构造方法详细信息

SynthTreeUI

public SynthTreeUI()

方法详细信息

createUI

public static ComponentUI createUI(JComponent x)

为给定的组件创建一个新的UI对象。

参数

x - 为其创建UI对象的组件

结果

UI对象

getExpandedIcon

public Icon getExpandedIcon()

重写：

getContext

public SynthContext getContext(JComponent c)

返回指定组件的上下文。

Specified by:

getContext在界面 SynthUI

参数

c - 组件请求SynthContext。

结果

SynthContext描述组件。

createDefaultCellEditor

protected TreeCellEditor createDefaultCellEditor()
