Constructor Detail

AccessibleJRootPane

protected AccessibleJRootPane()

方法详细信息

getAccessibleRole

public AccessibleRole getAccessibleRole()

获取此对象的角色。

重写：

getAccessibleRole 方法重写，继承类 JComponent.AccessibleJComponent

结果

accessiblerole描述的作用的对象的一个实例

另请参见：

AccessibleRole

getAccessibleChildrenCount

public int getAccessibleChildrenCount()

返回对象的可访问的子对象的数目。

重写：

getAccessibleChildrenCount 方法重写，继承类 JComponent.AccessibleJComponent

结果

对象的可访问的儿童的数量。

getAccessibleChild

public Accessible getAccessibleChild(int i)

返回指定的对象的可访问子对象。可访问的对象的可访问的儿童是零的，所以一个可访问的孩子的第一个孩子是在指数0，第二个孩子是在指数1，等等。

重写：

getAccessibleChild 方法重写，继承类 JComponent.AccessibleJComponent

参数

i -零基础指数的孩子

结果

对象的可访问的子对象

另请参见：

getAccessibleChildrenCount()
