invalidate Method (AnnEditDesigner)

Summary

Manually invalidates this designer.

Syntax

JavaScript Syntax
AnnEditDesigner.prototype.invalidate = function(rc)
TypeScript Syntax
invalidate(rc: LeadRectD): void;

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 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.
