uiGetParentNode — Get Parent of a node
parent = uiGetParentNode(tree, node)
parent = uiGetParentNode(tree, position)
Tree in which we look for parent of a node
the node we look for parent
a string, which is the position of the node we look for parent
// 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)
// Search parent node of 'node1'
parentNode = uiGetParentNode(treeRoot, node1)
// will return 'parentNode = root'
// Search parent node of 'leaf31'
parentNode = uiGetParentNode(treeRoot, leaf31)
// will return 'parentNode = node3'
