Invalidate Method (AnnDesigner)

public virtual void Invalidate( 
   LeadRectD rc
)

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

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