Select all children's checkboxes in a TreeTable

Hello. I have a generated column with a checkbox in a TreeTable. How can I automatically select all children’s checkboxes when I select parent’s checkbox?

Any help is appreciated.

Thank you.

You can use getChildren() to get the collection of children’s item IDs, over which you can iterate. I don’t think you can access the generated checkboxes through the TreeTable’s API. I’ll assume that the checkboxes are
not
 generated from the container properties. You could store references to them in a HashMap<Object,CheckBox> by using the item ID as the key; add the CheckBox references there in the column generator and remove them in a DetachListener added to each CheckBox.
