Inheritance diagram for SoNodeKitListPart:

List of all members.

## 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.

## Member Function Documentation

void SoNodeKitListPart::initClass | ( | void |  | ) | `[static]`

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

SoType SoNodeKitListPart::getContainerType | ( | void |  | ) | const

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

void SoNodeKitListPart::setContainerType | ( | SoType | newContainerType | ) |

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

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 nodetypes.

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.

SbBool SoNodeKitListPart::isTypePermitted | ( | SoType | typeToCheck | ) | const

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

SbBool SoNodeKitListPart::isChildPermitted | ( | const SoNode * | child | ) | const

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

void SoNodeKitListPart::containerSet | ( | const char * | fieldDataString | ) |

| Calls set() on the container node with fieldDataString.

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().

SbBool SoNodeKitListPart::isTypeLocked | ( | void |  | ) | const

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

void SoNodeKitListPart::addChild | ( | SoNode * | child | ) |

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

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.

SoNode * SoNodeKitListPart::getChild | ( | int | index | ) | const

| Return child node at position index.

int SoNodeKitListPart::findChild | ( | SoNode * | child | ) | const

| Return position index of child in list of children.

int SoNodeKitListPart::getNumChildren | ( | void |  | ) | const

| Return number of children.

void SoNodeKitListPart::removeChild | ( | int | index | ) |

| Remove child at position index.

void SoNodeKitListPart::removeChild | ( | SoNode * | child | ) |

| Remove child from list of children.

void SoNodeKitListPart::replaceChild | ( | int | index,
|  | SoNode * | newChild
| ) |

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

void SoNodeKitListPart::replaceChild | ( | SoNode * | oldChild,
|  | SoNode * | newChild
| ) |

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

SbBool SoNodeKitListPart::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.

SoGroup * SoNodeKitListPart::getContainerNode | ( | void |  | ) | `[protected]`

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

SbBool SoNodeKitListPart::readInstance | ( | SoInput * | in,
|  | unsigned short | flags
| ) | `[protected, virtual]`

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 / persistant 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.

void SoNodeKitListPart::copyContents | ( | const SoFieldContainer * | fromFC,
|  | 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.

Note that for simply copying e.g. a node from application code, it should be sufficient to do:

      SoNode * mynewnode = templatenode->copy();

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.
