49 \class QAccessibleBridge
50 \brief The QAccessibleBridge class is the base class for
51 accessibility back-ends.
54 \ingroup accessibility
57 Qt supports Microsoft Active Accessibility (MSAA), Mac OS X
58 Accessibility, and the Unix/X11 AT-SPI standard. By subclassing
59 QAccessibleBridge, you can support other backends than the
62 Currently, custom bridges are only supported on Unix. We might
63 add support for them on other platforms as well if there is
66 \sa QAccessible, QAccessibleBridgePlugin
70 \fn QAccessibleBridge::~QAccessibleBridge()
72 Destroys the accessibility bridge object.
76 \fn void QAccessibleBridge::setRootObject(QAccessibleInterface *object)
78 This function is called by Qt at application startup to set the
79 root accessible object of the application to \a object. All other
80 accessible objects in the application can be reached by the
81 client using object navigation.
85 \fn void QAccessibleBridge::notifyAccessibilityUpdate(QAccessibleEvent *event)
87 This function is called by Qt to notify the bridge about a change
88 in the accessibility information. The \a event specifies the interface,
89 object, reason and child element that has changed.
91 \sa QAccessible::updateAccessibility()
95 \class QAccessibleBridgePlugin
96 \brief The QAccessibleBridgePlugin class provides an abstract
97 base for accessibility bridge plugins.
101 \ingroup accessibility
104 Writing an accessibility bridge plugin is achieved by subclassing
105 this base class, reimplementing the pure virtual function create(),
106 and exporting the class with the Q_PLUGIN_METADATA() macro.
108 \sa QAccessibleBridge, QAccessiblePlugin, {How to Create Qt Plugins}
112 Constructs an accessibility bridge plugin with the given \a
113 parent. This is invoked automatically by the plugin loader.
115 QAccessibleBridgePlugin::QAccessibleBridgePlugin(QObject *parent)
122 Destroys the accessibility bridge plugin.
124 You never have to call this explicitly. Qt destroys a plugin
125 automatically when it is no longer used.
127 QAccessibleBridgePlugin::~QAccessibleBridgePlugin()
133 \fn QAccessibleBridge *QAccessibleBridgePlugin::create(const QString &key)
135 Creates and returns the QAccessibleBridge object corresponding to
136 the given \a key. Keys are case sensitive.
