```
public class MetalTreeUI
extends BasicTreeUI
```
金属外观实现TreeUI 。
MetalTreeUI允许配置如何在视觉上呈现节点之间的间距和描绘。支持以下提示：
Descriptions of supported hints: Angled, Horizontal, and None Hint Description Angled A line is drawn connecting the child to the parent. For handling of the root node refer to JTree.setRootVisible(boolean) and JTree.setShowsRootHandles(boolean). Horizontal A horizontal line is drawn dividing the children of the root node. None Do not draw any visual indication between nodes.

由于它一般是不切实际获得TreeUI从JTree并浇铸成的实例MetalTreeUI启用通过客户端属性这个属性JTree.lineStyle 。例如，要切换到Horizontal样式，您可以执行以下操作： tree.putClientProperty("JTree.lineStyle", "Horizontal");

默认值为Angled 。
