QString::null

[Asperamanca]

I'm a bit puzzled about using or avoiding QString::null. I understand, it's equivalent to QString(), but there's no mention in the documentation (not even as obsolete), only a "compatibility" comment in qstring.h

    // compatibility
    struct Null { };
    static const Null null;

Is it considered obsolete?

Pretty much, you should generally avoid it. Use QString::isEmpty instead.

And how about for setting strings?

void showWarning(const QString& message, const QString& context = QString::null);

Use a default constructed QString.

void showWarning(const QString& message, const QString& context = QString());
