Detailed Description
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.

Member Function Documentation
QAccessiblePlugin::QAccessiblePlugin(QObject *parent = nullptr)
Constructs an accessibility plugin with the given parent. This is invoked automatically by the plugin loader.
[virtual] 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.
