详细描述
The QAccessiblePlugin class provides an abstract base class for plugins provinding accessibility information for user interface elements.
Writing an accessibility plugin is achieved by subclassing this base class, reimplementing the pure virtual function create(), and exporting the class with the Q_PLUGIN_METADATA() macro.
成员函数
QAccessiblePlugin::QAccessiblePlugin(QObject *parent = Q_NULLPTR)
Constructs an accessibility plugin with the given parent. This is invoked automatically by the plugin loader.
QAccessiblePlugin::~QAccessiblePlugin()
Destroys the accessibility plugin.
You never have to call this explicitly. Qt destroys a plugin automatically when it is no longer used.
[pure virtual] QAccessibleInterface *QAccessiblePlugin::create(const QString &key, QObject *object)
Creates and returns a QAccessibleInterface implementation for the class key and the object object. Keys are case sensitive.
