var myTreeNode:XMLNode = myTreeDP.firstChild;
myTreeNode.addTreeNode("Inbox", 1);
myTreeNode.addTreeNode("Outbox", 2);
myTreeNode.addTreeNode("Sent Items", 3);
myTreeNode.addTreeNode("Deleted Items", 4);
// Assign the myTreeDP data source to the myTree component
myTree.dataProvider = myTreeDP;
// Set each of the four child nodes to be branches
for (var i = 0; i<myTreeNode.childNodes.length; i++) {
var node:XMLNode = myTreeNode.getTreeNodeAt(i);
myTree.setIsBranch(node, true);
