In the end everything was fine with the example above.
I just had to update and release my translation files, because in the meantime I changed the name of a .qml file, and the filename is directly linked into the .ts files created by linguist and used by Qt.
I feel a bit ashamed but yes, it was really trivial and kinda stupid :)

You're welcome.
Happy coding!

Edit:
Btw, moving the keys to the function should also work:

void ZellerGUI::on_yearEdit_editingFinished() { // If this is initialized here it should work okay static const char * const days[7] = { QT_TR_NOOP("Monday"), QT_TR_NOOP("Tuesday"), // ... and so on }; // ... calculate day QString day = QCoreApplication::tr(days[calculatedDay - 1]); ui->resultEdit->setText(day); }

Thanks for the advice mrjj. I used the translate functions and the save and restore to ensure that each section has a logical coordinate system that makes sense to it.

Hi,

You should rather store the original error message in the database and to the translation when showing the database content.

I am having this exact problem. I compiled my project for an embedded arm device, linux desktop, and windows desktop. The windows and linux hosts display the characters correctly, where the embedded device just shows nothing.

I'm using the Noto fonts https://www.google.com/get/noto/#sans-hans and am positive it is being used on the linux desktop, since if I don't copy the font into the same directory as the application, it just shows blocks. When the font is in the directory, it shows everything properly.

I tried the same thing with the embedded build, and nothing shows up. The font being loaded, since if it's not in the directory, it complains that it can't load it. Is there some extra switch or rendering tool/application that embedded linux needs? I've tried with both 'linuxfb' and 'egl' platforms with no success.

Thanks in advance for any help.

Hi I think you can have multiple translators(file) active, so when you switch language
its best to remove old one or it might get messy as the old one would also be searched.
But if completely different language, i doubt anything crazy will happen.

Don't worry, that kind of things happens frequently ;)

You're welcome !

Since you have it working now, please mark the thread as solved using the "Topic Tool" button so other forum users may know a solution has been found :)

Finally I'm able to automatically copy the qt translation files and create resource file from the pro file:

TRANSLATIONS = myapp_cs.ts \ myapp_xx.ts QT_TRANSLATIONS = qtbase_cs.qm #------------------------------------------------- # create lang folder QM_DIR = $$shadowed($${PWD})/lang mkpath($${QM_DIR}) mkpath($${QM_DIR}/lang) #------------------------------------------------- # copy system translation files to lang folder for(FILE,QT_TRANSLATIONS){ FILE = $$shell_path($$[QT_INSTALL_TRANSLATIONS]/$${FILE}) system($${QMAKE_COPY} $${FILE} $$shell_path($${QM_DIR}/lang)) } #------------------------------------------------- #generate qm files directly from qmake for(FILE,TRANSLATIONS){ QM_FILE = $$shell_path($${QM_DIR}/lang/$$replace(FILE,.ts,.qm)) system(lrelease $${FILE} -qm $${QM_FILE}) } #------------------------------------------------- #create resource file with translations win32:system(cd $$shell_path($${QM_DIR}) & rcc --project -o lang.qrc) unix:system(cd $$shell_path($${QM_DIR}) ; rcc --project -o lang.qrc) RESOURCES += $${QM_DIR}/lang.qrc #------------------------------------------------- # extra target to generate ts translation files lupdate.commands = lupdate $$_PRO_FILE_ lupdate.depends = FORCE QMAKE_EXTRA_TARGETS += lupdate #------------------------------------------------- # extra compiler to generate qm translation files lrelease.input = TRANSLATIONS lrelease.output = $${QM_DIR}/lang/${QMAKE_FILE_BASE}.qm lrelease.commands = lrelease ${QMAKE_FILE_NAME} -qm ${QMAKE_FILE_OUT} lrelease.CONFIG += no_link target_predeps QMAKE_EXTRA_COMPILERS += lrelease

@SGaist OK. Thanks for the answer. I'll give a try.

The standard translations for Ok, Cancel, Save had been moved into <name>QPlatformTheme</name>
They are missing now in all the old qt_??.ts and are only available in the newer qtbase_??.ts

I had copied the QPlatformTheme messages into the ts-files I needed.

Are you loading all the necessary translation files ?
