41 | \brief The QPEApplication class implements various system services | ||
42 | that are available to all Qtopia applications. | ||
43 | |||
44 | Simply by using QPEApplication instead of QApplication, a standard Qt | ||
45 | application becomes a Qtopia application. It automatically follows | ||
46 | style changes, quits and raises, and in the | ||
47 | case of \link docwidget.html document-oriented\endlink applications, | ||
48 | changes the currently displayed document in response to the environment. | ||
49 | |||
50 | To create a \link docwidget.html document-oriented\endlink | ||
51 | application use showMainDocumentWidget(); to create a | ||
52 | non-document-oriented application use showMainWidget(). The | ||
53 | keepRunning() function indicates whether the application will | ||
54 | continue running after it's processed the last \link qcop.html | ||
55 | QCop\endlink message. This can be changed using setKeepRunning(). | ||
56 | |||
57 | A variety of signals are emitted when certain events occur, for | ||
58 | example, timeChanged(), clockChanged(), weekChanged(), | ||
59 | dateFormatChanged() and volumeChanged(). If the application receives | ||
60 | a \link qcop.html QCop\endlink message on the application's | ||
61 | QPE/Application/\e{appname} channel, the appMessage() signal is | ||
62 | emitted. There are also flush() and reload() signals, which | ||
63 | are emitted when synching begins and ends respectively - upon these | ||
64 | signals, the application should save and reload any data | ||
65 | files that are involved in synching. Most of these signals will initially | ||
66 | be received and unfiltered through the appMessage() signal. | ||
67 | |||
68 | This class also provides a set of useful static functions. The | ||
69 | qpeDir() and documentDir() functions return the respective paths. | ||
70 | The grabKeyboard() and ungrabKeyboard() functions are used to | ||
71 | control whether the application takes control of the device's | ||
72 | physical buttons (e.g. application launch keys). The stylus' mode of | ||
73 | operation is set with setStylusOperation() and retrieved with | ||
74 | stylusOperation(). There are also setInputMethodHint() and | ||
75 | inputMethodHint() functions. | ||
