addChild() [1/2]

static void addChild ( SceneNode::Ptr  child, GroupNode::Ptr  parent, AddPolicy  policy = Back  )

static

add a child to the groupnode parent

Parameters

child	[in] the child to add
parent	[in] the parent
policy	[in] add it to the front or the back

addChild() [2/2]

void addChild	(	SceneNode::Ptr	node,
		AddPolicy	policy = Back
	)

add a child to this group node

Parameters

node	[in] the child to add
policy	[in] add it to the front or the back

asGroupNode()

GroupNode* asGroupNode ( )

virtual

Get a pointer to a GroupNode, if this is a GroupNode.

Returns

a pointer, or NULL if the SceneNode is not of correct type.

Reimplemented from SceneNode.

hasChild() [1/2]

bool hasChild

(

const std::string &

nodename

)

test if this group node has a child node with name nodename

Parameters

nodename

[in] name of child node

Returns

true if nodename is child of this, false otherwise

hasChild() [2/2]

bool hasChild

(

SceneNode::Ptr

node

)

test if this group node has the node node as child

Parameters

node	[in] a scene node

Returns

true if node is child of this, false otherwise

removeChild() [1/2]

void removeChild

(

const std::string &

name

)

remove node with name name from the children list of this node AND removes this node from the parent list of node.

Parameters

name	[in] child node that is to be removed

removeChild() [2/2]

void removeChild

(

SceneNode::Ptr

node

)

remove node from the children list of this node AND removes this node from the parent list of node.

Parameters

node	[in] child node that is to be removed
