继承者说明

如果对象包装系统控件, 则默认实现将返回可访问对象的说明;否则, 它将null返回。The default implementation returns the accessible object's description if the object wraps a system control; otherwise, it returns null. 描述通常用于为弱视用户或盲人用户提供更大的上下文。The description is typically used to provide greater context for low-vision or blind users. 它还可以用于上下文搜索或其他应用程序。It can also be used for context searching or other applications. 如果说明不明显, Description或基于对象的NameRoleStateValue属性, 则服务器需要支持属性。Servers need to support the Description property if the description is not obvious, or if it is redundant based on the object's Name, Role, State, and Value properties. 例如, 具有 "确定" 的按钮不需要其他信息, 但显示仙人掌图片的按钮会。For example, a button with "OK" does not need additional information, but a button that shows a picture of a cactus would. 仙人掌按钮RoleName"、 Help " 和 "可能" 属性说明了其用途, 但属性传达的信息不太明确,如"按钮显示仙人掌类照片"。DescriptionThe Name, Role, and perhaps Help properties for the cactus button describe its purpose, but the Description property conveys information that is less tangible, like "A button that shows a picture of a cactus".
