uiDeleteNode

Deletion in a Tree

Calling Sequence

delTree = uiDeleteNode(tree, node)

delTree = uiDeleteNode(tree, position)

Input parameters

tree: Tree were 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: a Tree 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)
