if i remember correctly setChecked functions only if the node is not
rendered
after you have to use toggleCheck
so the correct code is:
node.eachChild(new NodeTraversalCallback() {
public boolean execute(Node node) {
((TreeNode)node).getUI().toggleCheck(true);//true if you want
the node to be checked
}
});
i have tried it myself and functions correctly ;)...
