1.TreeView实现效果

TreeView实现效果如下图所示，每个结点包含图片并且右击节点可以显示菜单项

javafx首页 javafx菜单_eclipse

2.菜单类

菜单类负责在右击节点时显示菜单，具体是是实现如下所示，为了节省代码占用行数，省略了一些代码

private final class TextFieldTreeCellImpl extends TreeCell<String> {

        private TextField textField;// 文本域外观组件对象
        // 上下文菜单对象的创建
        private final ContextMenu addMenu1 = new ContextMenu();
        private final ContextMenu addMenu2 = new ContextMenu();
        private final ContextMenu addMenu3 = new ContextMenu();
        private final ContextMenu addMenu4 = new ContextMenu();
        private final ContextMenu addMenu5 = new ContextMenu();

        public TextFieldTreeCellImpl() {// 构造方法的定义
            // 上下文菜单选项对象的创建
            MenuItem addMenuItem1 = new MenuItem("添加小区节点");
            MenuItem addMenuItem2 = new MenuItem("添加楼号节点");
            MenuItem addMenuItem3 = new MenuItem("添加单元节点");
            MenuItem addMenuItem4 = new MenuItem("添加房间节点");
            MenuItem removeMeunItem1 = new MenuItem("删除小区节点");
            MenuItem removeMeunItem2 = new MenuItem("删除楼号节点");
            MenuItem removeMeunItem3 = new MenuItem("删除单元节点");
            MenuItem removeMeunItem4 = new MenuItem("删除房间节点");
            MenuItem maintain = new MenuItem("维护房间节点");
            //将上下文菜单选项对象添加至上下文菜单对象                                
            addMenu1.getItems().add(addMenuItem1);
            addMenu2.getItems().add(addMenuItem2);
            addMenu3.getItems().add(addMenuItem3);
            addMenu4.getItems().add(addMenuItem4);
            addMenu2.getItems().add(removeMeunItem1);
            addMenu3.getItems().add(removeMeunItem2);
            addMenu4.getItems().add(removeMeunItem3);
            addMenu5.getItems().add(removeMeunItem4);
            addMenu5.getItems().add(maintain);

            //点击上下文菜单选项触发的事件如下
            addMenuItem1.setOnAction((ActionEvent t) -> {
                //以下代码段表示事件触发所执行的代码
                index = 1;
                PopWindow(getTreeItem());
            });// 添加小区节点
        }

        // 获取该Item的名字
        private String getString() {
            return getItem() == null ? "" : getItem().toString();
        }
        //以下代码负责判断右击节点显示哪个菜单
        public void updateItem(String item, boolean empty) {
            super.updateItem(item, empty);

            if (empty) {
                setText(null);
                setGraphic(null);
            } else {
                setText(getString());
                setGraphic(getTreeItem().getGraphic());
                if (getTreeItem().getParent() == null) {
                    setContextMenu(addMenu1);
                } else if (getTreeItem().getParent().getParent() == null) {
                    setContextMenu(addMenu2);
                } else if (getTreeItem().getParent().getParent().getParent() == null) {
                    setContextMenu(addMenu3);
                } else if (getTreeItem().getParent().getParent().getParent().getParent() == null) {
                    setContextMenu(addMenu4);
                } else if (getTreeItem().isLeaf()) {
                    setContextMenu(addMenu5);
                } else
                    setContextMenu(null);
            }

        }
    }

}

3.TreeView显示

图片格式要求
像素，位置跟Controller类最好在同一个包，不然不好调用图片。

javafx首页 javafx菜单_Powered by 金山文档_03

定义根节点图片

private final Node rootIcon = new ImageView(new Image(getClass().getResourceAsStream("12345.png")));

定义分支节点图片

private final Image depIcon1 = new Image(getClass().getResourceAsStream("11.png"));

定义根节点属性

rootItem = new TreeItem<String>("房屋管理", rootIcon);

定义分支节点属性

TreeItem<String> item1 = new TreeItem<>(area.getAreaName(), new ImageView(depIcon1));

完整代码如下所示，值得注意的是最好不要在scenebuilder中建立TreeView，而是在scenebuilder中建立VBox，再将TreeView添加置VBox中去

private final Node rootIcon = new ImageView(new Image(getClass().getResourceAsStream("12345.png")));
    // 创建图片节点
    private final Image depIcon1 = new Image(getClass().getResourceAsStream("11.png"));
    private final Image depIcon2 = new Image(getClass().getResourceAsStream("22.png"));
    private final Image depIcon3 = new Image(getClass().getResourceAsStream("31.png"));
    private final Image depIcon4 = new Image(getClass().getResourceAsStream("41.png"));

    @Override
    public void initialize(URL arg0, ResourceBundle arg1) {
        HouseCatalog.getHouseCatalog().loadJson();
        rootItem = new TreeItem<String>("房屋管理", rootIcon);
        areas = HouseCatalog.getHouseCatalog().getAreas();
        for (Area area : areas) {
            TreeItem<String> item1 = new TreeItem<>(area.getAreaName(), new ImageView(depIcon1));
            rootItem.getChildren().add(item1);
            for (Building building : area.getBuildings()) {
                TreeItem<String> item2 = new TreeItem<>(building.getBuildingName(), new ImageView(depIcon2));
                item1.getChildren().add(item2);
                for (Unit unit : building.getUnits()) {
                    TreeItem<String> item3 = new TreeItem<String>(unit.getUnitname(), new ImageView(depIcon3));
                    item2.getChildren().add(item3);
                    for (House house : unit.getHouses()) {
                        TreeItem<String> item4 = new TreeItem<String>(house.getHouseName(), new ImageView(depIcon4));
                        item3.getChildren().add(item4);
                    }
                }
            }
        }
        TreeView<String> treeView = new TreeView<String>(rootItem);// 创建一个树形结构根节点
        treeView.setCellFactory((TreeView<String> p) -> new TextFieldTreeCellImpl());//设立菜单
        vBox.getChildren().add(treeView);//在vBox中添加TreeView
    }
