uiDeleteNode

Deletion in an uitree

Syntax

delTree = uiDeleteNode(tree, node)
delTree = uiDeleteNode(tree, position)

Input parameters

tree

uitree where we do the deletion

node

node we want to delete

position

a string, which is the position of the node we want to delete

Output parameters

delTree

an uitree without the deleted node

Description

Deletion of a node (subTree) from a tree. If we have 3 nodes called 'Node1', 'Node2' and 'Node3' each one at position 1.1, 1.2, and 1.3. Deletion of node at position 1.2 ('Node2') will pull up the 'Node 3' to position 1.2.

Examples

// We should create nodes(subTrees) before creating trees
leaf11 = uiCreateNode('leaf 1.1', 'iconLeaf1.1', 'callbackLeaf1.1')
leaf12 = uiCreateNode('leaf 1.2', 'iconLeaf1.2', 'callbackLeaf1.2')
leaf31 = uiCreateNode('leaf 3.1', 'iconLeaf3.1', 'callbackLeaf3.1')
leaf32 = uiCreateNode('leaf 3.2', 'iconLeaf3.2', 'callbackLeaf3.2')
node1 = uiCreateNode('Node 1', 'iconNode1', 'callbackNode1')
node2 = uiCreateNode('Node 2', 'iconNode2', 'callbackNode2')
node3 = uiCreateNode('Node 3', 'iconNode3', 'callbackNode3')
root = uiCreateNode('Root', 'iconRoot', 'callbackRoot')

treeNode1 = uiCreateTree(node1, leaf11, leaf12)
treeNode3 = uiCreateTree(node3, leaf31, leaf32)
treeRoot = uiCreateTree(root, treeNode1, node2, treeNode3)

// Deletion of 'node2'
treeDel = uiDeleteNode(treeRoot, node2)
uiDisplayTree(treeDel)

// Deletion of node at position '3.2'
treeDel = uiDeleteNode(treeRoot, '3.2')
uiDisplayTree(treeDel)
