详细描述

The QAccessibleBridgePlugin class provides an abstract base for accessibility bridge plugins.

Writing an accessibility bridge 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。

成员函数文档编制

QAccessibleBridgePlugin:: QAccessibleBridgePlugin ( QObject * parent = 0)

Constructs an accessibility bridge plugin with the given parent . This is invoked automatically by the Q_EXPORT_PLUGIN2 () 宏。

QAccessibleBridgePlugin:: ~QAccessibleBridgePlugin ()

Destroys the accessibility bridge plugin.

从不需要明确调用这。Qt 自动销毁插件当不再使用时。

`[pure virtual]` QAccessibleBridge * QAccessibleBridgePlugin:: create (const QString & key )

Creates and returns the QAccessibleBridge object corresponding to the given key 。键区分大小写。

另请参阅 keys ().

`[pure virtual]` QStringList QAccessibleBridgePlugin:: keys () const

Returns the list of keys this plugins supports.

These keys must be the names of the bridges that this plugin provides.

另请参阅 create ().
