Thank you Andrew.
I misunderstood your first message and am looking at it more in depth
as well as your current post.
You bring up a very important clarification I should make from my
original post in this thread. I should not have counted the comments as
part of the total number of lines. Sometimes I post something, and have
an after though, but believe the general membership would see beyond my
error.
When excluding the important and very well documented comments of
Kjell's example it comes up to nearly have my original number. The
lines of code is about 235. Most of the confusion (for me) is the 11
widgets that, when I try to eliminate, breaks the code and I can't get
it to work. I'm sure, eventually I'll figure it out, the same way if a
person looked at the code for LibreOffice, and spent a lot of time
analyzing and breaking it down.
When I first started programming and was able to output a "Hello World",
I was happy. It worked. I made lots of changes and understood it.
When I performed my first I/O it was just a minimum number of lines and
did a strictly limited task. I was able to dissect it in one short
session, then start using it productively in my crude programs.
I'm trying to find this same strict focus with outputting and updating
the gtkmm gui (without user input). If I can understand this, I'll have
a foundation of which I could build upon.
Kjell's example has everything I'm looking for, inclusive. But with my
current understanding of gtkmm, it's too complex for me to be able to
use. If all the widgets were eliminated and it just had a simple gui
window, it would be a bit easier for a beginner to work with.
At a glance it appears that you might have provided the needed solution
(possibly in your first message last week). I apologize for missing
some of the gist, but I will spend a lot of time studying in minute
detail everything you have posted. I appreciate your asking me to point
out what might be insufficient.
I also appreciate Kjell's invitation for the community (including me) to
comment on problems with his example. I'm sure, for experts there would
hardly be any problems. It was very easy to compile. It has a lot
included. However, for a novice, it's a bit overwhelming because it
includes so much. A novice might have to keep everything intact to
ensure that the code will compile, then try to figure out where to put
his functions. As I mentioned, in my case, if I remove the buttons and
progress bars, it becomes broken and I have to start back over with the
full code and try a different approach.
I would like to apologize to the community for being so new and using so
many words to explain my problem. But if I use a minimum amount of
words, someone might spend hours trying to help, but might come up with
something that doesn't address the problem. So I' trying to make the
problem clear, so that whatever time and energy anyone applies would
more likely answer the question.
Thanks!
