JTree open folder on single click

Question

I have a custom tree that expands JTree and would like the folders to open/close on a single click rather than a double click (per user requirements). Should I do this with a mouse listener and based on the node do something, or is there another way? Also, how can I programatically toggle a folder node opened/closed state?
Thanks!

Thanks!Here's one way:
someTree.getSelectionModel().addTreeSelectionListener(new TreeSelectionListener() {
            public void valueChanged(TreeSelectionEvent e) {
                if (!someTree.isExpanded(someTree.getSelectionModel().getLeadSelectionRow())) {
                    someTree.expandPath(e.getNewLeadSelectionPath());
        });
