Andi Huber commented on ISIS-1944:
----------------------------------
Demo of TreeNode creation and programmatic node expansion (not showing the
MyTreeAdapter class).
{code:java}
@ViewModel
public static class RootNode {
public String title() {
return "Hello World";
}
}
@Action
public TreeNode<Object> tree() {
val root = new RootNode();
val tree = TreeNode.lazy(root, MyTreeAdapter.class);
tree.expand(TreePath.of(0), TreePath.of(0, 0));
return tree;
}
{code}
> Tree View: allow programmatic expand/collapse of tree-nodes
