Comments

This structure is used with the WM_LTANNEVENT message LTANNEVENT_HIGHLIGHT in the lParam argument. This message is used when selecting the object (except for the rotated ellipse, protractor, ruler, and cross product objects), changing the object using automation, or changing the object by making calls to L_AnnDefine. The message is also useful for updating information about an annotation in real time.
