Detailed Description

The SoSpotLightManip class is used to manipulate spot light 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.

Example of SpotLight Manipulator

Constructor & Destructor Documentation

◆ SoSpotLightManip()

SoSpotLightManip::SoSpotLightManip ( void )

The constructor sets up the internal SoSpotLightDragger used for manipulation.

◆ ~SoSpotLightManip()

SoSpotLightManip::~SoSpotLightManip ( void )

protectedvirtual

Destructor.

Member Function Documentation

◆ callback()

void SoSpotLightManip::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.

◆ copyContents()

void SoSpotLightManip::copyContents	(	const SoFieldContainer *	from,
		SbBool	copyconnections )

protectedvirtual

Makes a deep copy of all data of from into this instance, except external scene graph references if copyconnections is FALSE.

This is the method that should be overridden by extension node / engine / dragger / whatever subclasses which need 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();

SbList

The SbList class is a template container class for lists.

Definition SbList.h:70

SbList::copy

void copy(const SbList< Type > &l)

Definition SbList.h:92

SoNode

The SoNode class is the base class for nodes used in scene graphs.

Definition SoNode.h:56

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 its 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.)
  SoNode::copyContents(from, copyconnections);
 
  // [..then copy internal data..]
}

Reimplemented from SoNode.

◆ doAction()

void SoSpotLightManip::doAction ( SoAction * action )

virtual

This function performs the typical operation of a node for any action.

Reimplemented from SoNode.

◆ fieldSensorCB()

void SoSpotLightManip::fieldSensorCB	(	void *	m,
		SoSensor *	d )

staticprotected

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

Updates the dragger whenever a field is modified.

◆ getBoundingBox()

void SoSpotLightManip::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 calculate their bounding box also override this method to change the relevant state variables.

Reimplemented from SoNode.

◆ getChildren()

SoChildList * SoSpotLightManip::getChildren ( void ) const

virtual

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

Returns the children of this node. This node only has the dragger as a child.

Reimplemented from SoNode.

◆ getClassTypeId()

SoType SoSpotLightManip::getClassTypeId ( void )

static

This static method returns the SoType object associated with objects of this class.

◆ getDragger()

SoDragger * SoSpotLightManip::getDragger ( void )

Returns pointer to internal dragger.

◆ getFieldData()

const SoFieldData * SoSpotLightManip::getFieldData ( void ) const

protectedvirtual

Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returns NULL.

Reimplemented from SoSpotLight.

◆ getFieldDataPtr()

const SoFieldData ** SoSpotLightManip::getFieldDataPtr ( void )

staticprotected

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.

◆ getMatrix()

void SoSpotLightManip::getMatrix ( SoGetMatrixAction * action )

virtual

Action method for SoGetMatrixAction.

Updates action by accumulating with the transformation matrix of this node (if any).

Reimplemented from SoNode.

◆ getTypeId()

SoType SoSpotLightManip::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 SoSpotLight.

◆ GLRender()

void SoSpotLightManip::GLRender ( SoGLRenderAction * action )

virtual

Action method for the SoGLRenderAction.

This is called during rendering traversals. Nodes influencing the rendering state in any way or want to throw geometry primitives at OpenGL override this method.

Reimplemented from SoSpotLight.

◆ handleEvent()

void SoSpotLightManip::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 SoNode.

◆ pick()

void SoSpotLightManip::pick ( SoPickAction * action )

virtual

Action method for SoPickAction.

Does common processing for SoPickAction action instances.

Reimplemented from SoNode.

◆ replaceManip()

SbBool SoSpotLightManip::replaceManip	(	SoPath *	path,
		SoSpotLight *	newone ) const

Replaces this manipulator from the position specified by path with newnode. If newnode is NULL, an SoSpotLight will be created for you.

◆ replaceNode()

SbBool SoSpotLightManip::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.

◆ search()

void SoSpotLightManip::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.

◆ setDragger()

void SoSpotLightManip::setDragger ( SoDragger * newdragger )

protected

Set dragger to use for user interaction.

◆ transferFieldValues()

void SoSpotLightManip::transferFieldValues	(	const SoSpotLight *	from,
		SoSpotLight *	to )

staticprotected

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.

◆ valueChangedCB()

void SoSpotLightManip::valueChangedCB	(	void *	m,
		SoDragger *	dragger )

staticprotected

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

Updates the fields when the motion matrix changes.
