## com.trolltech.qt.gui
Class QAccessibleBridge

    java.lang.Object
      com.trolltech.qt.internal.QSignalEmitterInternal
          com.trolltech.qt.QSignalEmitter
              com.trolltech.qt.QtJambiObject
                  com.trolltech.qt.gui.QAccessibleBridge

All Implemented Interfaces:
  QtJambiInterface

    public abstract class QAccessibleBridge

extends QtJambiObject

The `QAccessibleBridge` class is the base class for accessibility back-ends. Qt supports Microsoft Active Accessibility (MSAA), Mac OS X Accessibility, and the Unix/X11 AT-SPI standard. By subclassing `QAccessibleBridge`, you can support other backends than the predefined ones.

Currently, custom bridges are only supported on Unix. We might add support for them on other platforms as well if there is enough demand.

  `QAccessible`, and QAccessibleBridgePlugin.

Method Detail

### notifyAccessibilityUpdate

    public abstract void notifyAccessibilityUpdate(int arg__1,
                                                   QAccessibleInterface arg__2,
                                                   int arg__3)

  This function is called by Qt to notify the bridge about a change in the accessibility information for object wrapped by the given `interface`.

  `reason` specifies the cause of the change. It can take values of type `QAccessible::Event` .

  `child` is the (1-based) index of the child element that has changed. When `child` is 0, the object itself has changed.

See also:
  `QAccessible::updateAccessibility()`.

### setRootObject

    public abstract void setRootObject(QAccessibleInterface arg__1)

  This function is called by Qt at application startup to set the root accessible object of the application to `object`. All other accessible objects in the application can be reached by the client using object navigation.
