本文整理了Java中org.eclipse.swt.accessibility.Accessible类的一些代码示例，展示了Accessible类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Accessible类的具体详情如下：
包路径：org.eclipse.swt.accessibility.Accessible
类名称：Accessible

Accessible介绍

[英]Instances of this class provide a bridge between application code and assistive technology clients. Many platforms provide default accessible behavior for most widgets, and this class allows that default behavior to be overridden. Applications can get the default Accessible object for a control by sending it getAccessible, and then add an accessible listener to override simple items like the name and help string, or they can add an accessible control listener to override complex items. As a rule of thumb, an application would only want to use the accessible control listener to implement accessibility for a custom control.
[中]此类实例提供了应用程序代码和辅助技术客户端之间的桥梁。许多平台为大多数小部件提供默认的可访问行为，这个类允许覆盖默认行为。应用程序可以通过发送控件getAccessible来获取该控件的默认可访问对象，然后添加一个可访问的侦听器以覆盖简单项，如名称和帮助字符串，或者可以添加一个可访问的控件侦听器以覆盖复杂项。根据经验，应用程序只希望使用可访问控件侦听器实现自定义控件的可访问性。
