Hello,
I am trying to get a tree component to 'show up'. I copied and pasted the
code from this article
http://www.macromedia.com/devnet/mx/trio/articles/tree_control03.html, (See
below) and dragged a tree component onto the stage and named it 'myTree_tree'.
When I test this, nothing shows up, just the empty listbox thing. I traced
the tree component and it returned a reference to it - so its named correctly.
Does anyone have any very simple tree code that I can test just to get the
tree to 'show up' ?

// This code will create a simple, static tree.
// Set the root node to display "Parts List" and be initially open.
// To do this we create a new tree node object in a variable called //
'myRootNode' and then pass it to myTree_tree through the
// setRootNode() method of the Tree Control component.
var myRootNode = new FTreeNode("Parts List").setIsOpen(true);
myTree_tree.setRootNode(myRootNode);
// Next set the first parent node by creating another node object
// in a variable called 'parentnode1' and passing it to myRootNode
// through the addNode() method of the Tree Control component.
var parentnode1 = new FTreeNode("All Wheel Drive","parentnode1data");
myRootNode.addNode(parentnode1);
// We'll repeat the process to create a child node, passing the node
// object to the parentnode1 we just created.
var childnode1 = new FTreeNode("Axel Shaft","childnode1 data");
parentnode1.addNode(childnode1);
// The next two addNode() routines simply repeat the procedure above
// to build out the tree with more parts.
var parentnode2 = new FTreeNode("Cooling","parentnode2 data");
myRootNode.addNode(parentnode2);
var childnode2 = new FTreeNode("Pump Block","childnode2 data");
parentnode2.addNode(childnode2);
// Finally, we need to refresh the tree to display the node we created.
myTree_tree.refresh();
