public abstract class QAccessibleBridge
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.

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 arg__2.
arg__1 specifies the cause of the change. It can take values of type QAccessible::Event.
arg__3 is the (1-based) index of the child element that has changed. When arg__3 is 0, the object itself has changed.
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 arg__1. All other accessible objects in the application can be reached by the client using object navigation.
public static QAccessibleBridge fromNativePointer(QNativePointer nativePointer)
nativePointer
- the QNativePointer of which object should be returned.
