o

Returns

The number of direct children of this node.

Defined in MinSG/Core/Nodes/GroupNode.h:36

function
MinSG::GroupNode::addChild

public
     
     
void addChild( Util::Reference < Node > child )

Add a child to this node and update the child’s parent.

  • May throw an exception on failure

Defined in MinSG/Core/Nodes/GroupNode.h:40

function
MinSG::GroupNode::hasChildren

public const inline
   
   
bool hasChildren( ) const

Defined in MinSG/Core/Nodes/GroupNode.h:42

function
MinSG::GroupNode::removeChild

public
     
     
bool removeChild( Util::Reference < Node > child )

Try to remove a child from this node.

Returns

trueifchildwas removed.

Defined in MinSG/Core/Nodes/GroupNode.h:46

function
MinSG::GroupNode::doRemoveChild

public virtual
     
     
bool doRemoveChild( Util::Reference < Node > child )

(internal) Remove the given child from this node.

  • called by removeChild(…).

  • Has to set the child’s parent to null (child->_setParent(nullptr)).

    Returns

    false iff the node could not be found.

Note: Normally, use removeChild(…) instead.

Defined in MinSG/Core/Nodes/GroupNode.h:55

function
MinSG::GroupNode::invalidateCompoundBB

public virtual
   
   
void invalidateCompoundBB( )

This method is called by Node::worldBBChanged() for all parent nodes (until one has a fixed bb). If the node’s bounding box is influenced by its children, it should be invalidated here and then re-calculated on the next call of doGetBB().

Defined in MinSG/Core/Nodes/GroupNode.h:62

function
MinSG::GroupNode::removeFixedBB

public inline virtual
   
   
void removeFixedBB( )
> Node

Defined in MinSG/Core/Nodes/GroupNode.h:65

function
MinSG::GroupNode::clearChildren

public
   
   
void clearChildren( )

Removes all children from the Node .
