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!

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