Sets \a iface to point to the implementation of the

successfull, or sets \a iface to 0 and returns \c QE_NOCOMPONENT if
no accessibility implementation for \a object exists.
The function uses the \link QObject::className() classname
\endlink of \a object to find a suitable implementation. If no
implementation for the object's class is available the function
tries to find an implementation for the object's parent class.
This function is called to answer an accessibility client's
request for object information. You should never need to call this
function yourself.
