Qt 5 QDialogButtonBox translate not working

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:

Code:

---

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)

Code:

---

// load translate
    QString q = QString("qt_%1").arg(strLanguage);
    qDebug() << "path:" << q;
    bool load = qtTranslator.load(q, QLibraryInfo::location(QLibraryInfo::TranslationsPath));
    qDebug() << "load:" << load;
    if (load)
        qApp->installTranslator(&qtTranslator);
 
    if (sccTranslator.load(QString("%1/translations/scc_%2").arg(path, strLanguage)))
        qApp->installTranslator(&sccTranslator);

---

debug result:

Code:

---

path: "qt_pl"
load: true

---

Normal load translate:

Code:

---

// 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)
Attachment 10498

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

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

I'm using Qt 5.3.1 mingw
