Object.defineProperty(AnnAutomation.prototype,'editText',
get: function(),

editText: LeadEvent;
This event will occur when the object being edited is a text object and the user initiates edit mode. For more information, refer to AnnTextEditDesigner.EditText.
If the value of EditTextAfterDraw is set to true, this event will occur automatically after the designer finishes drawing new text objects.
The following example will show how to change the string used by an annotation text object when it enters edit mode.
