javax.swing.plaf.metal.MetalTreeUI

public class MetalTreeUI
extends BasicTreeUI

金属质感的实施 TreeUI。

MetalTreeUI允许配置如何可视化渲染节点之间的间距和划分。支持以下提示：

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.

它通常是从JTree抛到MetalTreeUI启用此属性通过客户财产JTree.lineStyle实例获得TreeUI不切实际。例如，切换到Horizontal风格你会做的事：tree.putClientProperty("JTree.lineStyle", "Horizontal");

默认的是Angled。

方法详细信息

createUI

public static ComponentUI createUI(JComponent x)

getHorizontalLegBuffer

protected int getHorizontalLegBuffer()

从阶级复制的描述： BasicTreeUI

节点之间的腿的水平元素在默认情况下，在子节点的左侧右侧开始。这种方法使腿结束之前。

重写：

getHorizontalLegBuffer 方法重写，继承类 BasicTreeUI

installUI

public void installUI(JComponent c)

从阶级复制的描述： ComponentUI

配置指定的组件适当的外观和感觉。这个方法被调用时， ComponentUI实例被安装在指定组件的UI代理。这种方法应该完全配置的组件外观和感觉，包括以下内容：

1. 在组件上安装颜色、字体、边框、图标、不透明度等的默认属性值。只要有可能，属性值由客户端程序初始化应该不被重写。
2. 安装一个LayoutManager组件上的必要。
3. 创建/添加任何所需的子组件到组件。
4. 在组件上创建/安装事件侦听器。
5. 创建/安装为组件的检测和响应组件的属性PropertyChangeListener变化适当。
6. 安装键盘UI（助记符，遍历等）的成分。
7. 初始化任何适当的实例数据。

重写：

installUI 方法重写，继承类 BasicTreeUI

参数

c -组件，UI代理被安装

另请参见：

ComponentUI.uninstallUI(javax.swing.JComponent)， JComponent.setUI(javax.swing.plaf.ComponentUI)， JComponent.updateUI()

uninstallUI

public void uninstallUI(JComponent c)

从阶级复制的描述： ComponentUI

逆转形态，完成指定的组件在 installUI。这个方法被调用时，这个 UIComponent实例被作为指定组件的UI代理删除。这种方法应该撤消配置进行 installUI，小心留下的 JComponent实例在干净的状态（没有多余的听众，外观和感觉的特定属性的对象，等）。这应包括以下几个方面：

1. 从组件中删除任何用户界面设置的边框。
2. 删除组件上的任何用户界面设置的布局管理器。
3. 从组件中删除任何添加的子组件的用户界面。
4. 从组件中删除任何添加事件/属性侦听器的用户界面。
5. 从组件中删除任何安装键盘用户界面的用户界面。
6. 取消任何分配的实例数据对象允许GC。

重写：

uninstallUI 方法重写，继承类 BasicTreeUI

参数

c -从这个UI代理被删除的组件；这种说法常常被忽视，但可能如果UI对象是无状态的，共享由多个组件

另请参见：

ComponentUI.installUI(javax.swing.JComponent)， JComponent.updateUI()

paint

public void paint(Graphics g,
                  JComponent c)

从阶级复制的描述： ComponentUI

适当地绘制指定的组件的外观和感觉。这种方法是从 ComponentUI.update方法调用时指定的组件正在粉刷。子类应重写此方法，并使用指定的 Graphics对象呈现的成分含量。

重写：

paint 方法重写，继承类 BasicTreeUI

参数

g - Graphics背景的画

c -正在绘制的构件；这种说法常常被忽视，但可能如果UI对象是无状态的，共享由多个组件
