Sets the cell factory that will be used for creating TreeCells, which are used to represent items in the TreeView.

Usage

From source file:Main.java

@Override
public void start(Stage primaryStage) {
    CheckBoxTreeItem<String> rootItem = new CheckBoxTreeItem<>("A");
    rootItem.setExpanded(true);//  w ww  . jav  a2s.co m

    TreeView tree = new TreeView(rootItem);
    tree.setEditable(true);

    tree.setCellFactory(CheckBoxTreeCell.forTreeView());

    CheckBoxTreeItem<String> checkBoxTreeItem = new CheckBoxTreeItem<>("a");
    rootItem.getChildren().add(checkBoxTreeItem);

    checkBoxTreeItem = new CheckBoxTreeItem<>("b");
    rootItem.getChildren().add(checkBoxTreeItem);

    tree.setRoot(rootItem);

    StackPane root = new StackPane();
    root.getChildren().add(tree);
    primaryStage.setScene(new Scene(root, 300, 250));
    primaryStage.show();
