invalidateObject Method

Summary

Invalidates and re-draws an object.

Syntax

TypeScript

JavaScript

AnnAutomation.prototype.invalidateObject = function( 
   annObject 
)

invalidateObject( 
   annObject: AnnObject 
): void;

Parameters

annObject

The object to re-draw. A value of null will be ignored.

Remarks

Use GetObjectInvalidateRect to obtain the current physical rectangle of the object. This method will call AnnObject.GetInvalidateRect and then adds the rectangles of any thumbs (if the object is selected) into the result value.

You can call IAnnAutomationControl.AutomationInvalidate on the value returned from this function to re-draw the object. Or you can call InvalidateObject which performs this automatically.
