You can ask the node if it is a leave or not. See the API documentation
of TreeNode.

Do you mean how to know when something is selected or if the something
selected is a node or not? If you mean the first, use this:

myTree.addTreeSelectionListener(new TreeSelectionListener()
{
public void valueChanged(TreeSelectionEvent evt)
{
TreePath path = this.getSelectionPath();
if (path != null)
{
DefaultMutableTreeNode node =
(DefaultMutableTreeNode)path.getLastPathComponent();
if (node.isLeaf())
{
// do child stuff
}
else
{
// do parent stuff
}

}
}
});


Hope that helps.
Matthew
