Would it be okay if the QTemporaryFile is allocated on the stack? e.g.

  QTemporaryFile keymapFile;

(asking out of curiosity)

Noob question: why do we need another QFile object?

I'm just trying to understand why we can't do something along these lines

  tmp->setPermissions(QFileDevice::ReadOwner);
  m_seat->setKeymap(tmp->handle(), size);
