How to set selected filter on QFileDialog?

I have a open file dialog with three filters:

QString fileName = QFileDialog::getOpenFileName(
        this,
        title,
        directory,
        tr("JPEG (*.jpg *.jpeg);; TIFF (*.tif);; All files (*.*)")
);

This displays a dialog with "JPEG" selected as the default filter. I wanted to put the filter list in alphabetical order so "All files" was first in the list. If I do this however, "All files" is the default selected filter - which I don't want.

Can I set the default selected filter for this dialog or do I have to go with the first specified filter?

I tried specifying a 5th argument (QString) to set the default selected filter but this didn't work. I think this might only be used to retrieve the filter that was set by the user.
