Altering Node Selection

Selecting Nodes

• The currently selected node in an AdvancedTree instance may be accessed at any time using the selectedNode property, which returns a reference to a TreeNode instance.

// sets id attribute of selected node
tree.selectedNode.setAttribute("id", 99);

• selectedNode can be set as well, which changes the node currently selected in an AdvancedTree instance.

// removes all selected nodes and sets new selected
tree.selectedNode = tree.rootNode;

• If selectMultiple has been set to true for an AdvancedTree instance, then the selected list of nodes can be accessed using selectedNodes, which returns an array of TreeNode instances.

// removes all selected nodes
var nodes:Array = tree.selectedNodes;
for each (var treeNode:TreeNode in nodes) tree.removeNode(treeNode);
tree.refresh();

• The AdvancedTree method openToAndSelect will open the AdvancedTree instance to the specified node and select it. If any of the other selection methods are used for a node that is not visible, the selection will not be visible.

// opens the tree to the specified node and selects it
tree.openToAndSelect(tree.rootNode.firstChild);

Deselecting Nodes

• The currently selected node may be deselected using the AdvancedTree method deselectNode, which takes a TreeNode instance.

// deselects the current selected node
tree.deselectNode(tree.selectedNode);

• When selectMultiple is set to true on an AdvancedTree instance, deselectAll is useful for deselecting all currently selected nodes.

// deselects nodes in tree
tree.deselectAll();
