[SOLVED] Qt translation not working

tomko222

I tried to add multilanguage support in my new program so I just added same code as in my other program where translations were working. But in this case everything remains untranslated... TRANSLATIONS += translation-pl_PL.ts added to .pro file, .ts translated, .qm generated and added to resources (/translations/translation-pl_PL.qm) so I don't think I forgot about doing something necessary...

main.cpp where translation is loaded:
@
#include "mainwindow.h"
#include <QtGui>
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
QTextCodec::setCodecForTr(QTextCodec::codecForName("UTF-8"));

//checking available program translations
QFile tempFile&#40;":/translations/translation-"+QLocale::system(&#41;.name(&#41;+".qm");
if(tempFile.exists())
{
    //program is translated to system default language
    qDebug("translation to system default language available");
    //Qt translations
    qDebug("loading qt translations");
    QTranslator qtTranslator;
    bool check;
    check=qtTranslator.load("qt_"+QLocale::system&#40;&#41;.name(&#41;, QLibraryInfo::location(QLibraryInfo::TranslationsPath));
    if(check)
    {
        qDebug("qtTranslator load true");
    }else{
        qDebug("qtTranslator load false");
    }
    a.installTranslator(&qtTranslator);

    //program translations
    qDebug("loading program translations");
    QTranslator programTranslator;
    check=programTranslator.load(":/translations/translation-"+QLocale::system&#40;&#41;.name(&#41;);
    if(check)
    {
        qDebug("programTranslator load true");
    }else{
        qDebug("programTranslator load false");
    }
    a.installTranslator(&programTranslator);

}
MainWindow w;
w.show();

return a.exec(&#41;;

}
@

Debug info:
@
translation to system default language available
loading qt translations
qtTranslator load true
loading program translations
programTranslator load true
@
So everything is loading but translation is not working...

What can be wrong here?

Hi and welcome to devnet,

Are you sure that you are not getting the english translator ?

Did you add tr() around your texts ?

tomko222

pl_PL translator is loaded. I have tr().

SGaist

The are you sure that the translation file contains the correct texts ?

tomko222

.ts is translated - I can see translations inside it. .qm is generated from it so I think that it should be ok too.

SGaist

If you have the translation files from your other programs handy, can you try to use one of them to see if it behaves better ?

tomko222

I found what was the problem... I defined qtTranslator and programTranslator in if...

Great you found out !
