I don't know what you mean by design extensions.  But I started out 
programming in assmebly language in the Late 70's.  I went to C in the 
early 80's.  It was all in DOS, not Windows.  In the late 90's I started 
using a "semi" graphical interface by programming perl CGI. I also 
started using Visual C++ and the MFC environment around that time.

Maybe it's the MFC that you're referring to in "playing" around with 
software design extensions.  For MFC in Visual Studio you basically just 
draw a box, then output your text to that box with a single line (much 
like the "gprint" function I want to design for gtkmm/C++).

In around 2005 I started programming in Java (no gui).  Then around 2010 
I started programming in Java GUI.  In 2011 I started programming for 
the Android.  The interface basically used  a screen for drawing the 
window, then a single line to update the text in the window.  I started 
doing the same with Java Applications and Java Applets early this year.

Last month I started trying to do the same thing that I was doing with 
Java (Applications, Applets, and the Android) with C++ via Gtkmm... thus 
hear I am.

So, I'm not new to programming, but "playing" around with software 
design extensions is probably something new.

Somewhere in between those stages I played with python, mono, and a few 
other languages.  But I never did much productive work, just experiments 
with them.

All the others has easy ways of updating the gui window.  At first Gtkmm 
appeared to be the only interface that didn't have an easy way to update 
the gui window with new text.  The more I "play" with it, the more it 
appears to be rather easy.  I don't believe it's as complicated as many 
appears to be saying it is.  Looking at most of Alan's messages I 
believe he gave me most of the code from his phone while he was 
traveling.  A couple of times he asked me to wait a couple of days while 
he got to his computer so the he could run some test.

So, most likely the best answer is that I'm just starting out, "playing" 
with software design extensions... maybe in the most definitive terms, I 
might not have quiet started out yet.  I'm mainly just using the simple 
lines of code provided to me by Alan and Kjell and sending text to the 
gui window.

At present it's working perfectly.  Basically I just want to display 
text to my clients in some manner that it doesn't appear as if the OS is 
broken.  Most of the times when I ask a client to read to me what they 
see, when they see a black screen, they say they don't see anything.  It 
takes a while for them to realize the black screen has usable 
information.  I'm starting to send the same text to a graphical window.  
My clients has no problems reading that screen and relating to me what 
they see.
