No problem: the iterator is a pointer in a UTF-8 encoded string and the function (called next) has to advance to the next code point (1, 2, 3 or 4 char). If iterator is at end of string it doesn't advance.
Although a very simple function, I had a number of design decisions to make:
- How should I deal with improperly encoded UTF-8 strings? I decided to return false if the string is not properly encoded.
- Should I just leave out the boundary check and just document it? I decided against as it would have been unsafe.
And the last one I was asking about: For limit check, should I just pass the string or the end iterator.
It means that your "tcbcollecter" list was empty when you assigned the "tcbitrate" iterator. Calling begin() on an empty list will give you the end() iterator, because there is no real element to point to. You can't dereference it because it doesn't point at anything.
Was thinking how to that don’t know if it’s practical my list represents the output of VSMLIST z/os assembler mainframe macro representing the amount allocate free and I unallocated storage for an address space
It’s listed by storage blocks ( address and length ) storage descriptors representing a storage subpool which different attributes and storage keys and the TCB task control blocks of the task that own them
Forgive me to be so bold - but I just cannot believe that in versatile forum like
this there is nobody who can at lest give me some idea how to resolve this.
It seems to be a problem that everybody wants SINGLE system problem
- that seldom works in real life.
As the title suggest - I need to connect Qt generated object / window to Linux "terminal"
(operating system ) native window.
I can highlight ( Using Qt) the text in the native window (!)
but Qt gives me no indication it did that.
PLEASE - NO PASSING THE BUCK TO QT FORUM - THEY HAVE NO IDEA HOW TO PROCEED - IT IS NOT Qt ISSUE IN THEIR ASSESSMENT -HENCE out OF THEIR narrow minded LEAGUE.
ps i WILL REMOVE THIS , AND MY SIMILAR POSTS, IF i DO NOT GET REASONABLE REPLY , JUST TO SAVE SPACE HERE.
Edited / addendum
I am still looking for somebody who is willing to help me instead of just posting text.
If it bothers you that my post is not specifically C/C++ code , please ignore it .
If it bothers you that my post is too complex , please ignore it also.
If it bothers you that my post is poorly written - read how to post / answer questions.
Is short - write something helpful and constructive.
"Terms and conditions apply to your answer."
You're doing it again, and you wonder why nobody, in any forum, is willing to even talk to you, let alone help you.
How does terminal created window "connect" to Qt ? - that is the question.
And as so often suggested, that is a question for a QT forum and has nothing to do with C/C++. Unless you can show some actual code and explain (without all the unnecessary orders) what the problem is, there is very little anyone here can do to help you. So try this template:
In the following code, the instruction at line x throws an out of range exception, even though the calculation appears to be correct. blah blah ...
intvalue = 5;
// some stuff
} while (values <10);
That's all we need, not a load of 'instructions' about how we must answer your questions in a form that you think you deserve. Remember, we are all volunteers here and actually do this because we like to help people. What we do not care for is being given orders, especially by those who somehow think we are their employees.
I am sorry, but whatever the people at QT say, this is purely a QT question. Every single line in that code is using a QT command or object so that is where the answer(s) lie.

how to "link " Qt process created terminal window with Qt running application.
Not sure what you mean by that. The started terminal is a separate process, so the only connection between the two is the process id which allows the caller to determine whether the started process is running or not.
I suspect that what's going on is that when you highlight some text in your terminal window, its getting copied to a clipboard in the GUI. Or perhaps its not getting copied and you need to tell the terminal app to copy the text - usually, but not guaranteed to be, CTL-C. Otherwise, you might need to look into the GUI API for accessing contents of the clipboard. Note that many XTerm emulators seem to have 2 independent clipboards. There's one that you get when you merely highlight the text, and which you can then usually paste with middle-button on the mouse. There's also the Cut/Paste (CTL-C/CTL-V) clipboard. The two sometimes seem to be synchronized, but not always. In general, I think you should prefer the Cut/Paste method, as that seems to copy text to the GUI's idea of the clipboard, and is usually what you get back when you Paste. This is all a bit hand-wavy, because it seems like there's no hard and fast rules about what gets copied where during a highlight and/or a Copy/Paste.
When you highlight text in a terminal it can usually then be copied by some keystrokes or menu option. That is fairly standard throughout Windows, MacOS and Linux. You can then paste it into another running application (e.g. the QT process that launched the terminal), but as far as I am aware you still need to do it manually. If you want direct connection between a calling and called process, then the called process needs to be a console type application. You can then connect the stdout of the called process to stdin of the caller, so the caller can read what the called process writes. The QProcess documentation explains how to do it.
