  \class QS60MainAppUi

  \since 4.6

  \brief The QS60MainAppUi class is a helper class for S60 migration.

  \warning This class is provided only to get access to S60 specific

  functionality in the application framework classes. It is not

  portable. We strongly recommend against using it in new applications.

  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.
