• 组织一组tab的容器，可以设置关闭，拖拽等
• 每个tab内容可以设置不同容器数据

常用属性

padding

内边距，可以单独设置上、下、左、右的内边距

tabPane.setPadding(new Insets(10, 10, 10, 10));

side

设置tabs的位置,LEFT

tabPane.setSide(Side.LEFT);

public enum Side {
    TOP,
    BOTTOM,
    LEFT,
    RIGHT;
}

tabClosingPolicy

tab关闭策略

tabPane.setTabClosingPolicy(TabPane.TabClosingPolicy.UNAVAILABLE);

public enum TabClosingPolicy {
        /**
         * 仅仅当前选中的tab可以关闭
         */
        SELECTED_TAB,

        /**
         * 所有tab都可关闭
         */
        ALL_TABS,

        /**
         * 所有tab都不可关闭.
         */
        UNAVAILABLE
    }

tabDragPolicy

拖拽策略

tabPane.setTabDragPolicy(TabPane.TabDragPolicy.FIXED);

public enum TabDragPolicy {
        /**
         * 固定不允许拖拽
         */
        FIXED,

        /**
         * 允许拖拽
         */
        REORDER
    }

实现方式

Java实现

 public static TabPane demo1() {
        TabPane tabPane = new TabPane();
        // 内边距
        tabPane.setPadding(new Insets(10, 10, 10, 10));
        // 位置
        tabPane.setSide(Side.LEFT);
        // 关闭策略
        tabPane.setTabClosingPolicy(TabPane.TabClosingPolicy.UNAVAILABLE);
        // 拖拽策略
        tabPane.setTabDragPolicy(TabPane.TabDragPolicy.FIXED);
        tabPane.setRotateGraphic(false);
        tabPane.setCenterShape(false);

        Tab tab1 = new Tab("Tab 1");
        FlowPane flowPane1 = new FlowPane();
        flowPane1.setOrientation(Orientation.HORIZONTAL);
        for (int i = 1; i <= 5; i++) {
            flowPane1.getChildren().add(new Button("Button " + i));
        }
        tab1.setContent(flowPane1);

        Tab tab2 = new Tab("Tab 2");
        FlowPane flowPane2 = new FlowPane();
        flowPane2.setOrientation(Orientation.VERTICAL);
        for (int i = 6; i <= 10; i++) {
            flowPane2.getChildren().add(new Button("Button " + i));
        }
        tab2.setContent(flowPane2);

        tabPane.getTabs().addAll(tab1, tab2);

        return tabPane;
    }
