Qt tr does not seem to work on static constant members?

Question

I'm working on translating our Qt gui at the moment.

I have the following code:

// header file
static const QString Foo;

// cpp file
const QString FooConstants::Foo = "foo"; 

// another cpp file
editMenu->addAction(tr(FooConstants::Foo));

This doesn't seem to work though.

That is, there is no entry in the .ts file for the above constant.

If I do this then it works:

// another cpp file
editMenu->addAction(tr("foo"));

However, this constant is used in many places, and I don't want to have to manually update each string literal. (if it were to change in the future)

Can anyone help?

Wrap your literal in the QT_TR_NOOP macro:

// cpp file
const QString FooConstants::Foo = QT_TR_NOOP("foo");

From the guide:

If you need to have translatable text completely outside a function, there are two macros to help: QT_TR_NOOP() and QT_TRANSLATE_NOOP(). They merely mark the text for extraction by the lupdate tool. The macros expand to just the text (without the context).
