/**
\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
QPE/Application/\e{appname} channel, the appMessage() signal is
emitted. There are also flush() and reload() signals, which
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.
