Qgis C++ plugin translation

Question

I'm having issues with the translation of my Qgis plugin.

static const QString sName = QObject::tr( "Editeur Monoscopique 3D" );

MyClass::MyClass( QgisInterface * theQgisInterface ): QgisPlugin( sName) {

QSettings tSettings;
QString qsUserLocale = tSettings.value( "locale/userLocale", "" ).toString();

    if ( ( qsUserLocale != "fr_FR" ) && ( qsUserLocale != "fr" ) )
    {
            QString qsTranslationPath = ":/prefix/en_US.qm" ;
            QFileInfo tFileInfo (qsTranslationPath) ;
            if (tFileInfo.exists())
            {
                    //QTranslator translator;
                    if (m_tTranslator.load( "en_US", ":/prefix" ) )
                            qApp->installTranslator(&m_tTranslator);
            }
    }

}

The problem is that sName is declared before installing the translator
qApp->installTranslator(&m_tTranslator); and so its text is not translated !
How can I fix this?

Answer 1

You need to implement name() anyway, so I would consider sName as the internal name and set up another member value to hold the user-visible name. Set its final value after installing the translator and most cases should be covered.
