Detailed Description

The SoPointLightDragger class provides interactive geometry for manipulating a point light source.

Here's how the dragger looks with its default geometry in the inactive state:

Screen Shot of Default Dragger

This dragger is well suited to use for setting up the fields of a SoPointLight node, as it provides geometry for the end-user to translate a point in 3D space.

The Coin library also includes a manipulator class, SoPointLightManip, which wraps the functionality provided by this class inside the necessary mechanisms for connecting it to SoPointLight node instances in a scene graph.

See also: SoPointLightManip

Constructor & Destructor Documentation

◆ SoPointLightDragger()

SoPointLightDragger::SoPointLightDragger ( void )

Default constructor, sets up the dragger nodekit catalog with the interaction and feedback geometry.

Nodekit structure (new entries versus parent class marked with arrow prefix):

CLASS SoPointLightDragger
-->"this"
      "callbackList"
      "topSeparator"
         "motionMatrix"
-->      "material"
-->      "translator"
         "geomSeparator"

(See SoBaseKit::printDiagram() for information about the output formatting.)

Detailed information on catalog parts:

CLASS SoPointLightDragger
PVT   "this",  SoPointLightDragger  --- 
      "callbackList",  SoNodeKitListPart [ SoCallback, SoEventCallback ] 
PVT   "topSeparator",  SoSeparator  --- 
PVT   "motionMatrix",  SoMatrixTransform  --- 
      "material",  SoMaterial  --- 
      "translator",  SoDragPointDragger  --- 
PVT   "geomSeparator",  SoSeparator  ---

(See SoBaseKit::printTable() for information about the output formatting.)

◆ ~SoPointLightDragger()

SoPointLightDragger::~SoPointLightDragger ( void )

protectedvirtual

Protected destructor.

(Dragger classes are derived from SoBase, so they are reference counted and automatically destroyed when their reference count goes to 0.)

Member Function Documentation

◆ fieldSensorCB()

void SoPointLightDragger::fieldSensorCB	(	void *	d,
		SoSensor *	s )

staticprotected

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

◆ getClassNodekitCatalog()

const SoNodekitCatalog * SoPointLightDragger::getClassNodekitCatalog ( void )

static

Returns the nodekit catalog which defines the layout of this class' kit.

◆ getClassNodekitCatalogPtr()

const SoNodekitCatalog ** SoPointLightDragger::getClassNodekitCatalogPtr ( void )

staticprotected

Returns the pointer to the pointer of the nodekit catalog for this class.

◆ getClassTypeId()

SoType SoPointLightDragger::getClassTypeId ( void )

static

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

◆ getFieldData()

const SoFieldData * SoPointLightDragger::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 SoDragger.

◆ getFieldDataPtr()

const SoFieldData ** SoPointLightDragger::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.

◆ getNodekitCatalog()

const SoNodekitCatalog * SoPointLightDragger::getNodekitCatalog ( void ) const

virtual

Returns the nodekit catalog which defines the layout of this class' kit.

Reimplemented from SoDragger.

◆ getTypeId()

SoType SoPointLightDragger::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 SoDragger.

◆ initClass()

void SoPointLightDragger::initClass ( void )

static

Initializes type system for this dragger class.

Application programmers should usually not have to invoke this method, see documentation of SoInteraction::init().

◆ setDefaultOnNonWritingFields()

void SoPointLightDragger::setDefaultOnNonWritingFields ( void )

protectedvirtual

(Be aware that this method is unlikely to be of interest to the application programmer who does not want to extend the library with new custom nodekits or draggers. If you indeed are writing extensions, see the information in the SoBaseKit class documentation.)

This is a virtual method, and the code in it should call SoField::setDefault() with argument TRUE on part fields that should not be written upon scene graph export operations.

This is typically done when:

field value is NULL and part is NULL by default
it is a leaf SoGroup or SoSeparator node with no children
it is a leaf listpart with no children and an SoGroup or SoSeparator container
it is a non-leaf part and it is of SoGroup type and all fields are at their default values

Subclasses should usually override this to do additional settings for new member fields. From the subclass, do remember to call "upwards" to your superclass' setDefaultOnNonWritingFields() method.

Reimplemented from SoDragger.

◆ setUpConnections()

SbBool SoPointLightDragger::setUpConnections	(	SbBool	onoff,
		SbBool	doitalways = FALSE )

protectedvirtual

Sets up all internal connections for instances of this class.

(This method will usually not be of interest to the application programmer, unless you want to extend the library with new custom nodekits or dragger classes. If so, see the SoBaseKit class documentation.)

Reimplemented from SoInteractionKit.

◆ valueChangedCB()

void SoPointLightDragger::valueChangedCB	(	void *	f,
		SoDragger *	d )

staticprotected

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

Member Data Documentation

◆ translation

SoSFVec3f SoPointLightDragger::translation

This field is continuously updated to contain the translation of the point light dragger. The application programmer will typically connect this to the SoPointLight::location field of a SoPointLight node (unless using the SoPointLightManip class, where this is taken care of automatically).

It may also of course be connected to any other location / translation field controlling the position of scene graph geometry, it does not have to part of a SoPointLight node specifically.

The documentation for this class was generated from the following files:

SoPointLightDragger.h
SoPointLightDragger.cpp
