Expand Flex tree by clicking row

This is cool, useful and easy. It allows the user to opne a tree branch by clicking anywhere in the parent row (not just the arrow icon):

import mx.events.ListEvent;

private function tree_itemClick(evt:ListEvent):void {
var item:Object = Tree(evt.currentTarget).selectedItem;
if (mytree.dataDescriptor.isBranch(item)) {
mytree.expandItem(item, !mytree.isItemOpen(item), true);
}
}

...
itemClick="tree_itemClick(event);" />
