Yes/No message box using QMessageBox

Question

How do I show a message box with Yes/No buttons in Qt, and how do I check which of them was pressed?

I.e. a message box that looks like this:

Answer 1

I'm missing the translation call tr in the answers.

One of the simplest solutions, which allows for later internationalization:

if (QMessageBox::Yes == QMessageBox::question(this,
                                              tr("title"),
                                              tr("Message/Question")))
{
    // do stuff
}

It is generally a good Qt habit to put code-level Strings within a tr("Your String") call.

(QMessagebox as above works within any QWidget method)

EDIT:

you can use QMesssageBox outside a QWidget context, see @TobySpeight's answer.

If you're even outside a QObject context, replace tr with qApp->translate("context", "String") - you'll need to #include
