绑定TreeTableView

Question

如何绑定TreeTableView？这给了我一个错误：

tblTreeView.rootProperty().bind(model.transactionProperty());

where transactionProperty()

public SimpleListProperty<Document> transactionsProperty() {
        if(transactions == null){
            transactions = new SimpleListProperty<>();
        }
        return transactions;
    }

Answer 1

TreeTableView<Document> treeTable = new TreeTableView<>();
ObjectProperty<TreeItem<Document>> rootProperty = treeTable.rootProperty();

它可以绑定到ObservableValue<TreeItem<S>>

ObjectProperty<TreeItem<Document>> modelProperty = new SimpleObjectProperty<>();
rootProperty.bind(modelProperty);

modelProperty.set(myDocument); // will update the bound root property
