    corresponding icons.

    Note: This class is a subclass of CpBaseSettingView for compatibility with Control Panel
          framework.  However, it does not use HbDataForm as its widget and as its parent does, so
          it uses SetWidget to set the listview to its widget instead of an HbDataForm.
