The QAccessiblePlugin class provides an abstract base for accessibility plugins.
Writing an accessibility plugin is achieved by subclassing this base class, reimplementing the pure virtual functions keys () 和 create (),和导出类采用 Q_EXPORT_PLUGIN2 () 宏。
另请参阅 QAccessibleBridgePlugin and 如何创建 Qt 插件 .
构造可访问性插件采用给定 parent . This is invoked automatically by the Q_EXPORT_PLUGIN2 () 宏。
销毁可访问性插件。
从不需要明确调用这。Qt 自动销毁插件当不再使用时。
[pure virtual]
QAccessibleInterface
* QAccessiblePlugin::
create
(const
QString
&
key
,
QObject
*
object
)
创建并返回 QAccessibleInterface 实现为类 key 和对象 object 。键区分大小写。

[pure virtual]
QStringList
QAccessiblePlugin::
keys
() const
Returns the list of keys this plugin supports.
These keys must be the class names that this plugin provides an accessibility implementation for.
