Quick JTree Question...

Is there a way to set a treeNode that does not currently contain any childern with the closedFolderIcon instead of the leafIcon?
If I created a node that allows childern, but is currently empty, I would like to display this node with the closedFolderIcon. This would be similar to an empty directory within a file system.
I plan on having a "Add Folder" and "Add Node" button to manipulate the tree.
When I add a rootNode to the JTree I get a leafIcon instead of the closedFolderIcon. I only get the closedFolderIcon once I have added a childNode to the rootNode.
Any ideas?
