All Implemented Interfaces:

Serializable ， AccessibleComponent ， AccessibleExtendedComponent

Enclosing class:

JRootPane

protected class JRootPane.AccessibleJRootPane
extends JComponent.AccessibleJComponent

该类实现对JRootPane类的辅助功能支持。 它提供了适用于根窗格用户界面元素的Java Accessibility API的实现。

警告：此类的序列化对象与将来的Swing版本不兼容。 当前的序列化支持适用于运行相同版本的Swing的应用程序之间的短期存储或RMI。 从1.4开始，对所有JavaBeans的长期存储的支持已经添加到java.beans包中。 请参阅XMLEncoder 。

构造方法详细信息

AccessibleJRootPane

protected AccessibleJRootPane()

方法详细信息

getAccessibleRole

public AccessibleRole getAccessibleRole()

获取此对象的角色。

重写：

getAccessibleRole中的 JComponent.AccessibleJComponent

结果

AccessibleRole的一个实例描述对象的角色

另请参见：

AccessibleRole

getAccessibleChildrenCount

public int getAccessibleChildrenCount()

返回对象的可访问子对象的数量。

重写：

getAccessibleChildrenCount在 JComponent.AccessibleJComponent类

结果

对象的可访问子的数量。

getAccessibleChild

public Accessible getAccessibleChild(int i)

返回对象的指定Accessible子对象。 Accessible对象的Accessible子项为零，因此Accessible子项的第一个子项的索引为0，第二个子项为索引1，依此类推。

重写：

getAccessibleChild在 JComponent.AccessibleJComponent

参数

i - 基于零的儿童索引

结果

对象的Accessible子对象

另请参见：

getAccessibleChildrenCount()
