QWizard::registerField use NOTIFY feature of properties

If you have a property like this:

Q_PROPERTY(QStringList files READ getFiles WRITE setFiles NOTIFY filesChanged)

You still have to connect NOTIFY feature manually, by e.g.

registerField("files*", m_ui->fileListWidget, "files", SIGNAL(filesChanged()));

But I don't see any reason, why qt couldn't select automatically the signal, so it is not anymore necessary to mention it in signature.
