@Override public void updateItem(T item, boolean empty) { super.updateItem(item, empty); if(empty) { setText(null); setGraphic(null); } else if(item instanceof Node) { setText(null); Node currentNode = getGraphic(); Node newNode = (Node) item; if(currentNode == null || !currentNode.equals(newNode)) { setGraphic(newNode); } } else { setText(item == null ?

While we will * lazily instantiate it we never clear it, being more * afraid of object churn than a minor "leak" (which * will not become a "major" leak). */ setText(item == null ? "null" : item.toString()); setGraphic(null); } } }; }
