How to concatenate strings+ int in messageBox qt c++?

RuWex

thank you:)
but now I have a problem,
because,
I wanted that not all of the numbers appear, for example just numbers more than 1000 and the other more than 2000...
so I did many many if and paste every time to the debbuger, but now I want it to appear in messageBox once...
do you have any idea how to solve it?

@RuWex
I don't think anyone can understand what you are asking. If you need an if then write one. If you want a function to not print certain numbers so that you can re-use it, write one.

RuWex

I did this function : (you see all the if?) I did what you said its work well! but |I want to paste like I paste in the debugger


bool PrintTimeRemainig(int second)
{
    int days, hours, minutes;
    minutes=60;
    hours=minutes*60;
    days= hours*24;
    int remainingDays=0, remainingHours=0, remainingMinute=0;
    if(second>days)
    {
        remainingDays= second/days;
        second= second%days;
        qDebug()<<"Remaing days:"<< remainingDays<<endl;

    }
    if (second>hours)
    {
        remainingHours= second/hours;
        second= second%hours;
        qDebug()<<"Remaing hours:"<< remainingHours<<endl;

    }
    if(second>minutes)
    {
        remainingMinute= second/minutes;
        second= second%minutes;
        qDebug()<<"Remaing minutes:"<< remainingMinute<<endl;

    }
    qDebug()<<"Remaing seconds:"<< second<<endl;
   

    QString text= QString("Estimated time to complete the test %1 days, %2 hours, %3 minutes, %4 seconds").arg(remainingDays).arg(remainingHours).arg(remainingMinute).arg(second);

    QMessageBox msgBox;
    msgBox.setText(text);
    msgBox.setStandardButtons(msgBox.Ok| msgBox.Abort);
   int ret=msgBox.exec();
   switch (ret) {
        case msgBox.Ok:
       {
           return true;
       }
        case msgBox.Abort:
       {
           return false;
       }


   }
    return false;
}

Sorry, no idea what this means. You do not "paste in the debugger", the debugger is for debugging not for editing. And copy-paste works anywhere.

RuWex

yes, but i just wanted to see if uts work well...
anyway,
do you have any idea what can i do??
if I dont want to paste on the messageBox just what that standing on some condition?

No because as I said I have no idea what you are asking.

Nor do I know what this means.

I will leave you to see if anyone else answers.

Sorry, I'll try to explain myself more clearly, I want to send a message to the user in the messageBox, but I don't want all the %X to be displayed, but only those that meet a certain condition. Does anyone have an idea how to do this?

@RuWex
Instead of your current

QString text= QString("Estimated time to complete the test %1 days, %2 hours, %3 minutes, %4 seconds").arg(remainingDays).arg(remainingHours).arg(remainingMinute).arg(second);

Instead of this fixed string with its %...s and matching arg()s, create a different string with arguments according to your if condition. Or build it up one bit at a time.

Maybe you have in mind something like this:

QString text= QString("Estimated time to complete the test: ");
if (remainingDays > 0)
  text.append(QString("%1 days, ").arg(remainingDays));
if (remainingHours > 0)
  text.append(QString("%1 hours, ").arg(remainingHours));
// and so on

RuWex

ou!
Thanks, this is exactly what I wanted!!

QString text= QString("Estimated time to complete the test: ");

QString text= tr("Estimated time to complete the test: %n day(s)").arg(remainingDays);

;)

@Christian-Ehrlicher
I don't follow?! I don't think you're pointing out the tr(), I don't know what your %n is about, and OP wants the Estimated time .... at the start unconditionally....
I think you're trying a piece of humor that is too droll/subtle for me to grasp?

No, it's the correct way to translate a string for singular/plural - we discuessed this some days ago already.
See https://doc.qt.io/qt-6/i18n-source-translation.html#handling-plurals

@Christian-Ehrlicher
Ohhhhhhhh.... Well I'm certainly not writing this for Polish/Russian!
My look up of QString::arg() did not show any %n?
And if we are going to be that fussy, will %n day(s) come out as 1 day [sic.] if n == 1??

Oh I see, it's in that link.

OK, @Christian-Ehrlicher, how about this then: I want the count in the message to be on sheep. yes, that's right, how many sheep something takes. How do I do that cross-language then?

%n sheep(s) --- wrong for English in plural
%n sheep --- wrong for French etc. in plural

? ;-)

You have to enter two translations in linugist then (or more for other languages). But there is only one tr() call in your code.
