Class Avogadro::Rendering::GroupNode#

class Avogadro::Rendering::GroupNode : public Node#

The GroupNode class provides common API for grouping child nodes.

The GroupNode may be used to group items together, but for most other purposes a more derived Node type would be the correct choice.

void addChild(Node *node, NodeType ui = NodeType::GEOMETRY)#

Add a child node, this node will have its parent set and will be deleted by this node upon destruction.

Parameters

nodeNode to be added.

void addUIChild(Node *node)#

Add a child node, this node will have its parent set and will be deleted by this node upon destruction.

Parameters

nodeNode to be added.

bool removeChild(Node *node)#

Remove child node, this node will no longer be deleted.

Parameters

nodeNode to be removed.

Returns

True if the node was removed, false if it was not found.

Node *child(size_t index)#

Get the child Node at the specified index.

Parameters

index – The index of the child.

Returns

A pointer to the child node, or nullptr if the index is out of range. time complexity: O(n)

bool hasChild(Node *node) const#

check if the Node exists in this GroupNode.

Parameters

nodeNode to search.

Returns

True if the node was found, false otherwise.

inline size_t childCount() const#
Returns

The number of child nodes contained by the GroupNode.

inline std::list<NodeInfo> &children()#

Get a reference to the child nodes list.

inline const std::list<NodeInfo> &children() const#
