Indicating what to translate
Include QTranslator:
#include <QTranslator>
and wrap any strings with the QApplication::translate()
or the QObject::tr()
function:
QString message = app->translate("Message displayed while the system is loading", "Loading, Please Wait...");
Providing the translations
First, add each language file to the TRANSLATIONS
variable:
TRANSLATIONS = myApp_en.ts \ myApp_fr.ts
Run lupdate
on the project:
lupdate myApp.pro
Provide the translations:
linguist *.ts
Release the translations:
lrelease myApp.pro
Installing translations
Load the translation file before displaying any translated windows:
if (!translator.load(QString("myApp_") + lang + ".qm")) { qDebug("!!! translator.load -> FALSE !!! \n"); } else { app->installTranslator(&translator); } main = new MainWindow();
