whatever subclasses which needs to account
       for internal data that are not handled automatically.

       For copying nodes from application code, you should not invoke this
       function directly, but rather call the SoNode::copy() function:

         SoNode * mynewnode = templatenode->copy();

       The same also goes for engines.

       Make sure that when you override the copyContents() method in your
       extension class that you also make it call upwards to it’s parent
       superclass in the inheritance hierarchy, as copyContents() in for
       instance SoNode and SoFieldContainer does important work. It should go
       something like this:

         void
         MyCoinExtensionNode::copyContents(const SoFieldContainer * from,
                                           SbBool copyconnections)
         {
           // let parent superclasses do their thing (copy fields, copy
           // instance name, etc etc)
           SoNode::copyContents(from, copyconnections);

           // [..then copy internal data..]
         }

       Reimplemented from SoNode.

   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.

   void SoPointLightManip::valueChangedCB (void * m, SoDragger * dragger)
       [static, protected] This API member is considered internal to the
       library, as it is not likely to be of interest to the application
       programmer.
   void SoPointLightManip::fieldSensorCB (void * m, SoSensor * d) [static,
       protected] This API member is considered internal to the library, as it
       is not likely to be of interest to the application programmer.
