Invalidate Method (AnnDesigner)
Summary
Manually invalidates this designer.
Syntax
public virtual void Invalidate(Leadtools.LeadRectD rc)
Public Overridable Sub Invalidate( _ByVal rc As Leadtools.LeadRectD _)
public virtual void Invalidate(Leadtools.LeadRectD rc)
- (void)invalidate:(LeadRectD)rectpublic 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.
Remarks
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.
