Altering Node Selection

Selecting Nodes

• The currently selected node in a 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);

• selectNode can be set as well, which changes the node currently selected in a advancedTree instance.

// removes all selected nodes
tree.selectedNode = tree.rootNode;

• If selectMultiple has been set to true for a 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 (var i:String in nodes) tree.removeNode(nodes[i]);
tree.refresh();

• The advancedTree method selectAndOpen 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.selectAndOpen(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 a advancedTree instance, deselectAll is useful for deselecting all currently selected nodes.

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