Class JRootPane.AccessibleJRootPane

java.lang.Object

javax.accessibility.AccessibleContext

java.awt.Component.AccessibleAWTComponent

java.awt.Container.AccessibleAWTContainer

javax.swing.JComponent.AccessibleJComponent

javax.swing.JRootPane.AccessibleJRootPane

所有已实现的接口:

Serializable, AccessibleComponent, AccessibleExtendedComponent

封装类:

JRootPane

       protected class JRootPane.AccessibleJRootPane extends JComponent.AccessibleJComponent
      

该类实现了对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辅助功能API的实现。

警告: 该类的序列化对象将不兼容未来的Swing版本。当前的序列化支持适用于短期存储或在运行相同Swing版本的应用程序之间的RMI。从1.4版本开始，已将所有JavaBeans的长期存储支持添加到java.beans包中。请参阅XMLEncoder。

Constructor Details

AccessibleJRootPane

             protected AccessibleJRootPane()
            

构造一个AccessibleJRootPane。

Method Details

getAccessibleRole

             public AccessibleRole getAccessibleRole()
            

获取此对象的角色。

覆盖:

getAccessibleRole 在类 JComponent.AccessibleJComponent

返回:

描述对象角色的AccessibleRole实例

参见:

• AccessibleRole

getAccessibleChildrenCount

             public int getAccessibleChildrenCount()
            

返回对象的可访问子项数量。

覆盖:

getAccessibleChildrenCount 在类 JComponent.AccessibleJComponent

返回:

对象的可访问子项数量。

getAccessibleChild

             public Accessible getAccessibleChild(int i)
            

返回对象的指定可访问子项。Accessible对象的Accessible子项是从零开始的，因此Accessible子项的第一个子项位于索引0，第二个子项位于索引1，依此类推。

覆盖:

getAccessibleChild 在类 JComponent.AccessibleJComponent

参数:

i - 子项的从零开始的索引

返回:

对象的Accessible子项

参见:

• getAccessibleChildrenCount()
