how to use tr() for QMessageBox?

**gfunk** · 15th November 2007, 19:20

I'm displaying a simple Yes/No QMessageBox. This works fine in English. However, I want to internationalize this for French, so that it displays Oui/Non instead. Is there an easy way to change the text in the buttons for Yes/No?

There's no easy way, but a standard one: http://doc.trolltech.com/4.3/i18n.ht...e-translations

Hi,

Qt Code:

Switch view

QMessageBox messageBox(tr("Info"),
				tr("My message translated"),
				QMessageBox::Question,
				QMessageBox::Yes | QMessageBox::Default,
				QMessageBox::Cancel | QMessageBox::Escape,  //This makes "Esc" key to Cancel the Dialog
				QMessageBox::NoButton,
				this);
//Set the translation text of the buttons. Here you need to have a QTranslator installed that will translate the "Yes" and "No" texts:
			messageBox.setButtonText(QMessageBox::Yes,tr("Yes"));
messageBox.setButtonText(QMessageBox::Cancel,tr("Cancel"));

QMessageBox messageBox(tr("Info"),
				tr("My message translated"),
				QMessageBox::Question,
				QMessageBox::Yes | QMessageBox::Default,
				QMessageBox::Cancel | QMessageBox::Escape,  //This makes "Esc" key to Cancel the Dialog
				QMessageBox::NoButton,
				this);
//Set the translation text of the buttons. Here you need to have a QTranslator installed that will translate the "Yes" and "No" texts:
			messageBox.setButtonText(QMessageBox::Yes,tr("Yes"));
messageBox.setButtonText(QMessageBox::Cancel,tr("Cancel"));

What version of Qt are you using?

This should work for 4.2.2 (it does for me):

Qt Code:

Switch view

QT_TRANSLATE_NOOP("QDialogButtonBox", "&Yes");
QT_TRANSLATE_NOOP("QDialogButtonBox", "&No");

QT_TRANSLATE_NOOP("QDialogButtonBox", "&Yes");
QT_TRANSLATE_NOOP("QDialogButtonBox", "&No");

Check QDialogButtonBox.cpp for other strings to translate

You should load a Qt library translator. There are some translators in %QTDIR%\translations which translate every user visible text in Qt library. French one is incomplete, but you may modify it in linguist.

Qt Code:

Switch view

QTranslator *qtTranslator  = new QTranslator;
QTranslator *appTranslator = new QTranslator;
qtTranslator->load(
	QString("qt_%1").arg(lang),
	QLibraryInfo::location(QLibraryInfo::TranslationsPath)
);
appTranslator->load(...); // Load your translator
 
installTranslator(appTranslator);
installTranslator(qtTranslator);

QTranslator *qtTranslator  = new QTranslator;
QTranslator *appTranslator = new QTranslator;
qtTranslator->load(
	QString("qt_%1").arg(lang),
	QLibraryInfo::location(QLibraryInfo::TranslationsPath)
);
appTranslator->load(...); // Load your translator

installTranslator(appTranslator);
installTranslator(qtTranslator);
