) 

'Usage
 

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

public override void Invalidate( 
   LeadRectD rc
)

- (void)invalidate:(LeadRectD)rect

@Override public void invalidate(LeadRectD rc)

 function Leadtools.Annotations.Designers.AnnEditDesigner.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 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.
