I'm trying to translate my app and the only thing that i can translate is the Qt texts with loading "qt_pt.qm" but when I try to load my "app.qm" the text doesn't get translated.

I've tried everything i know, but it isn't working.

So, made another project and tried to translate words in Console App, same problem.

Can you help me ?

This is the .ts file:

Qt Code: 
  1. <?xml version="1.0" encoding="utf-8"?>
  2. <!DOCTYPE TS>
  3. <TS version="2.0" language="pt" sourcelanguage="en">
  4. <context>
  5.     <name></name>
  6.     <message>
  7.         <source>old</source>
  8.         <translation>velho</translation>
  9.     </message>
  10.     <message>
  11.         <source>novo</source>
  12.         <translation>new</translation>
  13.     </message>
  14. </context>
  15. </TS>
To copy to clipboard, switch view to plain text mode 

This is my code:

Qt Code: 
  1. #include <QtCore/QCoreApplication>
  2. #include <QTranslator>
  3. #include <QDebug>
  4.  
  5. int main(int argc, char *argv[])
  6. {
  7.     QCoreApplication a(argc, argv);
  8.  
  10.     qDebug() << "loaded: " << tr->load("translator.qm", "C:\\C++\\Qt Projects\\Translator\\Translator");
  11.  
  12.     qDebug() << "------------------";
  13.     qDebug() << QObject::tr("old");
  14.     qDebug() << QObject::tr("velho");
  15.     qDebug() << QObject::tr("new");
  16.     qDebug() << QObject::tr("novo");
  17.     qDebug() << "------------------";
  18.  
  19.     a.installTranslator(tr);
  20.  
  21.     qDebug() << "------------------";
  22.     qDebug() << QObject::tr("old");
  23.     qDebug() << QObject::tr("velho");
  24.     qDebug() << QObject::tr("new");
  25.     qDebug() << QObject::tr("novo");
  26.     qDebug() << "------------------";
  27.  
  28.     return a.exec();
  29. }
To copy to clipboard, switch view to plain text mode 

and I get this output:

Qt Code: 
  1. loaded:  true
  2. ------------------
  3. "old"
  4. "velho"
  5. "new"
  6. "novo"
  7. ------------------
  8. ------------------
  9. "old"
  10. "velho"
  11. "new"
  12. "novo"
  13. ------------------
To copy to clipboard, switch view to plain text mode 

It doesn't translate my text, link in my App, what I can do ?
What is wrong in the code ?
What I need to do to fix it ?
