Detailed Description
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.
See also QAccessible and QAccessibleBridgePlugin.

void QAccessibleBridge::notifyAccessibilityUpdate ( int reason, QAccessibleInterface * interface, int child ) [pure virtual]
