Qt 5 QDialogButtonBox translate not working

[mero]

Hello,

I switched from Qt 4 to Qt 5 and everything is working, but all buttons from QDialogButtonBox are not translating


This is my cmake:



set (TRANSLATION_SRCS
qt_pl.ts
scc_pl.ts
)

set (TRANSLATION_QM
qt_pl.qm
scc_pl.qm
)

# translation
qt5_add_translation (TRANSLATION_FILES ${TRANSLATION_SRCS})
add_custom_target (translations DEPENDS ${TRANSLATION_FILES})

# translations
add_dependencies (scc translations)

# install
if (UNIX AND NOT APPLE)
install (FILES ${TRANSLATION_QM} DESTINATION ${SCC_DATA_DIR}/translations)
endif (UNIX AND NOT APPLE)


how I load translate (with debug)


// load translate
QString q = QString("qt_%1").arg(strLanguage);
qDebug() << "path:" << q;
bool load = qtTranslator.load(q, QLibraryInfo::location(QLibraryInfo::TranslationsP ath));
qDebug() << "load:" << load;
if (load)
qApp->installTranslator(&qtTranslator);

if (sccTranslator.load(QString("%1/translations/scc_%2").arg(path, strLanguage)))
qApp->installTranslator(&sccTranslator);


debug result:


path: "qt_pl"
load: true


Normal load translate:


// load translate
if (qtTranslator.load(QString("%1/translations/qt_%2").arg(path, strLanguage)))
qApp->installTranslator(&qtTranslator);

if (sccTranslator.load(QString("%1/translations/scc_%2").arg(path, strLanguage)))
qApp->installTranslator(&sccTranslator);

How it looks in qt creator: (good-translated)
10498

and how it looks in application: (wrong-not translated)
10499

so, what I do wrong ?
and why load returns true and button is not translated ?

I'm using Qt 5.3.1 mingw
