Is there a way to use the translations from qt library combined with that from user's application?

[Sauntor]

If your app has its own translation files(myapp.ts) and it supplies a About Qt dialog via QMessageBox::aboutQt(), then, the message shown by aboutQt() will not be translated!
What's the solution? Or there is no solution?

@Chris-Kawa After trying, I find it out.
Each QTranslator can only hold the translations it load() at last.
But one QCoreApplication can installTranslator() for many times and use all of them for translating😂

So, the solution is creating one QTranslator for Qt, and one for your app, finally, install them all to your app.

You need to deploy Qt modules translation files located in your Qt installation directory along with translation files of your app. See the documentation.

@Sauntor Or, like the documentation I linked suggests, merge all translations into one file using lconvert.
