QFileDialog::getExistingDirectory does not display files

So I changed

QFileDialog::getExistingDirectory(this, tr("caption"), imagesPath);

to

QFileDialog::getExistingDirectory(this, tr("caption"), imagesPath, 0);

to get rid of the default ShowDirsOnly and show files as well.
But it still only displays folders.

(Also even with DirsOnly it does not land in qt_win_get_existing_directory like the docs suggest.)
