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

addChild()

void SoNodeKitListPart::addChild

(

SoNode *

child

)

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

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.

affectsState()

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.

callback()

void SoNodeKitListPart::callback ( SoCallbackAction * action )

virtual

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

Reimplemented from SoNode.

containerSet()

void SoNodeKitListPart::containerSet

(

const char *

fieldDataString

)

Calls set() on the container node with fieldDataString.

copyContents()

void SoNodeKitListPart::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();

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.

static

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

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.

isChildPermitted()

readInstance()

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

protectedvirtual

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.

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.

search()

void SoNodeKitListPart::search ( SoSearchAction * action )

virtual

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

Reimplemented from SoNode.

setContainerType()

void SoNodeKitListPart::setContainerType

(

SoType

newContainerType

)

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