\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.

/*!
\fn void QPEApplication::timeChanged();
This signal is emitted when the time jumps forward or backwards
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
QPE/Application/<i>appname</i> QCop channel for this application.
The slot to which you connect this signal uses \a msg and \a data
in the following way:
\code
void MyWidget::receive( const QCString& msg, const QByteArray& data )
{
QDataStream stream( data, IO_ReadOnly );
if ( msg == "someMessage(int,int,int)" ) {
int a,b,c;
