 * \class QS60MainAppUi
 * \obsolete
 * \since 4.6
 * \brief Helper class for S60 migration
 *
 * The QS60MainAppUi provides a helper class for use in migrating from existing S60 based
 * applications to Qt based applications. It is used in the exact same way as the
 * \c CAknAppUi class from Symbian, but internally provides extensions used by Qt.
 *
 * When modifying old S60 applications that rely on implementing functions in \c CAknAppUi,
 * the class should be modified to inherit from this class instead of \c CAknAppUi. Then the
 * application can choose to override only certain functions.
 *
 * For more information on \c CAknAppUi, please see the S60 documentation.
 *
 * Unlike other Qt classes, QS60MainAppUi behaves like an S60 class, and can throw Symbian
 * leaves.
 *
 * \sa QS60MainDocument, QS60MainApplication
