How to have a translated installer with Qt Installer Framework?

[julia_f]

Hello all,

I would like to create a multi-language installer with Qt Installer Framework.

My goal is to have the same used language by the OS. I know that I must put qm files somewhere and modify a xml package like that :

http://doc.qt.io/qtinstallerframework/ifw-customizing-installers.html#translating-pages

http://doc.qt.io/qtinstallerframework/ifw-component-description.html

My question is where to find generic qm files / how to generate them / where to put it. I wish have a translated installer for all Qt String not my custom Strings cuz I never add new Strings

ps : I discovered that "windeployqt.exe" or "macdeployqt" exe generates a directory named "translations" with a lot of qm files : "qt_en.qm", "qt_es.qm", "qt_de.qm", "qt_fr.qm", ... I don't know if it's usefull

ps2 : qm file formet is a binary file format not a xml file format or a text file format

Thanks in advance

It works now!

I added those lines in the "installscript.qs" file :

Component.prototype.retranslateUi = function()
{
    component.languageChanged();
}

and I added those in "config.xml" file :

<Installer>
    ...
    <Translations>
        <Translation>fr.qm</Translation>
    </Translations>
</Installer>
