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)
