Detailed Description

The SoDirectionalLightManip class is used to manipulate SoDirectionalLight nodes.

directionallight.png

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  )
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 
) const

Replaces 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.

SoSearchAction

Reimplemented from SoNode.

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

SoChildList * SoDirectionalLightManip::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 SoDirectionalLightManip::setDragger ( SoDragger newdragger) [protected]
void SoDirectionalLightManip::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.

References SoNode::copyContents(), SoNode::getClassTypeId(), getDragger(), SoBase::isOfType(), and setDragger().

void SoDirectionalLightManip::transferFieldValues ( const SoDirectionalLight from,
SoDirectionalLight to 
) [static, protected]

Copies field values.

void SoDirectionalLightManip::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.

Convert from matrix to direction.
