构造方法详细信息

MetalSliderUI

public MetalSliderUI()

方法详细信息

createUI

public static ComponentUI createUI(JComponent c)

installUI

public void installUI(JComponent c)

从类 ComponentUI 复制的描述

配置指定组件，使其适合外观。当 ComponentUI 实例将作为 UI 委托安装在指定组件上时，可调用此方法。此方法应该为外观完整地配置组件，包括以下方面：

在组件上安装用于颜色、字体、边框、图标、不透明性等方面的所有默认属性值。只要有可能，就不应该重写由客户端程序初始化的属性值。
如有必要，可在组件上安装一个 LayoutManager。
将所需的所有子组件创建/添加到组件中。
在组件上创建/安装事件侦听器。
为了检测和适当响应组件属性更改，可在组件上创建/安装一个 PropertyChangeListener。
在组件上安装键盘 UI（助记符、遍历等等）。
初始化任何适当的实例数据。

参数：: c - 将安装此 UI 委托的组件

覆盖：: 类 BasicSliderUI 中的 getTickLength

getTrackWidth

protected int getTrackWidth()

返回较短的滑道尺寸。

getTrackLength
