How do I get QObject::tr("%n apple(s)", "", n) to work?

[bmn]

I'm expecting the following behavior:

QObject::tr("%n apple(s)", "", 0) == QString("0 apples")
QObject::tr("%n apple(s)", "", 1) == QString("1 apple")
QObject::tr("%n apple(s)", "", 2) == QString("2 apples")

What I get instead is

QObject::tr("%n apple(s)", "", 0) == QString("0 apple(s)")
QObject::tr("%n apple(s)", "", 1) == QString("1 apple(s)")
QObject::tr("%n apple(s)", "", 2) == QString("2 apple(s)")

I thought this would work out of the box for English, but apparently it doesn't. Do I have to provide an English translation for English?

Unfortunately, the word "tr" is too short for the forums' search function.

Yes you have to do translation for English if you want to handle plurals. See here: http://developer.qt.nokia.com/doc/qt-4.8/i18n-source-translation.html#handling-plurals

You're right, I didn't realize that they had a "No Translation" column. Thank you, Marek!
