Thanks, Markus.  Since I describe myself as novice to some of this 
technical jargon you probably think I'm not clear with what I'm looking 
for.  But I actually am.  The example that I posted is very consistent 
with the namesake of this thread.  I'm hoping to have the minimum number 
of lines to update a gui window without the user having to do anything 
but just periodically look at the screen and notice the updates.

Now since I appear to have the minimum (in my example), which performs 
perfectly.  If you analyze it, I believe it'll become clearer what my 
question is about.

Having the minimum lines will help me to study in more detail and 
understand better what is taking place.

Do you see any technical problems with what I posted?  Do you think you 
could make it more efficient?  I'm sure, with time, I'll be able to.

One of the things I would like to do is turn this lines into one line:

// Code Begin
// ----------------------------------------------
    texttoprint += "Back from running a short 10 second function";
    m_refTextBuffer->set_text(texttoprint);
    m_textview.set_buffer(m_refTextBuffer);
// ----------------------------------------------
// Code end

Of course I expect this will take a significantly lots more programming 
lines to make such a class or function.  But in the end it'll make using 
gtk a lot easier for many applications.

I hope to create a class or function that could be called and would 
either append or replace the text being displayed.  The function could 
be called, "gprint()".  Then, instead of writing three lines to update 
the gui window, I'd be able to type:

gprint("Updated text");

And have the text updated that way.

Thanks again for your input and your attempts to understand my question.

Again, I believe the current question is answered with the last code I 
posted, unless you see a problem with it.  After I have a good clean 
example of my attempt to create the "gprint()" class or function, I'll 
post that and ask for help.
