How to implement filtering for treetableview

Question

Can anyone please suggest me how to implement filtering for a TreeTableView component? I am using jdk 1.8.20

Answer 1

Use a FilteredList, for example:

ObservableList data = FxCollections.observableArrayList();
FilteredList filtered = data.filtered(p->p.getAge()>21)
treetableview.setItems(filtered)
