    See the QString documentation - either QString::number() or QString::arg(). And if you want to make your application translateable than take a look at QObject::tr()

    /JonB was faster :)

      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?

        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.

            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.

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

                if I dont want to paste on the messageBox just what that standing on some condition?

                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?

                    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

                          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

                              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

                              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
                              

                              ? ;-)

                                @JonB said in How to concatenate strings+ int in messageBox qt c++?:

                                %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.
