Similar to the display manager and the input delegate, keep the accessibility delegate under the base class. Also, following the same pattern as in the parent patch, assign a default instance for this in the delegate in the constructor, and initialize anything later when needed. Also, make sure calls for various objects under the QtAccessibilityDelegate are safe and guarded.
