'Declaration

   ByVal rc As LeadRectD _
) 

'Usage
 

Dim instance As AnnDesigner
Dim rc As LeadRectD
 
instance.Invalidate(rc)

public virtual void Invalidate( 
   LeadRectD rc
)

- (void)invalidate:(LeadRectD)rect

public void invalidate(LeadRectD rc)

 function Leadtools.Annotations.Designers.AnnDesigner.Invalidate( 
   rc 
)

Parameters

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 will call the Invalidate method to do that. In turn, the Invalidate method determines if there is a valid object in the AutomationControl and calls its AutomationInvalidate method.
