Oh, oh. I just re-read your post. Sounds like you
might have a multi-line text widget, and I stole the
example above from a single-line text widget. You will
have to modify the code to cope with whatever you have,
but you get the idea.
Cheers,
David

Try something like this, after you have put the new
text into the text widget:
Widget_Control, textID, Get_Value=theText
theText = theText[0]
Widget_Control, textID, Set_Text_Select=[StrLen(theText)-1]
