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. \ingroup qtopiaemb */ /*! \fn void QPEApplication::clientMoused() \internal */ /*! \fn void QPEApplication::timeChanged(); This signal is emitted when the time changes outside the normal passage of time, i.e. if the time is set backwards or forwards. */ /*! \fn void QPEApplication::clockChanged( bool ampm ); This signal is emitted when the user changes the clock's style.
