@broulik just pointed out that KStandardAction has gained support for the more modern slot syntax.

So, ideally this line should be changed to

  mShowMenuBarAction = KStandardAction::showMenubar(this, &TopLevel::toggleShowMenuBar, actionCollection());

Which has the advantage of letting the compiler assert slot compatibility, whereas the old `SLOT()` syntax turns it into a runtime problem which is easy to miss should it break in the future.

Not technically a blocking issue though.
