space around `|`

`m_newName` is only used in the constructor, no need for it to be a member

is this correct for e.g. `foo.jpeg`? - the preferred extension is `jpg`, so this may select to many characters

> renamefiledialog.cpp:104
> +        // If the current item is a directory, select the whole file name.

the `!isDir()` should apply to the whole block, i.e. create the QMimeDatabase instance only if needed

> renamefiledialog.cpp:121
> +        QSet<QString> extensions;

`qAsConst(m_items)`

> renamefiledialog.cpp:122
> +        foreach (const KFileItem& item, m_items) {
> +            QMimeDatabase db;
> +            const QString extension = db.suffixForFileName(item.url().toDisplayString().toLower());

move db instance out of loop

> +            if (extensions.contains(extension)) {
> +                m_allExtensionsDifferent = false;

better name - `m_extensionsAreUnique`

> renamefiledialog.cpp:174
> +        job = KIO::moveAs(oldUrl, newUrl, KIO::HideProgressInfo);

`m_renamedItems.reserve(m_items.count())` in this block
