QWizard on Symbian S60 doesn't support the Cancel button

QWizard that has a Cancel button is not functional in Symbian S60 devices.

The Cancel button should be visible/selectable in a soft menu or Options menu.

In addition, the Cancel button should also support custom label (just like in desktop platforms, i.e. can rename Cancel button label to "Exit").

may illustrate this problem.
