   \class QPEApplication qpeapplication.h
   \brief The QPEApplication class implements various system services
     that are available to all Qtopia applications.
 
   Simply by using QPEApplication instead of QApplication, a plain Qt
   application becomes a Qtopia application. It automatically follows
   style changes, quits and raises, and in the
   case of \link docwidget.html document-oriented\endlink applications,
   changes the current displayed document in response to the environment.

   by more than the normal passage of time.
 */
 
 /*!
   \fn void QPEApplication::clockChanged( bool ampm );
 
   This signal is emitted when the user changes the style
   of clock. If \a ampm is TRUE, the user wants a 12-hour
   AM/PM close, otherwise, they want a 24-hour clock.
 */

   \fn void QPEApplication::appMessage( const QCString& msg, const QByteArray& data )
 
   This signal is emitted when a message is received on the

   The slot to which you connect this signal uses \a msg and \a data
   in the following way:
 
 \code
