I am interested in extending the functionality of the Text Widget by
providing my own source of data.  I understand that this is how
the AsciiStringWidget and AsciiDiskWidget are derived from the
textWidgetClass.  I also understand about XtStringSourceCreate
(and its friends).  I assume that a "source" provides data upon
demand to the text widget.  I also assume that this happens when
the text widget makes one or more calls requesting the data.  What
I do not understand and have not been able to find documented are
the interfaces that these functions have.  I would appreciate
be pointed at any available documents or examples that make use
of this ability.  I would also appreciate hearing recommendation
of when it is appropriate or inappropriate to use this facility.

Thanks.
