   \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 standard 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 currently displayed document in response to the environment.
- 
+
   To create a \link docwidget.html document-oriented\endlink
   application use showMainDocumentWidget(); to create a
   non-document-oriented application use showMainWidget(). The
   keepRunning() function indicates whether the application will
   continue running after it's processed the last \link qcop.html
   QCop\endlink message. This can be changed using setKeepRunning().
- 
+
   A variety of signals are emitted when certain events occur, for
   example, timeChanged(), clockChanged(), weekChanged(),
   dateFormatChanged() and volumeChanged(). If the application receives
   a \link qcop.html QCop\endlink message on the application's

   are emitted when synching begins and ends respectively - upon these
   signals, the application should save and reload any data
   files that are involved in synching. Most of these signals will initially
   be received and unfiltered through the appMessage() signal.
- 
+
   This class also provides a set of useful static functions. The
   qpeDir() and documentDir() functions return the respective paths.
   The grabKeyboard() and ungrabKeyboard() functions are used to
   control whether the application takes control of the device's
   physical buttons (e.g. application launch keys). The stylus' mode of
   operation is set with setStylusOperation() and retrieved with
   stylusOperation(). There are also setInputMethodHint() and
   inputMethodHint() functions.
