Node kit structure (new entries versus parent class marked with arrow prefix):.
CLASS SoSceneKit -->"this" "callbackList" --> "topSeparator" --> "cameraList" --> "lightList" --> "childList"
(See SoBaseKit::printDiagram() for information about the output formatting.)
Detailed information on catalog parts:
CLASS SoSceneKit PVT "this", SoSceneKit --- "callbackList", SoNodeKitListPart [ SoCallback, SoEventCallback ] PVT "topSeparator", SoSeparator --- "cameraList", SoNodeKitListPart [ SoCameraKit ] "lightList", SoNodeKitListPart [ SoLightKit ] "childList", SoNodeKitListPart [ SoShapeKit, SoSeparatorKit ]
(See SoBaseKit::printTable() for information about the output formatting.)
SoSceneKit::SoSceneKit | ( | void | ) |
Constructor.
SoSceneKit::~SoSceneKit | ( | ) | [protected, virtual] |
Destructor.
SoType SoSceneKit::getClassTypeId | ( | void | ) | [static] |
SoType SoSceneKit::getTypeId | ( | void | ) | const [virtual] |
Returns the type identification of an object derived from a class inheriting SoBase. This is used for run-time type checking and "downward" casting.
Usage example:
void foo(SoNode * node) { if (node->getTypeId() == SoFile::getClassTypeId()) { SoFile * filenode = (SoFile *)node; // safe downward cast, knows the type } else if (node->getTypeId().isOfType(SoGroup::getClassTypeId())) { SoGroup * group = (SoGroup *)node; // safe downward cast, knows the type } }
For application programmers wanting to extend the library with new nodes, engines, nodekits, draggers or others: this method needs to be overridden in all subclasses. This is typically done as part of setting up the full type system for extension classes, which is usually accomplished by using the pre-defined macros available through for instance Inventor/nodes/SoSubNode.h (SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes), Inventor/engines/SoSubEngine.h (for engine classes) and so on.
For more information on writing Coin extensions, see the class documentation of the toplevel superclasses for the various class groups.

const SoFieldData ** SoSceneKit::getFieldDataPtr | ( | void | ) | [static, protected] |
This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.
Reimplemented from SoBaseKit.
const SoFieldData * SoSceneKit::getFieldData | ( | void | ) | const [protected, virtual] |
Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returns NULL
.
Reimplemented from SoBaseKit.
const SoNodekitCatalog * SoSceneKit::getClassNodekitCatalog | ( | void | ) | [static] |
Returns the nodekit catalog which defines the layout of this class' kit.
Reimplemented from SoBaseKit.
const SoNodekitCatalog * SoSceneKit::getNodekitCatalog | ( | void | ) | const [virtual] |
Returns the nodekit catalog which defines the layout of this class' kit.
Reimplemented from SoBaseKit.
const SoNodekitCatalog ** SoSceneKit::getClassNodekitCatalogPtr | ( | void | ) | [static, protected] |
Returns the pointer to the pointer of the nodekit catalog for this class.
Reimplemented from SoBaseKit.
void SoSceneKit::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 SoBaseKit.

int SoSceneKit::getCameraNumber | ( | void | ) |
Returns the index of the current active camera in cameraList.
References SoBaseKit::getContainerNode(), SoSFInt32::getValue(), and SoSwitch::whichChild.
void SoSceneKit::setCameraNumber | ( | int | camnum | ) |
Sets the current active camera in cameraList.
References SoBaseKit::getContainerNode(), SoGroup::getNumChildren(), SoDebugError::postInfo(), and SoSwitch::whichChild.
SbBool SoSceneKit::affectsState | ( | void | ) | const [virtual] |
Returns TRUE
if the node could have any effect on the state during traversal.
If it returns FALSE
, no data in the traversal-state will change from the pre-traversal state to the post-traversal state. The SoSeparator node will for instance return FALSE
, as it pushes and pops the state before and after traversal of its children. All SoShape nodes will also return FALSE
, as just pushing out geometry data to the rendering engine won't affect the actual rendering state.
The default method returns TRUE
, on a "better safe than sorry" philosophy.
Reimplemented from SoNode.
