Node

Constructors

this

this(GNode* gNode, bool ownedRef)

Sets our main struct and passes it to the parent class.

this

this(void* data)

Creates a new #GNode containing the given data. Used to create the first node in a tree.

Destructor

~this

~this()

Undocumented in source.

Members

Functions

childIndex

int childIndex(void* data)

Gets the position of the first child of a #GNode which contains the given data.

childPosition

int childPosition(Node child)

Gets the position of a #GNode with respect to its siblings. @child must be a child of @node. The first child is numbered 0, the second 1, and so on.

childrenForeach

void childrenForeach(GTraverseFlags flags, GNodeForeachFunc func, void* data)

Calls a function for each of the children of a #GNode. Note that it doesn't descend beneath the child nodes.

copy

Node copy()

Recursively copies a #GNode (but does not deep-copy the data inside the nodes, see g_node_copy_deep() if you need that).

copyDeep

Node copyDeep(GCopyFunc copyFunc, void* data)

Recursively copies a #GNode and its data.

depth

uint depth()

Gets the depth of a #GNode.

destroy

void destroy()

Removes @root and its children from the tree, freeing any memory allocated.

find

Node find(GTraverseType order, GTraverseFlags flags, void* data)

Finds a #GNode in a tree.

findChild

Node findChild(GTraverseFlags flags, void* data)

Finds the first child of a #GNode with the given data.

firstSibling

Node firstSibling()

Gets the first sibling of a #GNode. This could possibly be the node itself.

getNodeStruct

GNode* getNodeStruct(bool transferOwnership)

Get the main Gtk struct

getRoot

Node getRoot()

Gets the root of a tree.

getStruct

void* getStruct()

the main Gtk struct as a void*

insert

Node insert(int position, Node node)

Inserts a #GNode beneath the parent at the given position.

insertAfter

Node insertAfter(Node sibling, Node node)

Inserts a #GNode beneath the parent after the given sibling.

insertBefore

Node insertBefore(Node sibling, Node node)

Inserts a #GNode beneath the parent before the given sibling.

isAncestor

bool isAncestor(Node descendant)

Returns %TRUE if @node is an ancestor of @descendant. This is true if node is the parent of @descendant, or if node is the grandparent of @descendant etc.

lastChild

Node lastChild()

Gets the last child of a #GNode.

lastSibling

Node lastSibling()

Gets the last sibling of a #GNode. This could possibly be the node itself.

maxHeight

uint maxHeight()

Gets the maximum height of all branches beneath a #GNode. This is the maximum distance from the #GNode to all leaf nodes.

nChildren

uint nChildren()

Gets the number of children of a #GNode.

nNodes

uint nNodes(GTraverseFlags flags)

Gets the number of nodes in a tree.

nthChild

Node nthChild(uint n)

Gets a child of a #GNode, using the given index. The first child is at index 0. If the index is too big, %NULL is returned.

prepend

Node prepend(Node node)

Inserts a #GNode as the first child of the given parent.

reverseChildren

void reverseChildren()

Reverses the order of the children of a #GNode. (It doesn't change the order of the grandchildren.)

traverse

void traverse(GTraverseType order, GTraverseFlags flags, int maxDepth, GNodeTraverseFunc func, void* data)

Traverses a tree starting at the given root #GNode. It calls the given function for each node visited. The traversal can be halted at any point by returning %TRUE from @func.

unlink

void unlink()

Unlinks a #GNode from a tree, resulting in two separate trees.

Properties

children

Node children [@property getter]

Node children [@property setter]

points to the first child of the #GNode. The other children are accessed by using the @next pointer of each child.

data

void* data [@property getter]

void* data [@property setter]

contains the actual data of the node.

next

Node next [@property getter]

Node next [@property setter]

points to the node's next sibling (a sibling is another #GNode with the same parent).

parent

Node parent [@property getter]

Node parent [@property setter]

points to the parent of the #GNode, or is %NULL if the #GNode is the root of the tree.

prev

Node prev [@property getter]

Node prev [@property setter]

points to the node's previous sibling.

Variables

gNode

GNode* gNode;

the main Gtk struct

ownedRef

bool ownedRef;

Undocumented in source.
