    @SGaist said:

    To add to @kshegunov , the note concerns the use of QTranslator shown in the example i.e. setup of the language at application startup and no support of dynamic translations.

    How the application doesn't support dynamic translations? Take a look into this line it calls changeEvent and if you run the app. you'll find that Tester loads the translations dynamically correctly while it doesn't call translations for static library widget because I don't know how to do it!

    How the application doesn't support dynamic translations?

    He was referring to the note in the documentation I was citing, and was explaining that it is only relevant when there is no support for dynamic translation.

    it doesn't call translations for static library widget because I don't know how to do it!

    You do it, like you're doing it now. Here's the thing, a static library is nothing more then a bunch of .obj files put together. Linking a static library just includes them into your application's binary. This means, that there is nothing different between widgets that come from a static library and these declared in your application (see @AlterX's comment, he mentioned that). That's why I said you're asking the wrong question. Your translation loading looks perfectly fine to me, and it has nothing to do with static or dynamic libraries - you need to look elsewhere to solve the problem. Do you have any output in the creator's windows that might suggest your translation is not loaded? Do you get the "Failed to load a translation for QT in your local language" message printed?

    I tried to use Q_INIT_RESOURCE as mentioned in this line but unfortunately it makes things worst.

    Yes you should do that for all the resources in your static library. But according to this it should be placed in the beginning of main().

    Kind regards.

      No

      No. I get Failed to load translation from static library error message!

          Hello,
          Something is amiss here, let's take it from the top. You said that you get the "Failed to load a translation for QT in your local language" message, but this message is to be shown when this fails:

              myTranslator->load(*local, QLatin1String("tester"), QLatin1String("_"), QLatin1String(":/i18n"))
          

          This particular line is in your application and tries to load an application translation, where does a static library resource come in play here? Could you tell what is the current language you're using and its iso code (you could use QLocale::language() and QLocale::languageToString), and make sure there's a matching translation file?

          Kind regards.

          Read and abide by the Qt Code of Conduct

            I didn't say that!
            I said I get Failed to load translation from static library which points to myTranslator->load(":/languages/arabic") failure!

            where does a static library resource come in play here?

            As I mentioned above this line suppose to load translation from static library's resource

            Could you tell what is the current language you're using and its iso code

              Indeed you did, it's my mistake, sorry.

              which points to myTranslator->load(":/languages/arabic") failure!

              Could you verify that this file is available? For example what does QFile::exists(":/languages/arabic") return, true or false? If the file exists then the problem is with the actual loading, if the file is not found, then I guess there's a problem with the resource initialization.

              Kind regards.

                After reviewing the project I discovered there are two "resources.qrc" the first one in the static library and the other in tester app. so I supposed this maybe makes Qt confused so I renamed one of them to a different name but unfortunately I still get same result.

                  Hi
                  Maybe try

                  QDirIterator it(":", QDirIterator::Subdirectories);
                      while (it.hasNext()) {
                          qDebug() << it.next();
                      }
                  

                  to have a look how the files are named in the running exe to to verify
                  that they are indeed under ":/i18n" and paths are as you expect.

                    Could you verify that this file is available? For example what does QFile::exists(":/languages/arabic") return, true or false?

                    I get true

                    If the file exists then the problem is with the actual loading, if the file is not found, then I guess there's a problem with the resource initialization.

                    After reviewing the project I discovered there are two "resources.qrc" the first one in the static library and the other in tester app. so I supposed this maybe makes Qt confused so I renamed one of them to a different name but unfortunately I still get same result.

                    What about loading like this:

                        translator->load("arabic", ":/languages");
                    

                    And as a second suggestion: I think you should create another QTranslator object for the second translation file.

                    Kind regards.

                      Thanks. This fixed Tester app. problem but it didn't fix the main problem (loading translation from static library) I still get this error message:

                        And have you tried the loading like this translator->load("arabic", ":/languages");, since you didn't comment on that?

                            Can I ask some silly maybe ?
                            The list shows
                            :/i18n/tester_ar.qm

                            There is no "arabic" under languages
                            there is
                            ":/languages/i18n/WidgetKeyboard_ar.qm"

                              I tried to use translator->load(":/languages/i18n/WidgetKeyboard_ar") instead. The error message disappeared ("Failed to load translation from static library") but the widget comes from the static library still appears in English!

                                Silly question number 2.
                                The test calls ui->retranslateUi(this);
                                void Tester::changeEvent(QEvent *event)
                                {
                                if (event->type() == QEvent::LanguageChange) {
                                ui->retranslateUi(this);
                                } else
                                QWidget::changeEvent(event);
                                }
                                But tester ui->retranslate() knows about the widgets from the library ?
                                retranslateUi() just call all ->setText for elements inserted on the UI.
                                How can it know about widgets in the Lib?
                                Who calls widget_in_lib->setText?

                                  Fair point. But as you can see from the code the widget in static library built manually not by using Qt Designer so retranslate doesn't exist and I don't know how to create an alternative to it :(

                                    well for dynamic translation, meaning load translation AFTER keyboard been created would be to call
                                    void WidgetKeyBoard::createKeyboard(void) again.
                                    As it seems to be the only place with tr(text);
                                    retranslateUi() is very simple in all programs. it simply just sets the texts again
                                    and the tr function gets the new text from the active translation.
                                    Alternatively you need enum all widgets (in keyboard), get the text and re-set it via tr / directly look up trans text.
                                    But it can be messy if many types of Widgets as then u need to handle the "setText" for each.

                                      I tried to call createKeyboard() once again as following but still gives same result although this function calls tr() so it suppose to do what you talked about!

                                      void Tester::changeEvent(QEvent *event)
                                      {
                                          if (event->type() == QEvent::LanguageChange) {
                                              ui->retranslateUi(this);
                                              myKeyboard->createKeyboard();
                                          } else
                                              QWidget::changeEvent(event);
                                      }

                                        Hi
                                        Maybe you can
                                        delete myKeyboard;
                                        myKeyboard = new Keyboard(this);
                                        as im not sure if calling createKeyboard() for same instance is 100% ok. (did not try it)

                                        Then there is the context thing.
                                        for mainwindow, its "mainwindow" (doh), but I do wonder about the translation that comes from static.

                                        Since they are linked into "main", I assume its context is the same as main (tester) but if the
                                        qm is different, it will not work.

                                        So open them (qms) in Linguist and check the context they were extracted as.

                                        then try with
                                        http://doc.qt.io/qt-5/qcoreapplication.html#translate

                                        To test a translation with that context and see if it does resolve.

                                        First then I would worry about tr working in createKeyboard()

                                        If I may say so.

                                        update:
                                        Context is "WidgetKeyBoard"
                                        So calling createKeyboard() should be in the right context as we are in that class.

                                        So testing with qcoreapplication.html#translate
                                        to see if all is loaded and happy.
