Invalidate Method (AnnEditDesigner)

public override void Invalidate( 
   LeadRectD rc
)

Public Overrides Sub Invalidate( _
   ByVal rc As LeadRectD _
) 

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 Leadtools.Annotations.Core.IAnnAutomationControl.AutomationInvalidate(Leadtools.LeadRectD) method.
