After you insert the string, use XmTextGetLastPosition to figure the last 
position of your text widget, and then use XmTextShowPosition to make
the last line of the added text visible.

The prototypes of the above two calls are:

XmTextPosition XmTextGetLastPosition(Widget);
void           XmTextSetTopCharacter(Widget, XmTextPosition);

Hope it helps.
