信息技术.辅助技术(AT)的互操作性.第3部分:IAccessible2可访问性应用程序接口(API)

[中文适用范围]： ISO/IEC 13066-3 提供了 IAccessible2 无障碍 API 的结构和术语概览。它提供了：API 的整体架构和术语描述；关于 API 内容和使用情况的进一步 introductory 说明（超出 ISO/IEC 13066-1 附录 A 的内容）；主要属性概述，包括用户界面元素、获取和设置焦点的方法、API 中的通信机制；对 API 设计考虑的讨论（例如，指向有关使用 API 的无障碍指南的外部信息来源）；关于扩展 API 的信息（以及在何处扩展）；API 编程接口的介绍（包括指向外部信息来源的指针）。它提供这些信息作为 IAccessible2 API 的介绍，以协助：创建自定义控件和/或其接口的 IT 系统级开发人员；参与“硬件到软件”和“软件到软件”交互编程的 AT 开发人员。 [外文原描述]： ISO/IEC TR 13066:2012 provides an overview to the structure and terminology of the IAccessible2 accessibility API. It provides: a description of the overall architecture and terminology of the API; further introductory explanations regarding the content and use of the API beyond those found in Annex A of ISO/IEC 13066-1; an overview of the main properties, including: of user interface elements, of how to get and set focus, of communication mechanisms in the API; a discussion of design considerations for the API (e.g. pointers to external sources of information on accessibility guidance related to using the API); information on extending the API (and where this is appropriate); an introduction to the programming interface of the API (including pointers to external sources of information). It provides this information as an introduction to the IAccessible2 API to assist: IT system level developers who create custom controls and/or interface to them; AT developers involved in programming "hardware to software" and "software to software" interactions.
