@Override public void invalidate(LeadRectD rc)
The region to invalidate. If the value of this parameter is LeadRectD.Empty, then the entire surface is invalidated.
If the various derived designers determine that the surface of the container needs repainting they call the Invalidate method to perform the repaint. In turn, the Invalidate determines whether there is a valid object in the AutomationControl and calls its AutomationInvalidate method.
