Detailed Description

The SoNodeKitListPart class is a container node.

This node is basically just a container node with these differences versus the other group nodes:

  1. It is possible to make a list of which node class types are allowed as children.
  2. You can freely select which kind of group node behaviour you want this container to have. Default is to act like an SoGroup node, but by using SoNodeKitListPart::setContainerType(), you can change the behaviour to be like a separator, a switch or whatever else you have of node types inheriting SoGroup.

It might be necessary to get the container node, e.g. to change SoSwitch::whichChild if the container node is a SoSwitch. The container node is located in the first position of its children, i.e. (*getChildren())[0]. Note that getNumChildren() returns 0, while getChildren()->getLength() returns 1 after initialization. The former amount returns its internal group nodes, while the latter returns all the nodes containing the container node.

Member Function Documentation

◆ getTypeId()

SoType SoNodeKitListPart::getTypeId ( void  ) const

Returns the type identification of an object derived from a class inheriting SoBase. This is used for runtime 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

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 predefined 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 top level superclasses for the various class groups.

Implements SoBase.

◆ getFieldData()

const SoFieldData * SoNodeKitListPart::getFieldData ( void  ) const

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

Reimplemented from SoFieldContainer.

◆ initClass()

void SoNodeKitListPart::initClass ( void  )

Does initialization common for all objects of the SoNodeKitListPart class. This includes setting up the type system, among other things.

◆ getContainerType()

SoType SoNodeKitListPart::getContainerType ( void  ) const

Return type id for the list container. Default is SoGroup.

◆ setContainerType()

void SoNodeKitListPart::setContainerType ( SoType  newContainerType)

Change the behaviour of this container node. newContainerType must be derived from SoGroup.

◆ getChildTypes()

const SoTypeList & SoNodeKitListPart::getChildTypes ( void  ) const

Return a list of all types which are allowed as children of this node. Default is to allow all node types.

◆ addChildType()

void SoNodeKitListPart::addChildType ( SoType  typeToAdd)

Add one more node class type which should be allowed to be used in the node list.

Note: the default single SoNode type in the list will be removed upon the first call to this method.

◆ isTypePermitted()

SbBool SoNodeKitListPart::isTypePermitted ( SoType  typeToCheck) const

Return TRUE if nodes of the typeToCheck class type can be added to the list.

◆ isChildPermitted()

SbBool SoNodeKitListPart::isChildPermitted ( const SoNode child) const

Return TRUE if child has a class type which is permitted to be in the list.

◆ containerSet()

void SoNodeKitListPart::containerSet ( const char *  fieldDataString)

Calls set() on the container node with fieldDataString.

◆ lockTypes()

void SoNodeKitListPart::lockTypes ( void  )

Lock type list so no more node class types can be added by using addChildType(), and locks container type so it no longer can be changed by setContainerType().

◆ isTypeLocked()

SbBool SoNodeKitListPart::isTypeLocked ( void  ) const

Returns TRUE if the list of allowable node types and the container type have both been locked.

◆ addChild()

void SoNodeKitListPart::addChild ( SoNode child)

Adds child to the internal list of children, if it is of a type permitted to be added.

◆ insertChild()

void SoNodeKitListPart::insertChild ( SoNode child,
int  childIndex 

Inserts child in the internal list of children at position childIndex, if it is of a type permitted to be added.

◆ getChild()

SoNode * SoNodeKitListPart::getChild ( int  index) const

Return child node at position index.

◆ findChild()

int SoNodeKitListPart::findChild ( SoNode child) const

Return position index of child in list of children.

◆ getNumChildren()

int SoNodeKitListPart::getNumChildren ( void  ) const

Return number of children.

◆ removeChild() [1/2]

void SoNodeKitListPart::removeChild ( int  index)

Remove node at childindex in our list of children.

Please note that this method is not virtual in the original SGI Inventor API.

◆ removeChild() [2/2]

void SoNodeKitListPart::removeChild ( SoNode child)

Remove child from the set of children managed by this group node. Will decrease the reference count of child by 1.

This is a convenience method. It will simply call findChild() with child as argument, and then call removeChild(int) if the child is found.

Please note that this method is not virtual in the original SGI Inventor API.

◆ replaceChild() [1/2]

void SoNodeKitListPart::replaceChild ( int  index,
SoNode newChild 

Replace child at index with newChild, if newChild is of a permitted type.

◆ replaceChild() [2/2]

void SoNodeKitListPart::replaceChild ( SoNode oldChild,
SoNode newChild 

Replace oldChild with newChild, if newChild is of a permitted type.

◆ affectsState()

SbBool SoNodeKitListPart::affectsState ( void  ) const

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.

◆ doAction()

void SoNodeKitListPart::doAction ( SoAction action)

This just "forwards" the call to the same method at the container node.

Reimplemented from SoNode.

◆ callback()

void SoNodeKitListPart::callback ( SoCallbackAction action)

This just "forwards" the call to the same method at the container node.

This just "forwards" the call to the same method at the container node.

Reimplemented from SoNode.

◆ getBoundingBox()

void SoNodeKitListPart::getBoundingBox ( SoGetBoundingBoxAction action)

This just "forwards" the call to the same method at the container node.

Reimplemented from SoNode.

◆ getMatrix()

void SoNodeKitListPart::getMatrix ( SoGetMatrixAction action)

This just "forwards" the call to the same method at the container node.

Reimplemented from SoNode.

◆ handleEvent()

void SoNodeKitListPart::handleEvent ( SoHandleEventAction action)

This just "forwards" the call to the same method at the container node.

Reimplemented from SoNode.

◆ pick()

void SoNodeKitListPart::pick ( SoPickAction action)

This just "forwards" the call to the same method at the container node.

void SoNodeKitListPart::search ( SoSearchAction action)

This just "forwards" the call to the same method at the container node.

Reimplemented from SoNode.

◆ getPrimitiveCount()

void SoNodeKitListPart::getPrimitiveCount ( SoGetPrimitiveCountAction action)

This just "forwards" the call to the same method at the container node.

Reimplemented from SoNode.

◆ getChildren()

SoChildList * SoNodeKitListPart::getChildren ( void  ) const

This just "forwards" the call to the same method at the container node.

Reimplemented from SoNode.

◆ getContainerNode()

SoGroup * SoNodeKitListPart::getContainerNode ( void  )

Return the SoGroup container which is the parent of all the children which have been added.

◆ readInstance()

SbBool SoNodeKitListPart::readInstance ( SoInput in,
unsigned short  flags 

This method is mainly intended for internal use during file import operations.

It reads a definition of an instance from the input stream in. The input stream state points to the start of a serialized / persistent representation of an instance of this class type.

TRUE or FALSE is returned, depending on if the instantiation and configuration of the new object of this class type went OK or not. The import process should be robust and handle corrupted input streams by returning FALSE.

flags is used internally during binary import when reading user extension nodes, group nodes or engines.

Reimplemented from SoNode.

◆ copyContents()

void SoNodeKitListPart::copyContents ( const SoFieldContainer from,
SbBool  copyconnections 

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();

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:

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.
