TreeNode

Constructors

this

this(DzlTreeNode* dzlTreeNode, bool ownedRef = false)

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

this

this()

Creates a new #DzlTreeNode instance. This is handy for situations where you do not want to subclass #DzlTreeNode.

getIconName

string getIconName()

Fetches the icon-name of the icon to display, or NULL for no icon.

getItem

ObjectG getItem()

Gets a #GObject for the node, if one was set.

getParent

TreeNode getParent()

Retrieves the parent #DzlTreeNode for @node.

getPath

TreePath getPath()

Gets a #GtkTreePath for @node.

getResetOnCollapse

bool getResetOnCollapse()

getStruct

void* getStruct()

the main Gtk struct as a void*

getText

string getText()

getTree

Tree getTree()

Fetches the #DzlTree instance that owns the node.

getTreeNodeStruct

DzlTreeNode* getTreeNodeStruct(bool transferOwnership = false)

Get the main Gtk struct

getUseDimLabel

bool getUseDimLabel()

getUseMarkup

bool getUseMarkup()

hasEmblem

bool hasEmblem(string emblemName)

Checks to see if @emblem_name has been added to the #DzlTreeNode.

insert

void insert(TreeNode child, uint position)

Inserts @child as a child of @self at @position.

insertSorted

void insertSorted(TreeNode child, DzlTreeNodeCompareFunc compareFunc, void* userData)

Inserts a @child as a child of @node, sorting it among the other children.

invalidate

void invalidate()

isRoot

bool isRoot()

nChildren

uint nChildren()

nthChild

TreeNode nthChild(uint nth)

Gets the @nth child of @self or %NULL if it does not exist.

prepend

void prepend(TreeNode child)

Prepends @child to the list of children owned by @node.

rebuild

void rebuild()

Rebuilds a node, without invalidating children nodes. If you want to ensure that children are also rebuilt, use dzl_tree_node_invalidate().

remove

void remove(TreeNode child)

Removes @child from the list of children owned by @node.

removeEmblem

void removeEmblem(string emblemName)

select

void select()

setChildrenPossible

void setChildrenPossible(bool childrenPossible)

If the node has not yet been built, setting this to %TRUE will add a dummy child node. This dummy node will be removed when when the node is built by the registered #DzlTreeBuilder instances.

setEmblems

void setEmblems(string emblems)

setForegroundRgba

void setForegroundRgba(RGBA foregroundRgba)

Sets the foreground-rgba to be used by the row text.

setGicon

void setGicon(IconIF icon)

setIconName

void setIconName(string iconName)

Sets the icon name of the node. This is displayed in the pixbuf cell of the DzlTree.

setItem

void setItem(ObjectG item)

An optional object to associate with the node. This is handy to save needing to subclass the #DzlTreeNode class.

setResetOnCollapse

void setResetOnCollapse(bool resetOnCollapse)

setText

void setText(string text)

Sets the text of the node. This is displayed in the text cell of the DzlTree.

setUseDimLabel

void setUseDimLabel(bool useDimLabel)

setUseMarkup

void setUseMarkup(bool useMarkup)

showPopover
